(Industrial Application Field) The present invention relates to a method for producing an activated carbon molded body. (Prior Art) Activated carbon used for gas adsorption is not limited to crushed carbon and granulated carbon, but also molded bodies with gas passages provided inside are used. Conventional activated carbon molded bodies are made by blending the raw material carbon as the main material and a binder and firing and activating the mixture, and some have ceramic material in the skeleton as a structure.
To manufacture such a product, raw coal, binder and ceramic material are first kneaded to form a shaped structure, for example by extrusion, and then this structure is carbonized and activated. Another manufacturing method is to make paper by mixing powdered activated carbon, activated carbon fibers, and pulp slurry as a binder to make a sheet of activated carbon paper, which is then molded into a structure. (Problem to be Solved by the Invention) In the conventional manufacturing method as described above, the former has limitations in the shape due to the extrusion molding technique and may not be able to produce a desired shape, and also requires a mold. However, there is a drawback that the processing cost is high due to the long extrusion time. Furthermore, since the latter is an activated carbon paper, it is not possible to obtain the desired paper strength, and it is difficult to form a desired shape due to the lack of freedom in molding.Furthermore, the peeling and falling off of the activated carbon is inevitable, resulting in poor quality. to degrade. Note that since pulp or the like is used, the adsorption capacity is insufficient. (Means for solving the problem) The present invention is intended to solve the above problem. The method for producing an activated carbon molded body of the present invention is to mix raw materials such as coconut shell charcoal or anthracite powder, rayon, pulp or sawdust, caking agent, and glass fiber to form a slurry, form the slurry into a sheet using a paper machine, and then calender. It is then processed to densify it and molded into a structure with a plurality of parallel gas passages therein, which is then fired and activated. (Function) In the manufacturing method of the present invention, the material before molding is in the form of a high-density sheet, and the skeleton material is mixed in the form of fibers, so the sheet state is easily maintained, and the material can be easily maintained in a sheet state, such as by embossing, bending, etc. It is easy to process and form
Freely shaped structures can be formed. (Example) An example of the present invention will be described. For example, the honeycomb-shaped activated carbon molded body 1 shown in the figure is activated carbon 2 in which coal powder is activated as the main material.
In addition, it is a molded body having a vitreous skeleton material 3, and is a structure having a plurality of parallel gas passages 4 inside. This is manufactured as follows. Raw materials: 30-50 parts of coconut shell charcoal or anthracite powder, 5-45 parts of rayon, 10-50 parts of pulp or sawdust, 10 parts of binder.
Prepare a slurry containing 15 parts of glass fiber, run it on a paper machine to form a sheet, calender it to make it densified, and then stamp or bend it to form multiple parallel gas passages. 4
into a structure formed inside. This molded product is fired and activated, but this process is performed on the raw material of the molded product,
For example, at a temperature of 920 to 1200℃ for a time so that it conforms to the shape and the glass fibers melt and solidify to form a skeleton.
Keep for 15-20 minutes. In this way, an activated carbon molded body having a vitreous skeleton is obtained. According to an experimental example, the activated carbon molded body of the present invention obtained by the manufacturing method of the present invention is compared with a conventional activated carbon molded body having the same structure as shown in the following table.

(Effects) In the manufacturing method of the present invention, a highly densified sheet-like structure containing a fibrous skeleton is molded to form a honeycomb-like structure having a large number of gas passages. , molding is extremely easy, and the shape of the structure can be freely selected. In this way, it is possible to easily form a structure with a thin wall, a large number of gas passages, a large adsorption surface area, and a high adsorption efficiency.
