摘要：
A series of metal loaded zeolite catalysts (Pd/H-ZSM-5, Pd/H-BETA, Pt/H-ZSM-5, and Pt/H-BETA) were investigated for their activity and selectivity during oxidation of different chlorinated hydrocarbons, namely dichloromethane and trichloroethylene, at constant gas space velocity (15,000 h-1) and constant chlorohydrocarbon concentration (1,000 ppm in dry air). It was observed that the two noble metals played a major role in influencing the catalytic performance for complete oxidation of both chlorinated compounds. The acidic properties of the zeolite support in combination with increased oxygen activation owing to the noble metal were responsible for the high chlorocarbon destruction activity exhibited by this type of catalysts.
