摘要

A comparative study of hydrodechlorination of dichlorodifluoromethane,carbon tetrachloride and 1,2-dichloroethane over alumina-supported Pd-Pt catalysts showed several interesting features in the catalytic behavior.Platinum,the metal which binds chlorine and chlorine-containing organic intermediate species less strongly than palladium is a better catalyst in CCl_4 hydrodechlorination.However,in hydrodechlorinations of CC1_2F_2 and 1,2-dichloroethane platinum offers too weak binding with reaction species,and in effect,Pd/Al_2O_3 shows a better catalytic performance than Pt/Al_2O_3.Nevertheless,this positive behavior of Pd/Al_2O_3 can still be improved by doping it with small amounts of platinum.The formation of mixed Pd-Pt ensembles leads to an enhancement of the overall activity and selectivity for partial hydrodehalogenation.Temperature-programmed hydrogenation (TPH) of deposits accumulated on the catalysts during hydrodechlorination confirms a better resistance of platinum against carbiding.In the case of Pd/Al_2O_3 and Pd-Pt/Al_2O_3 catalysts,massive amounts of coke (and chlorine) were found after CCl_4 reaction.
