Decomposition treatment of fluorocarbon

Abstract

Abstract PURPOSE:To decompose a gaseous fluorocarbon which contains chlorofluorocarbon or hydrofluorocarbon at high efficiency by fringing the gas into contact to a catalyst under conditions of temp. and space velocity in specified ranges. CONSTITUTION:The catalyst consists of a carrier and elements selected from Pt, Rh, Pb, Ru, Mn, Cu, Cr, and Fe or oxides of these, deposited on the carrier. The gas which contains chlorofluorocarbon or hydrofluorocarbon is made to contact to the catalyst above described under conditions of >=200 deg.C and <=50000 (H<-1>) space velocity to decompose chlorofluorocarbon or hydrofluorocarbon. As for the carrier of the catalyst, it is preferable to use a honeycomb-type monolithic body having a through hole with <=30mm effective diameter and >=50% porosity.
