本発明は、塊状に成形した活性炭素繊維からな
る吸着材に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adsorbent comprising activated carbon fibers formed into blocks.
従来から吸着剤として活性炭が最も広く用いら
れ、工業的に極めて有用であり、例えば各種工業
において粉末状あるいは粒状の形態で脱臭、脱色
及び有害物質の除去などに広範囲に使用されてい
る。 Activated carbon has conventionally been most widely used as an adsorbent and is extremely useful industrially, for example, in various industries in powder or granular form for deodorization, decolorization, and removal of harmful substances.
一方炭素物質の一種である炭素繊維は、軽くて
強い補強材料として各種強化プラスチツク成形物
の製造などに用いられているが、この炭素繊維を
活性化した、いわゆる活性炭素繊維も吸着能を十

はあまり使用されていない。特にガス処理用や水
処理用の分野では非常にわずかしか使われていな
い。その理由としては、具体的な用途における
種々の仕様に応じた成形が難しく、取り扱いにく
いことがあげられる。 On the other hand, carbon fiber, which is a type of carbon material, is used as a light and strong reinforcing material in the manufacture of various reinforced plastic moldings, but activated carbon fiber, which is made by activating this carbon fiber, also has sufficient adsorption capacity. Despite its availability, it is not widely used as an adsorbent. Especially in the fields of gas processing and water treatment, very few are used. The reason for this is that it is difficult to mold it according to various specifications for specific applications, and it is difficult to handle it.
ところで、通常の活性炭の使用において、粉末

面積が大きく、吸着速度が高いなど、有利な点が

そのため活性化して吸着剤として使用する場合、
前記のごとく吸着塔の形状や大きさなどに応じ
て、切断したり、形を整えたりする必要があり、
その際形状がくずれたり、繊維片が系外へ流出し
やすいなどの問題があり、非常に使いにくいとい
う欠点がある。 By the way, when using normal activated carbon, when using powdered activated carbon, the operation of extracting and separating the activated carbon is complicated, and the pressure loss is large.In addition, when using granular activated carbon, the pressure loss can be reduced by increasing the particle size to a certain extent. However, there are problems such as a decrease in the adsorption area and a decrease in the adsorption rate. However, unlike powdered or granular adsorbents, activated carbon fibers have many advantages, such as easy separation from the gas or liquid to be treated, a large surface area, and a high adsorption rate. . However, ordinary carbon fibers are often commercially available in shapes such as felt, thread, and cloth.
Therefore, when activated and used as an adsorbent,
As mentioned above, it is necessary to cut or shape it depending on the shape and size of the adsorption tower.
At that time, there are problems such as the shape being distorted and fiber pieces easily flowing out of the system, making it extremely difficult to use.
本発明は、以上のような観点から、吸着速度が
高く、そのままの形状で吸着塔内へ単に充填する
だけで使用できる、取り扱いの極めて容易な吸着
材としての活性炭素繊維成形物を提供することを
目的とするものである。 In view of the above, an object of the present invention is to provide an activated carbon fiber molded article as an adsorbent that has a high adsorption rate, can be used by simply filling it in an adsorption tower in its original shape, and is extremely easy to handle. The purpose is to
すなわち本発明は、複数本の繊維長0.5〜50mm
の活性炭素繊維が最大径３〜100mmの塊状にから
まり合つてなる吸着材及びその製造方法に関する
ものである。 That is, in the present invention, the length of multiple fibers is 0.5 to 50 mm.
The present invention relates to an adsorbent comprising activated carbon fibers entangled in a lump having a maximum diameter of 3 to 100 mm, and a method for producing the same.
以下に本発明について詳細に説明する。 The present invention will be explained in detail below.
本発明の吸着材を構成する活性炭素繊維として
は、アクリル系、ビニロン系、レーヨン系、ピツ
チ系あるいはリグニン系などのものがあげられ、
800〜2500℃で黒鉛化したもの、もしくは150〜
800℃程度で耐炎化あるいは炭素化したものが好
ましい。 The activated carbon fibers constituting the adsorbent of the present invention include acrylic, vinylon, rayon, pitch, and lignin fibers.
Graphitized at 800~2500℃ or 150~
Preferably, it is flame resistant or carbonized at about 800°C.
活性炭素繊維の繊維長としては、塊状に成形す
る際の各繊維間のからまりやすさの点から0.5〜
50mmにすることが必要である。 The fiber length of activated carbon fiber should be 0.5 to 0.5 to ensure ease of entanglement between each fiber when molded into a lump.
It is necessary to make it 50mm.
このとき、活性炭素繊維の繊維長が0.5mm未満
であれば、活性炭素繊維のからまりあいがなく、
吸着塔に充填するときに、あるいはガス又は水処
理等を行うときに、活性炭素繊維が飛散してしま
い、また、活性炭素繊維の繊維長が50mmを越える
と、塊状にならずヒモ状になり、このヒモ状では
活性炭素繊維そのものと変らず、吸着塔に充填す
るときに活性炭素繊維が折れ曲がつたり、細かく
切断したり、粉末化したりすることが避けられな
くなり、この範囲を外れると、吸着速度などの吸
着性能が劣ることになる。 At this time, if the fiber length of the activated carbon fibers is less than 0.5 mm, there will be no entanglement of the activated carbon fibers,
When filling an adsorption tower or performing gas or water treatment, activated carbon fibers will scatter, and if the fiber length of activated carbon fibers exceeds 50 mm, they will not form into lumps but strings. In this string form, it is no different from the activated carbon fiber itself, and when it is packed into an adsorption tower, it is inevitable that the activated carbon fiber will be bent, cut into small pieces, or turned into powder. , the adsorption performance such as adsorption speed will be inferior.
また、活性炭素繊維の太さとしては、直径で５
〜100ミクロン程度のものが吸着性能及び塊状物
の成形性の点から適当である。 In addition, the thickness of activated carbon fiber is 5 in diameter.
A diameter of about 100 microns is suitable from the viewpoint of adsorption performance and formability of lumps.
繊維塊としては最大直径が３〜100mmの球、楕
円球又は円板状のものが吸着処理操作の際の取り
扱いやすさの点から最も好ましい。 The fiber mass is most preferably in the form of a sphere, an ellipsoid, or a disc with a maximum diameter of 3 to 100 mm from the viewpoint of ease of handling during the adsorption treatment operation.
本発明の吸着材は、次に述べる手段により容易
に製造することができる。すなわち0.5〜50mmの
繊維長を有する短繊維状の活性炭素繊維を水など

