Title
Catalysts based on pillared clays for the oxidation of chlorobenzene
Abstract

•Pd and Pt/alumina pillared clay catalysts were studied in chlorobencene combustion.•Formation of CO2 and small quantities of CO, PhClx and coke were observed.•The platinum phase catalyst was more chlorinated than palladium.•PhClx formation is affected by the metal loading and the metal chlorinated.

The aim of this work was to reveal the main factors which affect the oxidation of chlorobenzene (PhCl) over palladium and platinum supported on alumina pillared clays. The catalysts were prepared by wet impregnation of an alumina-pillared montmorillonite (Al-PILC) with palladium and platinum solutions and characterized by several physicochemical techniques before and after the catalytic tests. During oxidation of PhCl over the catalysts, the formation of carbon dioxide along with small quantities of carbon monoxide, PhClx and coke was found. The nature of the supported metal, the temperature, the metal loading, the support, and the time on stream, are factors affecting the combustion of PhCl.
