Abstract
The paper discusses one aspect of catalyst stability (i.e., deactivation by poisoning) and the concomitant effects on catalyst activity and selectivity in the destruction of chlorinated hydrocarbons. The study was initiated because nothing is documented of the effect of H2S or the other sulfurous poisons on the performance of catalysts in the specific application of oxidative destruction of chlorinated volatile organic compounds (VOCs). A chromia (Cr2O3) catalyst, commercially popular for the destruction of chlorinated hydrocarbons, was chosen for the study of H2S poisoning effects, which concentrated on the activity, selectivity, and stability trends of the catalyst to H2S. Study results indicate that poisoning of the catalyst by H2S brings about mixed effects. While activities generally decreased, the selectivities to HCl and chloroform became more favorable and the selectivity to CO2 decreased.
