<P>PROBLEM TO BE SOLVED: To decrease the amount of a binder to be used when using a plural kinds of activated carbons. <P>SOLUTION: In a pre-mixing process S1, a material containing 100 pts.wt. of at least one kind of activated carbon (11) selected from activated carbon having an average particle diameter D1 and a fibrous activated carbon having an average fiber diameter D2, and 7-70 pts.wt. of a solidified thermoplastic binder (12) having an average particle diameter of D3 is mixed. In a process S2 for adding the second activated carbon, the mixture (20) prepared in the pre-mixing process S1 is added with at least 500-10,000 pts.wt. of the second activated carbon (21) having the average particle diameter 50-500 μm (D4, provided that D4>D1, D4>D2, D4>D3). In a heating and mixing process S3, a mixture (30) added at least with the second activated carbon (21) is heated to a temperature above the temperature of the softening point of the binder (12) and at which the binder (12) does not become fired to be mixed. In a process S4 for producing granular activated carbon, the granular activated carbon is produced by crushing a mixture (40) after completion of the process S3 for heating and mixing. <P>COPYRIGHT: (C)2013,JPO&INPIT |
