Catalytic total oxidation of some selected chlorinated hydrocarbons is stud
ied with several Pt-based catalysts. Chlorinated hydrocarbons used have bee
n ethyl chloride, trichloroethylene and dichloromethane, alone or mixed wit
h some hydrocarbons, such as toluene. Eighteen different catalysts have bee
n tested from eight different manufacturers (Degussa AG, Sud-Chemie AG, Kat
aleuna GmbH, Chimet, Johnson Matthey, Prototech Co.,...) and from three res
earch institutions (Universities of Leiden (NL) and Wroclaw (PL) and Spanis
h CSIC-ICP). Catalysts both in the form of spheres (particulates) and of mo
noliths are used. Selection of the best catalyst(s) is made based on their
activity, selectivity and life. Apparent energies of activation for these r
eactions on these catalysts, using an empirical first-order reaction rate,
are given. There are interesting or noticeable differences in activity and
selectivity among the tested Pt-based catalysts. In overall they are not so
active as the chromia and vanadia-based catalysts but they have an high li
fe, reason why they can be recommended for this application. (C) 2000 Elsev
