Den foreliggende opfindelse angâr en fremgangsmâde til adskillelse af en komponent fra et fluidum, ved hvilken fluidet bringes i kontakt med partikler af en syntetisk polymer, som har indeholdt mindst en car-bonfikserende gruppe og er blevet underkastet en varmebehandling (pyro-5 lyse), hvilke varmebehandlede partikler har et carbonindhold pâ mindst 85 vægt% og et carbon-til-hydrogen atomforhold fra 1,5:1 til 20:1.The present invention relates to a method of separating a component from a fluid in which the fluid is contacted with particles of a synthetic polymer which have contained at least one carbon-fixing group and have been subjected to a heat treatment (pyrolysis). said heat treated particles having a carbon content of at least 85% by weight and a carbon-to-hydrogen atomic ratio of 1.5: 1 to 20: 1.
Det mest almindeligt anvendte adsorptionsmiddel er idag aktiveret carbon. Til fremstillingen af aktiveret carbon til industrielt formai anvendes et bredt spektrum af carbonholdige udgangsmaterialer 10 sâsom antracit og bituminost kul, koks, carboniserede flager, tprv, etc. Sâdanne materialers egnethed afhænger af et lavt askeindhold og tilgæn-gelighed i en ensartet og ikke skiftende kvalitet. Disse materialer har imidlertid fplgende ulemper: 15 a) vanskelig og bekostelig termisk regenerering b) hpje regenereringstab pâ 10% pr. cyklus c) skprhed af parti klerne af aktivt carbon d) mange! pâ kontrol med udgangsmaterialer.The most commonly used adsorbent today is activated carbon. For the manufacture of activated carbon for industrial use, a wide range of carbonaceous starting materials 10 such as anthracite and bituminous coal, coke, carbonized flakes, tprv, etc. are used. Such suitability depends on low ash content and availability in uniform and non-changing quality . However, these materials have the following drawbacks: a) difficult and expensive thermal regeneration b) high regeneration loss of 10% per annum. cycle c) the freshness of the batch of activated carbon d) many! on control of starting materials.
20 Til undgâelse af disse ulemper anvendes sorptionsmidler opnâet ved pyrolyse af syntetiske polymerer. Fra DD-patentskrift nr. 63.768 kendes f.eks. et pyrolyseprodukt af et sulfoneret styren-divinylbenzencopoly-merisat.To avoid these drawbacks, sorbents obtained by pyrolysis of synthetic polymers are used. It is known from DD patent specification No. 63,768, for example. a pyrolysis product of a sulfonated styrene-divinylbenzene copolymerate.
De pyrolyserede partikler udviser et carbon-til-hydrogen forhold 25 fra 1,5:1-20:1, fortrinsvis 2,0:1-10:1, mens aktivt carbon normalt har et meget hpjere C/H-forhold, som mindst er stdrre end 30:1, jf. Carbon and Graphite Handbook, Charles L. Mante!!, Interscience Publishers, N.Y.The pyrolyzed particles exhibit a carbon-to-hydrogen ratio of 25: 1.5: 1-20: 1, preferably 2.0: 1-10: 1, while active carbon usually has a much higher C / H ratio which at least is greater than 30: 1, see Carbon and Graphite Handbook, Charles L. Mante !!, Interscience Publishers, NY
1968, side 198). De pyrolyserede partikler indeholder mindst 85 vægt% carbon, mens den resterende de! i hovedsagen udgpres af hydrogen, 30 alkalimetaller, jordalkal installer, nitrogen, oxygen, svovl og chlor, idet disse stoffer hidrprer fra udgangspolymeren eller de funktionelle grupper (carbonfikserende grupper). Hydrogen, oxygen, svovl, nitrogen, alkalimetaller, overgangsgruppemetaller, jordalkalimetaller og andre grundstoffer kan ogsâ hidrpre fra fyldstoffer, som er sat til de porpse 35 polymerer for at tjene som katalysator og/eller carbonfikserende grupper eller give en anden virkning.1968, page 198). The pyrolyzed particles contain at least 85% by weight of carbon, while the remaining de! essentially hydrogen, 30 alkaline metals, alkaline earths, nitrogen, oxygen, sulfur and chlorine, these substances derived from the starting polymer or functional groups (carbon fixing groups). Hydrogen, oxygen, sulfur, nitrogen, alkali metals, transition group metals, alkaline earth metals, and other elements may also be derived from fillers added to the porous polymers to serve as catalyst and / or carbon fixing groups or to provide a different effect.

