The gas-phase oxidation of o-xylene over a commercial V205-Ti02 catalyst was studied in tied 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.
Samples of the V 2 O 5 /TiO 2 system were prepared by the sol-gel method and calcined at different temperatures. Surface species of vanadium, their dispersion, as well as the structural evolution of the system were analysed by XRD, Raman, EPR, and XPS techniques. The results of XRD showed the evolut
