PURPOSE:To produce a high capacity carbon material showing high decomposition properties to inorg. and org. substances such as hydrogen peroxide, hydrazine or the like by subjecting a carbonaceous material containing at least a predetermined amt. of oxygen to heat treatment in an oxidizable gas atmosphere. CONSTITUTION:A high capacity carbon material is produced by subjecting a carbonaceous material containing at least 4wt.% of oxygen to heat treatment in an oxidizable gas atmosphere. In the heat treatment of the carbonaceous material in the oxidizable gas atmosphere, it is extremely important that the carbonaceous material contains 4wt.% or more of oxygen in order to produce a highly active carbon material. Even when a carbonaceous material with oxygen content of below 4wt.% is heat-treated in the oxidizable gas atmosphere, the highly active carbon material having decomposition capacity to COD source water quality is not obtained. Therefore, the carbonaceous material with oxygen content of below 4wt.% is subjected to oxidizing treatment to be enhanced to at least 4wt.% in oxygen content before heat treatment. |