2 med adsorptionskapaciteter som langt overgâr aktivt kuls, foreslâs det ifdlge opfindelsen, at der som syntetisk polymer anvendes en makroporps harpiks, og at de pyrolyserede parti kler udviser et overfladeareal pâ 50 p p til 1500 m/g, hvoraf 6 til 700 m /g hidrdrer fra makroporer med en gen-5 nemsnitlig kritisk dimension fra 50 til 100.000 A og resten af over-fladearealet fra mindre porer med en gennemsnitlig kritisk dimension fra 2 til 50 A.2 with adsorption capacities far exceeding active carbon, it is proposed according to the invention that as a synthetic polymer, a macroporps resin be used and that the pyrolysed particles exhibit a surface area of 50 pp to 1500 m / g, of which 6 to 700 m / g prevents from macropores with an average critical dimension of 50 to 100,000 A and the rest of the surface area from smaller pores with an average critical dimension of 2 to 50 A.
I foretrukne udfdrelsesformer af opfindelsen adskilles enten en organisk komponent fra et væskeformigt medium eller en komponent fra en 10 gasformig blanding, idet den makropordse syntetiske polymer som inde-holder en carbonfikserende gruppe er afledt af en eller flere etylenisk umættede monomerer eller monomerer, som kan kondenseres til den makro-porpse polymer, eller blandinger deraf.In preferred embodiments of the invention, either an organic component is separated from a liquid medium or a component from a gaseous mixture, the macroporse synthetic polymer containing a carbon-fixing group being derived from one or more condensable ethylenically unsaturated monomers or monomers. to the macro-porous polymer, or mixtures thereof.
En anden foretrukket udfdrelsesform af opfindelsen er rettet pâ ad-15 skillelsen af organiske komponenter fra blod, hvortil de fdrnævnte pyrolyserede partikler ligeledes anvendes.Another preferred embodiment of the invention is directed to the separation of organic components from blood to which the aforementioned pyrolysed particles are also used.
Til nærmere belysning af opfindelsen beskrives forst de pyrolyserede partikler af en makropords syntetisk polymer og deres fremstilling.For a more detailed illustration of the invention, first, the pyrolyzed particles of a macropord synthetic polymer are described and their preparation.
De af fortrînsvis kugler eller perler med en betydelig strukturel styrke 20 og sammenhæng. De brækker ikke let i stykker og danner ikke nogen stdv-partikler, sâledes som det er tilfældet med aktivt carbon. Da de ikke let gâr i stykker, er regenereringstabet hyppigt 1 avéré, end hvad der er sædvanligt for aktivt carbon.Preferably, they are balls or beads of considerable structural strength and coherence. They do not break easily and do not form any dust particles, as is the case with activated carbon. Since they do not break easily, the regeneration loss is often 1 averé than is usual for activated carbon.
Inkorporering af pnskelige elementer og funktionelle grupper til 25 forbedring af absorptionsevnen over for specifikke adsorbater gennemfp-res let. Kontrol af den gennemsnitlige porestdrrelse og porestdrrelses-fordelingen gennemfpres meget lettere med veldefinerede syntetiske ud-gangsmaterialer. Denne forpgede kontrol tillader fremstilling af adsorp-tionsmidler, som er udformet med henblik pâ specifikke adsorbater og med 30 adsorptionskapaciteter, som er langt storre, end hvad der er muligt med aktiverede carbontyper.Incorporation of desirable elements and functional groups to improve absorbency to specific adsorbates is readily accomplished. Control of the average pore size and pore size distribution is much easier to perform with well-defined synthetic starting materials. This preliminary control permits the production of adsorbents designed for specific adsorbates and with 30 adsorption capacities far greater than is possible with activated carbon types.
