Abstract

The photocatalytic oxidation of toluene in the gas phase using various TiO 2-based catalysts was studied. Five forms of TiO 2 were tested, i.e., TiO 2, TiO 2-Pt, TiO 2-Fe, TiO 2-Ce, and TiO 2 (isopropoxide). Toluene conversion followed the same profile for all catalysts, i.e., went through a maximum and then decreased with increasing toluene inlet concentration. A Langmuir-Hinshelwood rate expression was used to fit the experimental data and the reaction rate and adsorption constants were estimated for each catalyst. This is an abstract of a paper presented at the 7th European Congress of Chemical Engineering-7 and 19th International Congress of Chemical and Process Engineering CHISA 2010 (Prague, Czech Republic 8/28/2010-9/1/2010).
