Description

本発明は、活性カーボンの製造方法に関するものであり、特に、コーヒー豆のかすで活性カーボンを製造する方法を指す。   The present invention relates to a method for producing activated carbon, and particularly refers to a method for producing activated carbon from coffee beans.

活性カーボン（Activated Carbon）は相当特殊な孔穴結構を持ち、多孔性カーボンの集合性名称を得る。優れた表面積レート（一般に、５００−１５００ｍ2／gまで至る）という特性があるので、有機の汚染物質を吸い付けることに適用して、環境工業、食品及び医薬などの産業で広く応用される。 Activated carbon has a very special pore structure and gives the collective name for porous carbon. Because of its excellent surface area rate (generally up to 500-1500 m 2 / g), it can be applied to sucking organic pollutants and widely applied in industries such as environmental industry, food and medicine.

活性カーボンの種類は次の４種に分けられる。
１．粒状の活性カーボン（ＧＡＣ）は、主に、揮発性の有機化合物（ＶＯＣｓ）の処理と回収、空気の浄化（例えば、脱臭化）及び空気汚染の防止に応用される。 The types of activated carbon are classified into the following four types.
1. Granular activated carbon (GAC) is mainly applied in the treatment and recovery of volatile organic compounds (VOCs), air purification (eg, debromination) and prevention of air pollution.

２．粉状の活性カーボン（ＰＡＣ）は、主に、浄水工程（例えば、三ハロゲンメタン）、廃水工程及び食品工業（例えば脱色）などに応用される。
３．定性活性カーボンは、活性カーボンが再製及び定型のプロセスを経由して、特定産業の必要な形状に作られる。例えば、特殊気体の吸いつけ又は反応の触媒の載せ体として応用される。 2. Powdered activated carbon (PAC) is mainly applied to water purification processes (for example, trihalogen methane), waste water processes, food industry (for example, decolorization), and the like.
3. The qualitative activated carbon is made into a required shape of a specific industry through a process in which the activated carbon is remanufactured and fixed. For example, it is applied as a special gas sucking or reaction catalyst mount.

４．繊維状活性カーボンは、活性カーボンで繊維状の非織り布を作り、圧力降下を減らす。有機溶剤の回収に使われ、例えば、セミコンダクターの産業製造のプロセス、日常生活の空気浄化機及びエアコンの濾過網などに応用される。   4). Fibrous activated carbon creates a fibrous non-woven fabric with activated carbon and reduces pressure drop. Used for organic solvent recovery, for example, semiconductor manufacturing processes, daily life air purifiers and air conditioner filtration networks.

活性カーボンは、通常、高炭化及び低無機含量の物質を選んで原料として、活性カーボンの製造を行う。例えば、動物、植物又は鉱物などのカーボン多含量の物質を適当な処理プロセス（例えば、熱の***分解の反応）により加工したあとで、活性カーボンが作られる。   The activated carbon is usually produced by selecting a material having high carbonization and low inorganic content as a raw material. For example, activated carbon is made after processing a carbon-rich material such as an animal, plant or mineral by a suitable treatment process (eg, thermal fission degradation reaction).

現今の研究により、活性カーボンの原料は泥煤、褐煤、褐炭、煙煤、やしの実の殻、木材、廃棄の竹箸、木の屑、堅い果実の殻、さとうきびのかす、重油のかす、石油の焦、廃棄のタイヤ、汚い泥、稲の殻、とうもろこしの穂又は赤砂糖などがある。   According to current research, the raw materials for activated carbon are mud, brown crab, lignite, smoke, palm husk, wood, discarded bamboo chopsticks, wood scrap, hard fruit husk, sugar cane residue, heavy oil residue, There are oil scorch, waste tires, dirty mud, rice husk, corn ears or brown sugar.