Det er h0jst dnskeligt, at varmebehandlingen, dvs. pyrolysen gen-nemfpres i en inert atmosfære i form af f.eks. argon, néon, hélium, ni-trogen eller lignende, under anvendelse af perler af makroporps synte-35 tisk polymer substitueret med en carbonfikserende gruppe, som tillader polymeren at forkulle uden at smelte, sâledes at den makroporose struk-tur bevares, og et hdjt udbytte af carbon frembringes. Blandt egnede carbonfikserende grupper er sulfonat-, carboxyl-, amin-, halogen-, 3It is highly desirable that the heat treatment, ie. the pyrolysis is carried out in an inert atmosphere in the form of e.g. argon, neon, helium, nitrogen or the like, using beads of macroporps synthetic polymer substituted with a carbon-fixing group which allows the polymer to char without melting, thus preserving the macroporous structure and a high yield of carbon is generated. Suitable carbon-fixing groups are sulfonate, carboxyl, amine, halogen, 3

oxygen-, sulfonatsalt-, carboxylatsalt- og kvarternær aminsaltgrupper.oxygen, sulfonate salt, carboxylate salt and quaternary amine salt groups.
Disse grupper indfdres i udgangspolymeren ved hjælp af velkendte konven-tionelle teknikker, sâsom de omsætninger, der anvendes til at gdre poly-merer funktionelle til fremstilling af ionbytningsharpikser. Carbonfik-5 serende grupper kan ogsâ frembringes ved opsugning af en reaktiv præ-kursor derfor i porerne af den makropordse polymer, som derefter, eller under opvarmning, kemisk binder carbonfikserende grupper til polymeren. Eksempler pâ sâdanne reaktive prækursorer omfatter svovlsyre, oxida-tionsmidler, salpetersyre, Lewis syrer, acrylsyre og lignende.These groups are incorporated into the starting polymer by well known conventional techniques, such as the reactions used to make polymers functional for the production of ion exchange resins. Carbon fixing groups can also be produced by aspirating a reactive precursor, therefore, into the pores of the macroporded polymer which then, or during heating, chemically bond carbon fixing groups to the polymer. Examples of such reactive precursors include sulfuric acid, oxidizing agents, nitric acid, Lewis acids, acrylic acid and the like.
10 Temperaturer, som er passende for den termiske omdannelse, ligger almindeligvis i omrâdet fra 300°C til ca. 900°C, skdnt hdjere temperaturer kan være egnede, afhængigt af polymeren, som skal behandles, og den dnskede sammensætning af det færdige pyrolyserede produkt. Ved temperaturer over ca. 700°C nedbrydes udgangspolymeren vidtgâende under 15 dannelse af porer af molekylsigtestdrrelse i produktet, dvs. en gennem-snitlig kritisk dimension pâ ca. 4 - 6 A, hvorved en foretrukket klasse af adsorptionsmidler ifdlge opfindelsen frembringes. Ved 1 avéré temperaturer ligger den gennemsnitlige kritiske dimension af de termisk dannede porer sædvanligvis i omrâdet fra ca. 6 A til sâ meget som 50 A. Omrâdet 20 mellem ca. 400°C og 800°C er et foretrukket temperaturomrâde for pyroly-sen. Som det senere vil blive forklaret mere fuldstændigt, er tempera-turkontrol væsentlig for, at det dnskede produkts sammensætning, over-fladeareal, porestruktur og andre fysiske karakteristika kan frembringes. Varigheden af den termiske behandling er relativt uvæsentlig, 25 forudsat at en minimumsindvirkningstid af den forhdjede temperatur over-holdes.Temperatures suitable for the thermal conversion are generally in the range of 300 ° C to approx. 900 ° C, although higher temperatures may be suitable, depending on the polymer to be treated and the composition of the finished pyrolyzed product. At temperatures above approx. 700 ° C, the starting polymer is degraded extensively to form pores of molecular sieve test in the product, ie. an average critical dimension of approx. 4 - 6 A, thereby producing a preferred class of adsorbents according to the invention. At 1 ambient temperature, the average critical dimension of the thermally formed pores is usually in the range of approx. 6 A to as much as 50 A. The area 20 between approx. 400 ° C and 800 ° C is a preferred temperature range for the pyrolysis. As will be more fully explained later, temperature control is essential for the composition, surface area, pore structure and other physical characteristics of the product to be produced. The duration of the thermal treatment is relatively insignificant, provided that a minimum impact time of the elevated temperature is observed.
