Comparative kinetics study of the catalytic oxidation of benzene and its mono-halogenated derivatives over V$_{2}$O$_{5}$–WO$_{3}$/TiO$_{2}$ catalyst

The SCR-DeNOx commercial catalysts are reported as possible candidates to remove aromatic VOCs and NO$_{{x}}$ simultaneously. In this paper, we present the kinetic studies of the oxidation of benzene and its mono-halogenated derivatives over V$_{2}$O$_{5}$–WO$_{3}$/TiO$_{2}$ catalyst as typical high-dust SCR-DeNOx system. The kinetic investigation follows the influence of temperature on the conversion of aromatic VOCs to establish the apparent energy activation and dependence on between temperature and the effective constant rate of the catalytic oxidation reaction. The data shows that the catalytic oxidation process takes place after a combined kinetic mechanism, mass transport through pores—chemical transformation.