一般に言えば、やしの実の殻及び堅い果実の殻は高密度を持ち、極めて高い揮発性もあるので、作られた活性カーボンは空気の浄化及び揮発性を具有する有機化合物（ＶＯＣｓ）の処理と回収に適用される。それに対して、木材及び木質素などの低密度の物質は浄水の工程に適用される。
さて、コーヒー豆のかすはコーヒー飲料及び相関製品の工場の主要食品の廃棄物である。人間がコーヒーを飲用する習慣は日々盛んである。 Generally speaking, since the coconut shells and hard fruit shells have a high density and are extremely volatile, the activated carbon produced is an organic compound (VOCs) that purifies air and is volatile. Applies to processing and recovery. On the other hand, low-density materials such as wood and wood are applied to the water purification process.
Now, coffee grounds are the main food waste of the coffee beverage and related products factory. The habit of drinking coffee is prosperous every day.

Please see Figure 1 first. 2 is a simplified process flowchart of a method for producing activated carbon from coffee bean residue according to an embodiment of the present invention. Detailed explanation of each step is as follows.

コーヒー豆のかすの前処理：
コーヒー豆のかすを洗浄、乾燥及び冷却し、夾雑物を取り出したあとで、砕く。
活性化剤に浸す：
前処理したあとのコーヒー豆のかすを炭酸カリウム、炭酸カルシウム又は炭酸マグネシウムなどの炭酸塩系の化学活性化剤に浸す。それで、活性化剤をコーヒー豆のかすの表面に吸い付ける。活性化剤の理想的な濃度は１０％−４０％である。１−２時間浸したあとで、コーヒー豆のかすを濾過及び乾燥させる。 Pre-treatment of coffee grounds:
After washing, drying and cooling the ground coffee beans, remove the impurities and crush them.
Soak in activator:
The ground coffee beans after pretreatment are soaked in a carbonate-based chemical activator such as potassium carbonate, calcium carbonate or magnesium carbonate. So the activator is sucked onto the surface of the coffee bean ground. The ideal concentration of activator is 10% -40%. After soaking for 1-2 hours, the coffee grounds are filtered and dried.

かまどでの炭化及び活性化プロセス：
上述の浸したあとのコーヒー豆のかす１００ｇを高温のかまどに入れる。高温のかまど装置は図２に示すようになる。高温のかまどの主体２１は、約１００ｃｍの高さの中空開閉できる矩形体である。その最高温度は１０５０℃まで至り、付加の温度制御装置で温度上昇のスピードを制御でき、加熱の時間を定温の反応のようにセットさせる。高温のかまどの主体２１の加熱エリア２２は、ステンレス材質で作られる熱の***及び分解用の反応管２３を含む。その長さはほぼ９０ｃｍで、管壁の厚さは０．５ｃｍで、管の内径は３．５ｃｍである。反応管２３の前予熱段は約２５ｃｍで、同恒温エリアは約５０ｃｍである。反応管２３自身は時計の方向または逆方向に沿って番号２４に示すように回転でき、反応の進行を促進させる。その他、加熱エリア２２の上方に保護カバー２５が配置され、加熱エリア２２の温度を維持させる。 Carbonization and activation process in the furnace:
Place 100 g of the above ground coffee beans in a hot oven. The high temperature furnace apparatus is as shown in FIG. The main body 21 of the high-temperature furnace is a rectangular body with a height of about 100 cm that can be opened and closed. The maximum temperature reaches 1050 ° C., and the temperature rise speed can be controlled by an additional temperature control device, and the heating time is set like a constant temperature reaction. The heating area 22 of the high-temperature furnace main body 21 includes a reaction tube 23 for splitting and decomposing heat made of stainless steel. Its length is approximately 90 cm, the tube wall thickness is 0.5 cm, and the inner diameter of the tube is 3.5 cm. The pre-heating stage of the reaction tube 23 is about 25 cm, and the constant temperature area is about 50 cm. The reaction tube 23 itself can be rotated along the clockwise direction or the reverse direction as indicated by reference numeral 24 to accelerate the progress of the reaction. In addition, a protective cover 25 is disposed above the heating area 22 to maintain the temperature of the heating area 22.

