Catalytic Destruction of Chlorinated Volatile Organic Compounds

Abstract

This report gives test results for 14 different cation-modified zeolite catalysts, all of which were prepared in our laboratories. Three different dilute vapor phase feeds (trichloroethylene, carbon tetrachloride, and methylene chloride) were investigated in detail for catalytic destruction characteristics over a temperature range from 175-600 deg C. Long term catalyst thermal stability studies were carried out at high temperature (600 deg C), while deactivation by coking was investigated at temperatures as low as 175 deg C. It was found that the most active catalysts for destruction of One-carbon VOCs were cobalt exchanged Y-zeolites, while for two-carbon VOCs, the presence of chromium in the catalyst was highly desirable, preferably in the impregnated form. Thus the most versatile active catalyst for the destruction of mixed feeds was shown to be a cobalt exchanged, chromium impregnated Y-zeolite known as Co- Y/CA.
