Preparation, Characterization, and Oxidative Dehydrogenation of C₃H₈ with CO₂ of V-Cr/SBA-15/Al₂O₃/FeCrAl Metal Monolithic Catalysts

Abstract:

A series of V-Cr/SBA-15/Al₂O₃/FeCrAl metal monolithic catalysts with V content of 10wt% and Cr contents from 0 to 12.5wt% were prepared. The structure of the catalysts was characterized using XRD, XPS and TPR techniques. The catalytic activity for oxidative dehydrogenation (ODH) of propane with CO₂ was evaluated. The results indicate that the mesoporous structure of SBA-15 was retained after vanadium and chromium incorporation and the vanadium species were well dispersed. The V-Cr/SBA-15/Al₂O₃/FeCrAl catalyst with 10wt% V and 10 wt% Cr exhibited the best activity with a propane conversion of 49.9% and a propylene selectivity of 86.5% at 650 °C.
