PROBLEM TO BE SOLVED: To obtain an activated carbon molded body having high function as an oxidation catalyst at ordinary temp. or low temp. even in the case of a very low concn. of malodorous gas by carrying a specified amt. of a metal oxide on activated carbon obtd. through specified processes, adding a binder and molding them in a honeycomb shape. SOLUTION: Oxides of one or more kinds of metals selected from among Fe, Cr, Ni, Co, Mn, Zn, Cu, Mg and Ca are carried by 0.1-20wt.% on activated carbon obtd. by carbonizing carbonaceous stock, activating the resultant carbon in an atmosphere having <=15vol.% steam content and cooling it to <=300 deg.C in the atmosphere or activated carbon obtd. by treating activated carbon obtd. by the conventional method at >=500 deg.C in gaseous nitrogen and gaseous CO2 not contg. oxygen or steam and cooling the treated carbon to <=300 deg.C in the atmosphere. An org. binder is added by 1-50 pts.wt. to 100 pts.wt. of the activated carbon carrying the oxides and they are molded in a honeycomb shape. |
