摘要：

The development of a two bed catalytic system, consisting of an activated Al2O3 guard catalyst and a bimetallic Pd,Pt/Al2O3 oxidation catalyst, is described. The catalysts proved to be highly active and resistant to chlorinated hydrocarbons, which are well-known catalyst poisons. Based on the good results of pilot tests a big scale unit was built for the purification of an off-gas stream (up to 15,000 Nm3/h) coming from an industrial vinyl chloride manufacturing plant. After meanwhile 12,000 hours on stream the catalytic system is still operating with excellent performance. Estimates for the application described show that the catalytic process has a significant economical and technical benefit compared to the conventional thermal incineration.