流撹拌や羽根等による機械的撹拌によつて撹拌を
続ける。時間の経過とともに活性炭素短繊維が互
いにからまり合つて、最大直径が３〜100mmの塊
状成形物が生成する。この塊状の活性炭素繊維を
取り出し、吸着材として使用する。 The adsorbent of the present invention can be easily manufactured by the following method. In other words, activated carbon fibers in the form of short fibers with a fiber length of 0.5 to 50 mm are dispersed in a liquid such as water, and while the temperature of the liquid is maintained at a predetermined temperature in the range of 10 to 90°C, a water stream is created by blowing into a gas or the like. Continue stirring by stirring or mechanical stirring using a blade. Over time, the activated carbon short fibers become entangled with each other, producing a block-like molded product with a maximum diameter of 3 to 100 mm. This lump of activated carbon fiber is taken out and used as an adsorbent.
塊状に成形する際、賦活した活性炭素繊維を用
いれば、成形された塊状物をそのまま吸着剤とし

選択して行なえばよい。なお、吸着処理後の吸着
活性再賦活に際しても全く同様に実施することが
できる。 When molding into a lump, if activated activated carbon fibers are used, the molded lump can be used as an adsorbent as is, but if unactivated carbon fiber is molded, it may be activated after molding. Activation may be carried out by appropriately selecting a conventional activation method such as a chemical activation method or a gas activation method. Note that reactivation of adsorption activity after adsorption treatment can be carried out in exactly the same manner.

やすさの点から水の使用が最適である。 In addition to water, liquids for dispersing activated carbon fibers include
Although organic solvents such as ethylene glycol and alcohol can also be used, water is most suitable from the viewpoint of the properties of activated carbon fibers and ease of handling.
活性炭素繊維の分散液の撹拌方法としては、空

行われる撹拌などを適宜採用することができる。 Stirring methods for the activated carbon fiber dispersion include water jet agitation by blowing gas such as air or nitrogen, mechanical agitation using blades such as a turbine, fan turbine, propeller, or paddle, or a spherical rotating tank. As in a concrete mixer, a stirring method in which a baffle plate is built into the tank and the entire tank rotates can be used as appropriate.

It can be used to adsorb and remove trace organic substances such as humic acid. Further, the adsorbent of the present invention is extremely useful as an adsorbent for gas purification, for example, for adsorption and removal of malodorous substances.

Therefore, there is no need for complicated processing such as cutting or shaping of the material, which is required when conventional activated carbon fiber materials are used as adsorbents, and handling is extremely simple. Moreover, since the adsorbent of the present invention has a large surface area, the adsorption rate is high.
Moreover, the pressure loss is very small, and the air to be treated is
There is little clogging due to foreign substances contained in the liquid, and when the liquid becomes clogged, the foreign substances can be easily removed by vibration or flow.