Ved kontrol af betingelserne for den termiske dekomponering, og i særdeleshed af temperaturen, indstilles grundstofsammensætningen, og særlig vigtigt carbon-til-hydrogenatom forholdet (C/H) i de færdigfrem-30 stillede parti kler pâ den dnskede mâde. Kontrolleret varmebehandling giver partikler, som med hensyn til værdien af C/H forholdet er en mel-lemting mellem aktiveret carbon og de kendte polymer-adsorptionsmidler.By checking the conditions of the thermal decomposition, and in particular the temperature, the elemental composition, and particularly important the carbon-to-hydrogen atom ratio (C / H) in the prepared parts, is adjusted in the desired manner. Controlled heat treatment produces particles which, with respect to the value of the C / H ratio, are an intermediate between activated carbon and the known polymer adsorbents.

Slutproduktets porestruktur skal hâve mindst to forskellige sæt af porer med forskellig gennemsnitlig stprrelse, dvs. at slutproduktet skal hâve multimodal porefordeling. De stprre porer hidrprer fra den som udgangsmateriale anvendte makroporpse harpiks, som fortrinsvis indeholder 30 makroporer i omrâdet fra 50 til 100.000 A i gennemsnitlig kritisk dimension. De tidligere nævnte mindre porer, hvis gennemsnitlige kritiske dimension i almindelighed ligger i omrâdet fra 4 til 50 A, mâ i vid ud-strækning tilskrives pyrolysen og maksimumtemperaturen under pyrolysen.The pore structure of the final product must have at least two different sets of pores of different average sizes, ie. that the final product should have multimodal pore distribution. The larger pores are derived from the macroporps resin used as the starting material, which preferably contains 30 macropores in the range of 50 to 100,000 A in average critical dimension. The smaller pores mentioned earlier, whose average critical dimension generally ranges from 4 to 50 A, must be largely attributed to the pyrolysis and the maximum temperature during the pyrolysis.

Den ikke-porpse "gel"-harpiks har et overfladeareal, som ligger et godt stykke under omrâdet for udgangsmaterialerne if0lge opfindelsen, og den giver et produkt, som har et overfladeareal, der ligger væsentligt under de varmebehandlede makroporpse harpiksers.with a factor of approx. 2. The non-porous "gel" resin has a surface area which is well below the range of the starting materials of the invention, and provides a product having a surface area substantially below the heat-treated macroporse resins.
