Description of the Related Art Conventionally, as a method for removing exhaust gas and the like, efforts have been made to purify exhaust gas by using a catalyst such as platinum which can be oxidized and reduced, but it was not possible to partially purify exhaust gas. Activated carbon is obtained by carbonizing coconut grains or hard wood, and has a very good adsorbing power for gases and the like, but its use is limited because it is very expensive. There is a method of carbonizing small chips such as sawdust, but the yield was reduced because it was carbonized in the kiln. Since carbonization of sawdust and the like is fine particles, some processing was required. There was a lot of waste and ash, and it was very expensive. Trees are made up of trunks, roots, and leaves, but when steamed, they all become ash. However, among the trees, the trunk material is the most, and because it makes good charcoal, only the trunk is usually used as the raw material for charcoal-burning. Roots and branches had low commercial value, were easily turned into ash, and collapsed, so they had no value as charcoal.

い。EFFECTS OF THE INVENTION Grasses and leaves tend to turn into ash when carbonized, and have a role as a fertilizer in many cases, but they do not turn into ash because the grasses and leaves that are compressed intimately are carbonized using noncombustible gas. Since plant fibers have many voids and adsorption areas in advance, the adsorption effect is high. Grass and leaves are very easy to obtain because they use familiar fibers. It is very economical because it uses familiar fibers. Since fine fibers are reinforced with wire mesh etc., they have the same performance as hard carbon. Since reinforcing fibers and the like can be added or mixed, workability and the like are improved. Since it is formed into a predetermined shape in advance, the subsequent process is unnecessary. Since it uses plant fibers that are familiar to us rather than plant trunks or special ones, it does not destroy the natural environment.
