Catalytic hydrolysis of CFC-12 over solid acid Ti(SO_4)_2

摘要

The catalytic hydrolysis of dichlorodifluoromethane （CFC-12） was investigated over solid acid Ti（SO4）2. The catalytic activity decreased with the calcination temperature. When space velocity was 6 1 h-1 g-cat-1. the CPC-12 conversion at 310C over Ti（SO4）2 calcined at 350C remained about 98.5% during 360 h on stream. and the selectivity to by-products remained zero. The findings enlarged the scope of traditional catalyst systems for the CFCs decomposition.
