摘要：
A catalytic purifying method for a waste gas containing trichloroethylene is provided, which comprises introducing wet air into the waste gas to carry out reactions in the presence of a catalyst. The catalyst comprises a carrier stable in wet air, with rare metals, rare earth metals and phosphoric acid supported thereon. By the present method, the trichloroethylene contained in waste gas can be stably converted into CO 2 and HCl in wet air at a lower reaction temperature and in the presence of an oxidation-decomposition catalyst for a long time, while the activity of the catalyst is not decreased. The lower amount of rare metal makes it is possible to remove hydrocarbons containing chlorine in waste gas in a very economic way, and no byproducts and second pollution are generated. Therefore the present method is very effective for treating waste gas containing chlorine hydrocarbons, and can be used widely in environmental protection.
