Abstract

The hydrodechlorination of mixtures of tetrachloroethylene (TTCE) andchlorobenzene (CBZ) over a supported palladium catalyst has been studied in this work. Experiments have been carried out in large excess of hydrogen at 250°C and 0.5 MPa. Inhibition effects have been found, being especially strong the effect of TTCE on the CBZ hydrodechlorination. Kinetic data were fitted to Langmuir-Hinselwood rate models, the best results being obtained supposing that adsorption of H2, CBZ and TTCE takes place in the same active sites.