5 Pyrolysens varighed afhænger af det tidsrum, som er npdvendigt til fjernelse af de flygtige komponenter fra den pâgældende polymer og den valgte fremgangsmâdes varmeoverfprselskarakteristika. Pyrolysen sker i almindelighed meget hurtigt, nâr varmeoverfdrslen sker hurtigt, f.eks. i en ovn, hvor et tyndt lag materiale pyrolyseres, eller i et fluidiseret 10 leje. For at forhindre den pyrolyserede polymer i at brænde reduceres polymerens temperatur sædvanligvis til ikke over 400°C, fortrinsvis ikke over 300°C, fpr det pyrolyserede materiale udsættes for luft. Den mest foretrukne udfprelse af fremgangsmâden omfatter hurtig opvarmning til maksimumtemperaturen, fastholdelse af temperaturen pà maksimet i et kort 15 tidsrum (af stdrrelsesordenen 0-20 minutter) efterfulgt af hurtig re-duktion af temperaturen til stuetemperatur fpr udtagning af prpven. Pro-dukter til anvendelse ifplge opfindelsen er blevet fremstillet ved denne foretrukne fremgangsmàde ved opvarmning til 800°C og afkpling i et tidsrum pâ 20 - 30 minutter. Ogsà længere perioder ved de forhdjede tempera-20 turer er tilfredsstillende, da der ikke synes at indtræffe yderligere dekomponering, medmindre temperaturen forpges.The duration of the pyrolysis depends on the amount of time required to remove the volatile components from the polymer in question and the heat transfer characteristics of the selected method. Pyrolysis generally occurs very quickly when the heat transfer is rapid, e.g. in an oven where a thin layer of material is pyrolyzed, or in a fluidized bed. In order to prevent the pyrolysed polymer from burning, the temperature of the polymer is usually reduced to not more than 400 ° C, preferably not above 300 ° C, before the pyrolysed material is exposed to air. The most preferred embodiment of the method comprises rapid heating to the maximum temperature, maintaining the temperature at the maximum for a short period of time (of the order of 0-20 minutes) followed by rapid reduction of the temperature to room temperature prior to sampling. Products for use in accordance with the invention have been prepared by this preferred method of heating to 800 ° C and decoupling for a period of 20 to 30 minutes. Also, longer periods at the elevated temperatures are satisfactory as no further decomposition appears to occur unless the temperature is missed.
Smâ mængder af aktiverende gasser sâsom C02, S03, 02, H20 eller kombinationer deraf har en tendens til at reagere med polymeren under pyrolysen og forpge overfladearealet af det færdige materiale derved.Small amounts of activating gases such as CO 2, SO 3, 02, H 2 O or combinations thereof tend to react with the polymer during the pyrolysis, thereby purging the surface area of the finished material.
25 Det er valgfrit at anvende sâdanne gasser, og de kan anvendes til opnà-else af specîelle karakteristika af adsorptionsmidlerne.Such gases are optional and can be used to obtain special characteristics of the adsorbents.
De polymerer, der kan anvendes som udgangsmaterialer til fremstil-ling af de pyrolyserede harpikser, omfatter makropordse homopolymerer eller copolymerer af én eller flere monoethylenisk eller polyethylenisk 30 umættede monomerer eller monomerer, som ved kondensation kan omsættes til frembringelse af makroporpse polymerer og copolymerer. De makropo-r0se harpikser, der anvendes som prækursorer ved dannelsen af de makro-porpse varmebehandlede polymerer, er kendte. Et hvilket som helst af de kendte materialer af denne type, som har en passende carbonfikserende 35 gruppe, er egnet. De foretrukne monomerer er sâdanne alifatiske og aro-matiske materialer, som er ethylenisk umættede.The polymers which can be used as starting materials for the preparation of the pyrolyzed resins include macroporous homopolymers or copolymers of one or more monoethylenically or polyethylenically unsaturated monomers or monomers which can be converted by condensation to produce macroporous polymers and copolymers. The macroporous resins used as precursors in the formation of the macroporse heat-treated polymers are known. Any of the known materials of this type which have a suitable carbon fixing group are suitable. The preferred monomers are such aliphatic and aromatic materials which are ethylenically unsaturated.
Som eksempler pâ passende monoethylenisk umættede monomerer, som kan anvendes til fremstilling af den makroporpse harpiks, kan nævnes:Examples of suitable monoethylenically unsaturated monomers which can be used to prepare the macroporse resin include:

Aktivering med reaktive gasser er en procès, som af og til kan være pnskelig af hensyn til modifikation af adsorptionsegenskaberne, men det er ikke nogen nedvendig de! af opfindelsen. Som det vises i tabel III og IV 5 nedenfor, influeres adsorptionsegenskaberne markant af maksimumtempera-turen, som harpiksen udsættes for. Som vist i tabel III, frembringer en temperatur pâ 500°C et adsorptionsmiddel, som er optimalt til fjernelse af chloroform fra vand.steps of heat treating polymers as described above. Activation with reactive gases is a process that may sometimes be feasible for modification of adsorption properties, but it is not necessary! of the invention. As shown in Tables III and IV 5 below, the adsorption properties are significantly influenced by the maximum temperature to which the resin is exposed. As shown in Table III, a temperature of 500 ° C produces an adsorbent which is optimal for removing chloroform from water.
