Dehydrogenation of Ethylbenzene over Promoted Vanadium Oxide Catalyst with Carbon Dioxide: From laboratory to pilot-scale test

초록

Alumina supported binary vanadium-antimony oxides show enhanced catalytic activity and especially increased on-stream stability in the ethylbenzene dehydrogenation reaction in the presence of CO2 compared with VOx/Al2O3 catalyst. 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.
