Abstract

Catalytic total oxidation of selected chlorinated hydrocarbons utilizing several noble metal (Pt, Pd, Ru)‐based catalysts was studied. Chlorinated hydrocarbons used were trichloroethylene, dichloromethane, and chlorobenzene, alone or mixed with other hydrocarbons, such as toluene. Catalysts tested were both commercially available, manufactured by Degussa AG, Süd‐Chemie AG, Kataleuna GmbH, Chimet, Johnson Matthey, Prototech Co., etc., and new ones developed by Universities of Leiden in The Netherlands, Budapest in Hungary, and Wroclaw in Poland. Both forms of catalyst, sphere (particulate) and monolith, were used. Selection of the best catalyst(s) was made based on its activity, selectivity, and life. Apparent energies of activation for the reactions on these catalysts, using an empirical firstorder reaction rate, are also given.