Harpikser, som er varmebehandlet ved 800°C, er i stand til selek-10 tivt at adsorbere molekyler efter stprrelse (se tabel IV). Den ved 800°C behandledes harpiks er endnu mere effektiv til adskillelse af hexan og carbontetrachlorid end vist i tabel IV, da næsten ait CCI^ ad-sorberes pâ overfladen af makroporerne og ikke i mikroporerne. Den til-syneladende bedre selektivitet af den kommercielle carbonmolekylsigte 15 (eksempel 5) skyldes sandsynligvis meget mindre overf1 adeareal af makroporerne. Harpiksen, som er varmebehandlet ved 500°C (nr. 1 i tabel IV) udviser meget mindre selektivitet over for de to molekyler med forskel-lig stprrelse og understreger sâledes den vigtige indflydelse, som maksimumtemperaturen under varmebehandlingen har pâ adsorptionsegen-20 skaberne. 1Resins heat-treated at 800 ° C are capable of selectively adsorbing molecules by size (see Table IV). The resin treated at 800 ° C is even more effective at separating hexane and carbon tetrachloride than shown in Table IV, since almost all CCl4 is adsorbed on the surface of the macropores and not in the micropores. The apparent better selectivity of the commercial carbon molecular sieve 15 (Example 5) is probably due to much less surface area of the macropores. The resin, which is heat treated at 500 ° C (# 1 in Table IV), exhibits much less selectivity to the two molecules of different sizes and thus emphasizes the important influence that the maximum temperature during the heat treatment has on the adsorption properties. 1

Kolonnestr0mningshastigheden er derfor 80 spjlevolumener/min. Aile eksperimenter gennemf0res ved omgivelsestempe-ratur og et overtryk pâ 110 kPa. En delstr0m pâ 10 ml/min. udtages fra afgangsgassen og indfpres i en flammeionisationsdetektor til kontinuert vinylchloridanalyse. Ogsâ konventionelle Rohm and Haas adsorptionsmidler 20 og en type Calgon aktiveret carbon undersoges. Resultaterne vises neden-for.Adsorption of wine chloride 10 3 10 cm sample is placed in a stainless steel column with an internal diameter of 1,69 cm. The column height is then 5.05 cm. Using a dilution equipment with a mixing chamber, a gas stream of 580 ppm vinyl chloride is developed in air and passed through the column at a volumetric flow rate of 800 ml / min. Therefore, the column flow rate is 80 rpm. All experiments are carried out at ambient temperature and an overpressure of 110 kPa. A partial flow of 10 ml / min. is extracted from the exhaust gas and injected into a flame ionization detector for continuous vinyl chloride analysis. Also conventional Rohm and Haas adsorbents 20 and a type of Calgon activated carbon were investigated. The results are shown below.

Better resistance to fracture is expected to result in a highly extended effective service life compared to granular carbon, for which the loss of wear can be large. Partitioning of particulate matter by the pyrolyzed polymers is also not possible for their use in applications where activated carbon is unacceptable, such as by blood treatment.

il Carbonfikserende arupperil Carbon fixing groups
Det er blevet vist, at talrige grupper bevirker carbonfiksering 15 under pyrolyse. En partiel liste over grupper og deres effektivitet er anfprt i tabel XV. Gruppens eksakte kemiske natur er uvæsentlig, da en hvilken som helst gruppe, der tjener til at forhindre forflygtigelse af carbonet under pyrolysen, er tilfredsstillende.Numerous groups have been shown to effect carbon fixation 15 during pyrolysis. A partial list of groups and their effectiveness is given in Table XV. The exact chemical nature of the group is immaterial, as any group which serves to prevent volatilization of the carbon during pyrolysis is satisfactory.
