Kinetic study of trichloroethylene combustion on exchanged zeolites catalysts

Abstract

In this paper is presented a kinetic study of the catalytic combustion of trichloroethylene (TCE) over Yzeolites exchanged with several cations. The catalysts, based on zeolite, were prepared by ion exchange and characterized by means of physico-chemical techniques and then tested under kinetic conditions. The kinetic results obtained were interpreted using kinetic models of power-law type and Eley–Rideal. The results obtained indicate that catalyst Y-Cr is more active than Y-Co catalyst. The greater activity of catalyst exchanged with Cr can be attributed to the higher acidity that presented these catalysts.
