Abstract
In the presence of CO2 compared with VOx catalyst, alumina supported binary vanadium-antimony oxide catalysts show enhanced catalytic activity and especially increased on-stream stability in the ethylbenzene (EB) dehydrogenation reaction. Addition of antimony increases dispersion of active VOx component and redox properties of the systems and derives a new efficient mixed V-Sb oxide phase with the composition of V1.1Sb0.9O4. The effects of reaction temperature, ethylbenzene-to-CO2 ratio, size of catalyst particle were also studied in large-scale reaction, and the information for scale-up of the process was obtained.