20 iil Opsuaede carbonfikserende midler20 µl of aspirated carbon fixing agents
Opfyldning af en makropor0s copolymers porer med en reaktiv sub-stans forud for pyrolysen tjener til at forhindre forflygtigelse af carbonet i copolymeren. I tilfældet, hvor der anvendes svovlsyre, er det blevet vist, at materialet gennemgâr en sulfoneringsreaktion under op-25 varmning, som frembringer en substans lig udgangsmaterialet i prpve 1 i tabel XV. Det stprre carbonudbytte, der opnâs via opsugning frem for ved præsulfonering, er uventet og viser, at fremgangsmâden kan være bedre end andre carbonfikseringsteknikker.Filling the pores of a macropore copolymer with a reactive substance prior to pyrolysis serves to prevent volatilization of the carbon in the copolymer. In the case where sulfuric acid is used, it has been shown that the material undergoes a sulphonation reaction under heating which produces a substance similar to the starting material in sample 1 of Table XV. The higher carbon yield obtained by aspiration rather than by presulfonation is unexpected and shows that the method may be better than other carbon fixation techniques.
30 iiil Impræanerede polvmerer30 iiil Impregnated Polymers
Imprægnering er eksemplificeret ved nr. 4 i tabel XVI, hvor porerne i en type carbon black indeholdende S/DVB-copolymer opfyldtes med H2S04 og pyrolyseredes. Carbonudbyttet er h0jere end i det tilsvarende ekspe-riment (prpve 1), som er gennemf0rt uden tilstedeværelsen af carbon 35 black.Impregnation is exemplified by # 4 in Table XVI where the pores of a type of carbon black containing S / DVB copolymer were filled with H 2 SO 4 and pyrolyzed. The carbon yield is higher than in the corresponding experiment (sample 1), which was carried out without the presence of carbon black.

Ledningsvand fra en byvandforsynîng (Spring House, Pennsylvania) som var tilsat CHC13 til en koncentration pâ ca. 1 ppm ledtes under hur-tig strpmning pâ 0,535 liter pr. liter pr. minut gennem tre kolonner, 5 som indeholdt pyrolyseret styren/divinylbenzen ("Amberlite 200") pyroly-seret polymer, og som parailelt var forbundet med en fælles kilde. Af-gangsstrpmmen opsamledes, og CHClj-koncentrationen màltes ved hjælp af GC/EC analyse. Resultaterne, som er anfprt i tabel XVIII, viser, at 500°C prpven udkonkurrerer kontrol-adsorptionsmidlerne med en bred mar-10 gin. For at checke reproducerbarheden af disse resultater underspgtes en anden portion 500°C harpiks under identiske omstændigheder, og den var signifikant bedre end den fprste prpve. Den bedste 500° harpiksprpve kan behandle ca. 14 gange sa mange spjlevolumener ledningsvand som det gra-nulære aktiverede carbon. Ydeevneforskellen mellem de to 500° pyrolyse-15 rede harpikspr0ver kan henfpres til det signifikant lavere oxygenindhold i den bedste pr$ve. Mindre oxygen antages at fpre til en mere hydrofob overfl ade, hvorved overfladens tiltrækning over for tungt oplpselige or-ganiske forbindelser som chloroform forpges. Det er blevet vist, at bâde damp og oplgsningsmiddel regenererer 500°C harpikserne effektivt. Smâ 20 kolonner med charge-belastet harpiks behandledes med damp og methanol og udviste derefter samme charge-ligevægtkapacitet som fpr regenerering. Et andet sst kolonneeksperimenter gennemfprtes efter regenerering af kolon-nerne med 5 spjlevolumener methanol. Resultaterne findes i tabel XVIII.Tap water from an urban water supply (Spring House, Pennsylvania) to which CHC13 was added to a concentration of ca. 1 ppm was conducted under rapid stocking of 0.535 liters per liter. liter per liter. per minute through three columns, 5 containing pyrolyzed styrene / divinylbenzene ("Amberlite 200") pyrolyzed polymer, and which were connected in parallel to a common source. The residual current was collected and the CHCl 2 concentration was measured by GC / EC analysis. The results listed in Table XVIII show that the 500 ° C sample outperforms the control adsorbents by a wide margin. In order to check the reproducibility of these results, another portion of 500 ° C resin was examined under identical conditions and was significantly better than the first sample. The best 500 ° resin sample can treat approx. 14 times as many flush volumes of tap water as the granular activated carbon. The performance difference between the two 500 ° pyrolysed resin samples can be attributed to the significantly lower oxygen content in the best sample. Less oxygen is assumed to feed to a more hydrophobic surface, thereby reducing the attraction of the surface to heavily soluble organic compounds such as chloroform. Both steam and solvent have been shown to efficiently regenerate the 500 ° C resins. Small 20 column loaded charge resins were treated with steam and methanol and then exhibited the same charge equilibrium capacity as fpr regeneration. Another six column experiment is performed after regenerating the columns with 5 volumes of methanol. The results are in Table XVIII.
