CATALYST FOR DECOMPOSING VOLATILE ORGANOCHLORINE COMPOUND

摘要

PURPOSE:To provide a catalyst capable of efficiently decomposing a volatile organochlorine compd. in the coexistence of steam and oxygen and keeping activity over a long period of time by supporting a cocatalyst component and a main catalytically active metal component on the surface layer of a carrier. CONSTITUTION:A catalyst is obtained by supporting at least one of a component selected from the group consisting of platinum, palladium and ruthenium on the surface layer of a carrier based on titania as a main catalytically active metal component and further supporting a boron oxide thereon as a cocatalyst component and the supporting amt. of the main catalytically active metal component is 0.1-2wt.% of the catalyst in terms of metal and that of the cocatalyst component is 1-3wt.% of the catalyst as diboron trioxide.
