| 摘 要： | Due to increasing enthusiasm for environmental preservation, the synthesis ofchlorofluorocarbons (CFCs) alternatives and the decomposition of existing CFCs havebeen two hot topics since the production and utilization of CFCs are banned by manycountries. The former has been well carried out while the latter was rarely reported inChina. Among a dozen of decomposition approaches. catalytic hydrolysis is verypromising because of simple processes, requiring mild conditions, dioxins free and the…

| Abstract: | The catalytic hydrolysis of dichlorodifluoromethane (CFC-12) was investigated over solid acid Ti(SO_4)_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(SO_4)_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. |
