Abstract
The present invention relates to the preparation of active carbon, which particularly belongs to a method for preparing active carbon for vehicles by using straws and sawdust. An acidic catalyst solution is added to straw powder or sawdust powder whose particle size is from 80 to 120 meshes, and mixtures are fully ground in a mill to be viscous agglomerates, and the viscous agglomerates are pressed to be strips in an ordinary forming machine or spiral extruder. Carbon strips are solidified, carbonized and activated in a heating furnace, inorganic constituents are removed by pickling and water washing, and the active carbon is formed by drying. The active carbon produced by the present invention has the advantages of high absorption performance, high desorption performance and high mechanical strength.
Description
Technical field
The invention belongs to Preparation of Activated Carbon, especially belong to the method for utilizing straw and sawdust to make vehicular active carbon.
Background technology
In view of the good adsorptivity of gac, it is by extensive sorbing material as gas phase or liquid phase.The grade vehicle gac is mainly used in automobile and reclaims gasoline, with save energy, prevent to pollute, and this purposes requires gac that normal butane or gasoline are had high adsorptive value (normal butane active adsorption amount＞11g/100ml) and high rigidity, take a broad view of other wood substance grain Activated Carbon Production methods both at home and abroad, what have is raw material with the wood charcoal powder, make binding agent with oil system or carbobitumen, moulding in extruding machine, at high temperature form product again with steam activation, what have is raw material resol with the wood activated charcoal powder, fluorine resin, Resins, epoxy, urea-formaldehyde resin, lignin resin, atlapulgite and pitch etc. are made binding agent, again through mixing, behind the extrusion moulding, direct heating solidifies and forms; The wood activated charcoal powder with below the particle diameter 50 μ m that has adds the fluorine resin of protofibril voltinism, the water-soluble inorganic salt powder is mixing with the alcohol auxiliary agent that mixes, with fluorinated ethylene propylene be converted into fibrous after, the thing that will mix makes desirable shape, soak in a tepid bath then, the stripping inorganic components, then dry, heat treated forms, what have is raw material with the wood chip, zinc chloride is an activator, adds glue paste and additive through the extrusion molding of mixing, and forms product or the like through charing, activation, washing and oven dry supervisor again.Yet in order to last method, what have can not get high adsorptive power, and what have can not get qualified physical strength, thus have because of this personal value of binding agent height cost height.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming, provide a kind of utilize straw, sawdust and catalyzer not in addition adding additives produce have high absorption, high desorption performance, high strength and the simple grade vehicle process of active carbon of moulding.
The method applied in the present invention is: with particle diameter 80-120 purpose straw powder or sawdust powder, add the chlorination zinc solution and in runner milling, fully be ground to the heavy-gravity agglomerate, its zinc bits are than being 1.2-1.8: 1, in shaper or spiral extruding machine, suppress slivering again, sketching charcoal enters in the process furnace through overcuring, charing and activation, remove inorganic components through pickling, washing again, oven dry has formed has high absorption, high desorption performance, high-intensity vehicular active carbon.
The invention has the advantages that straw can instead of part or whole sawdust, enlarged raw material sources, the present invention can obtain that homogeneous densification, physical strength are big, adsorptive power and all strong granulated active carbon of desorption ability.
Embodiment
Introduce the present invention below in detail.
The present invention is with particle diameter 80-120 purpose straw powder or sawdust powder, add catalyzer--liquor zinci chloridi, general liquor zinci chloridi concentration is that 63--66 ° of Be ' zinc bits ratio is 1.2-1.8: 1, in runner milling, fully be ground to the heavy-gravity agglomerate, in shaper or spiral extruding machine, suppress slivering, sketching charcoal enters in the continuous tunnel furnace through overcuring, charing, activation, solidification value is 100-200 ℃, and be 4-8 hour set time, and the carbonization temperature 200-400 ℃ time is that 10-60 minute and activation temperature are 400--600 ℃, time is 10-60 minute, again through overpickling, washing is removed the inorganic components oven dry and is formed gac.
Principle of the present invention is: the inorganic components (for example zinc chloride) that the present invention uses be catalyzer be again binding agent, because the viscosity of the viscosity ratio water of solder(ing)acid is big 300 times, so need not to add any binding agent, as long as straw powder or sawdust powder are mixed, till xylogen and Mierocrystalline cellulose fully be ground to the height homodisperse and realize the part charing, moulding then, in the low-temperature curing stage, Mierocrystalline cellulose in the raw material or xylogen are decomposed into monose, aldose, furfural rapidly under catalyst action; Under catalyst action, the mutual again condensation poling heavy-gravity compound of these simple compounds, the compound dehydration forms condensing carbon structure, just becomes extremely hard gac through charing and activation again.
Most preferred embodiment of the present invention:
After particle diameter 80-120 purpose wood powder 200 gram added 350 milliliters of stirrings of liquor zinci chloridi that concentration is 65 ° of Be ', putting into three roller runner millings mills, color is by the faint yellow deep yellow that is converted into, be converted into coffee color again, powder is converted into the heavy-gravity bulk by dispersed, block is put into common bundle face machine make strip, can spread a little fine work powdered carbons on the sketching charcoal surface for preventing mutual bonding, then sketching charcoal is contained in the enamel tray, put into the drying baker that mixes up temperature in advance, earlier 100 ℃ of heating 2 hours, again 140 ℃ of heating 6 hours, in the rectangular box of stainless steel of then bar being packed into, add loam cake, put into muffle furnace, earlier in 300 ℃ of insulations 30 minutes (charing), again in 450 ℃ of insulations 30 minutes (activation), take out, after the cooling, earlier once with the 10%HCL washing, till reaching 4-6 with hot water repetitive scrubbing to pH value then, washed particle charcoal was dried 3 hours in 150 ℃ drying baker.
