CATALYST FOR OXIDATION OF UNBURNED HYDROCARBON IN WASTE GAS

摘要

PROBLEM TO BE SOLVED: To obtain a catalyst for the oxidation of unburned hydrocarbons in waste gas containing excess oxygen as a high durability catalyst whose performance is not deteriorated over a long period of time even when SOx is contained in waste gas to be treated. SOLUTION: Platinum and palladium are supported on a titania carrier to obtain the objective catalyst for the oxidation of unburned hydrocarbons in waste gas containing excess oxygen and optionally containing SOx. Platinum and palladium are supported on a zirconia carrier to obtain the objective catalyst for the oxidation of unburned hydrocarbons in waste gas containing excess oxygen and SOx.
