Effect of the Reaction Bath Temperature in a Fixed-Bed Reactor for Oxidation of o-xylene over V2O5/TiO2 catalysts

Abstract

The effects of the reaction variables in the operation of a fixed-bed reactor for oxidation of o-xylene over V2O5/TiO2 catalysts were studied experimentally using a bench reactor. Reaction temperature, feed flow rate and feed concentration of o-xylene were found to have significant effects on the product distribution and the temperature profile in the reactor. Drastic enhancements of o-xylene oxidation reaction were observed at some conditions, which was ascribed to the effect of heat accumulated in the bed and indicated a possible way to increase the productivity in the industrial condition.