Anden cyklus kapaciteterne af den pyrolyserede harpiks (a) og det poly-25 mere adsorptionsmiddel er hpjere end kapaciteterne for den fprste cyklus, hvilket indikerer, at methanolen ud over fuldstændig regenerering fjernede nogle forureninger, som var til stede ved begyndelsen af den fsirste cykl us. Den lavere anden cykl us kapacitet for det aktiverede carbon indikerer ufuldstændig regenerering. Det pyrolyserede materiale 30 regenereres knap sâ let som "XAD-4", idet det kræver ca. 1 spjlevolumen regenereringsmiddel mere for opnâelse af en ækvivalent regenererings-grad. Aktiveret carbon regenereres signifikant mindre let, idet kun 62% regenerering opnâs efter 5 spjlevolumener methanol (beregnet ud fra for-holdet mellem kapaciteterne ved fprste og anden cyklus).The second cycle capacities of the pyrolyzed resin (a) and the polymer more adsorbent are higher than the capacities of the first cycle, indicating that the methanol, in addition to complete regeneration, removed some contaminants present at the beginning of the first cycle. . The lower second cycle us capacity of the activated carbon indicates incomplete regeneration. The pyrolyzed material 30 is barely regenerated as "XAD-4", requiring approx. 1 mirror volume of regenerant more to obtain an equivalent degree of regeneration. Activated carbon is significantly less easily regenerated, with only 62% regeneration achieved after 5 volumes of methanol (calculated from the ratio of first and second cycle capacities).

at være regenereret ufuldstændigt under de valgte regenereringsbetingel-ser. Oxygen-ætsning for0ger kun charge- og kolonnephenolkapaciteten lidt i sammenligning med den uætsede prækursor, men forpger regenererbarheden drastisk. Dannelse af porer i 6-40 A-omrâdet ved ætsning kan forpge dif-5 fusionshastigheden inden for parti klerne og derved tillade mere effektiv regenerering.to be incompletely regenerated under the selected regeneration conditions. Oxygen etching only slightly increases the charge and column phenol capacity compared to the etched precursor, but drastically reduces the regenerability. Formation of pores in the 6-40 A range by etching can accelerate the diffusion rate within the clusters, thereby allowing more efficient regeneration.
Det er intéressant, at 500°C prpven, som var fremragende til chloroform-fjernelse, havde en lav kapacitet for phénol. Da der i 800°C prpven fandtes porer med molekylsigtestprrelse og ikke i 500°C materia-10 let, er det sandsynligt, at de mindste porer er de aktive positioner for phénoladsorption.It is of interest that the 500 ° C sample, which was excellent for chloroform removal, had a low phenol capacity. Since in the 800 ° C sample, pores of molecular sieve size were found and not in the 500 ° C material, it is likely that the smallest pores are the active positions for phenol adsorption.
