CATALYST AND CATALYTIC OXIDATION-DEOXIDATION METHOD FOR UNSATURATED HYDROCARBON-CONTAINING GAS

Provided a catalyst, and a catalytic oxidation-deoxidation method for an unsaturated hydrocarbon-containing gas using the catalyst. The catalyst comprises a carrier as well as an active component, a first co-agent component, and a second co-agent component loaded on the carrier respectively, wherein the active component is one or more selected from the group consisting of oxides of Pt, Pd, Ru, Rh, Ag and Ir; the first co-agent component comprises one or more selected from the group consisting of a rare earth metal element, a group IVB metal element and a group VIII metal element; and the second co-agent component comprises one or more selected from the group consisting of an alkali metal element and an alkaline earth metal element. The deoxidation method using the catalyst obviates the need to add a reducing gas such as H2, allows hydrocarbons to react directly with oxygen to produce CO2 and H2O, achieves the goal of deoxidating a hydrocarbon-containing tail gas, and can prevent the generation of carbon deposits.
