摘要：NOVELTY - The invention discloses the catalytic cleaning method of trichloroethylene. The method comprises the following steps: insufflating the humid air into waste gas containing trichloroethylene to carry out reaction at the existence of catalyst which is composed by carrier, rare metal, rare earth oxide and phosphorus acid; at humid air and low temperature, the trichloroethylene changed to carbon dioxide and hydrochloride, and the catalyst keeping active. The precious metal content in catalyst is few, and there is not polychlorocarbon byproduct, so the method is effective and environmental conservation.
