CATALYST FOR TREATING ORGANOCHLORINE COMPOUND

摘要

PURPOSE:To provide a catalyst capable of efficiently decomposing an organochlorine compd. in the presence of air and water and capable of keeping activity for a long period of time. CONSTITUTION:A boria-alumina compsn. wherein boria content is 5-15wt.% as B2O3 and a specific surface area calculated by a nitrogen gas adsorbing method is 50m<2>/g or more and a crystal structure due to X-ray diffraction is an aluminum borate structure is used as a carrier. A catalyst for treating an organochlorine compd. is mainly constituted of this carrier and a noble metal being an active metal or a noble metal and a transition metal and contains the active metal in an amt. of 0.1-5% by wt. of the catalyst.
