Abstract
Abstract The gas-phase oxidation of o -xylene over a commercial V 2 O 5 -TiO 2 catalyst was studied in fixed bed non-isothermal reactor. The experiments were carried out at initial o -xylene concentrations which differed greatly from each other. The following reaction network was suggested. It is suggested to use the Langmuir-Hinshelwood kinetic model in which a surface reaction between o -xylene and oxygen, chemisorbed on separate active centres, is the limiting step. It seems that the redox model is not adequate for the kinetic description of o -xylene oxidation.
