Abstract

The reaction of chlorine with γ-alumina was studied in the temperature range 300-1070 K by thermogravimetry and also by pulse and volumetric adsorption methods. An exclusively surface reaction was observed at 500-800 K, resulting in the consumption of chlorine and the formation of oxygen, which was detected by a gas chromatography-coupled pulse reactor. This oxygen-chlorine exchange on the surface led to a weight increase, as found in thermogravimetric experiments. As the formation of AlCl3 or AlOCl is not favoured in this temperature range for thermodynamic reasons, the observed reaction can only take place on a surface possessing excess energy. The extent of the oxygen-chlorine exchange increases with increasing temperature.
