PURPOSE: To completely oxidize a hydrocarbon or aliphatic alcohol by forming an activated PdZr oxide catalyst and PdZrO2 precipitation catalyst composed of an amorphous or crystal alloy and expressed by a specific formula. CONSTITUTION: The activated catalyst expressed by the general formula, Pdx (ZrOz )y (in the formula, (x) represents integers of 1-99, (y) represents the difference of (x) from 100 and (z) represents 0.5-2) is formed. The catalyst is obtained by the activation treatment of the alloy expressed by a general formula, Pdx Zry (in the formula, each of (x) and (y) is the same as that in the said general formula), in a reaction body-containing gas or an oxygen-containing gas at 150-350 deg.C. Carbon monoxide, a hydrocarbon and an aliphatic alcohol are completely oxidized by the reaction in the presence of the catalyst in the oxygen- containing gas in the condition of room temp. to 350 deg.C and a normal pressure to 10 bar. |