また、高温のかまど装置は気体のボンベ２６を含む。それで気体を提供して、熱の***及び分解用の反応管２３における空気を排除させる。それで、酸素がない条件で熱の***及び分解を行うと同時に、反応のあとの気体産物を取り出す。   Further, the high temperature furnace includes a gas cylinder 26. Thus, gas is provided to eliminate the air in the reaction tube 23 for heat splitting and decomposition.

Then, a temperature rise program is set from the operation panel. Then, the gas cylinder 26 is opened to fill the reaction tube 23 for heat splitting and decomposition. Further, the temperature is increased by 700-900 ° C. at a temperature increase speed of 10 ° C./min as shown in the temperature increase program of FIG. Then, the carbonization and activation processes are performed while the heat is splitting and decomposing, so that a crude product of activated carbon is obtained.

粗製品の後処理：
粗製品を２５０ｍｌの０．５N塩酸の溶液にいれる。８５℃で３０分の酸洗を行ったあと、気体抜きで酸液を濾過及び除去する。それから、８５℃の蒸留水を入れて、３０分の水洗を行って、水液を濾過及び除去する。水洗のプロセスは濾過液のＰＨ値＞６まで繰り返すように行われる。それらサンプルをアセトンに浸させ、超音波で１時間振動させる。また、気体抜きでアセトンを濾過して除く。のちに、蒸留水で何回か洗って、２００℃のベーキングオーブンに１２−２４時間ぐらい放置する。さらに、それを取り出し、乾燥装置にいれて、真空まで抜きながら冷却させる。そうすると、活性カーボンの最終製品が得られる。 Post-treatment of crude product:
The crude product is placed in 250 ml of 0.5N hydrochloric acid solution. After pickling at 85 ° C. for 30 minutes, the acid solution is filtered and removed by degassing. Then, distilled water at 85 ° C. is put in, washed with water for 30 minutes, and the aqueous solution is filtered and removed. The washing process is repeated until the PH value of the filtrate is> 6. The samples are soaked in acetone and sonicated for 1 hour. In addition, acetone is removed by gas removal. Later, it is washed several times with distilled water and left in a baking oven at 200 ° C. for about 12-24 hours. Further, it is taken out and put in a drying apparatus to be cooled while being evacuated. Then, the final product of activated carbon is obtained.

上述のプロセスで作られた活性カーボンを台湾大学の化学工業ディパートメント及び中央大学の化学工業ディパートメントに依頼し、Micromeritics Instrument CorporationのＡＳＡＰ２０００及び２００１タイプの微孔分析テスターでその表面積レートを測定する。測った表面積レートは約１３１７ m2／g である。表１は、現今、様々な活性カーボンの製造方法で作られた活性カーボンの表面積レートの比較を表す。 The activated carbon produced by the above process was commissioned to the chemical industry department of Taiwan University and the chemical industry department of Chuo University, and its surface area rate was measured with ASAP2000 and 2001 type micropore analysis tester of Micromeritics Instrument Corporation. To do. The measured surface area rate is about 1317 m 2 / g. Table 1 presently compares the surface area rates of activated carbons made with various activated carbon production methods.

以上の内容をまとめると、本発明のコーヒー豆のかすで活性カーボンを製造する方法で作った活性カーボンの表面積レートは１３１７m2／gの高いレーベルに至るので、極めて優れた吸い付け効果が得られる。結局、本発明は有効的にコーヒー豆のかすを環境工業及び食品などの産業で大量に使用される活性カーボン製品へ転換させ、廃棄物を資源化する目的を果たす。 In summary, the surface area rate of the activated carbon produced by the method for producing activated carbon from the coffee bean residue of the present invention reaches a high label of 1317 m 2 / g, so that an extremely excellent suction effect can be obtained. .
