Dehydrogenation of Propane over Rh-added V₂O₅/SiO₂ Catalysts Effect of the Presence of CO₂ and the Rh Addition on the Reaction

Abstract

The dehydrogenation of C₃H₈ and the reduction of CO₂ were carried out simultaneously using Rh-added V₂O₅/SiO₂ catalysts. The addition of Rh to V₂O₅/SiO0₂ and the presence of CO₂ in the reactant flow increased the yield of C₃H₆ at the steady state of the reaction. CO₂ may be utilized as an oxidant for the reaction and/or may be used to remove produced carbon by reverse Boudouard reaction. In particular, the addition of very small amount of Rh (0.1 wt%) was effective to increase the effect of CO₂ addition.
