Sol-gel vanadium-titanium-molybdenum mixed oxides for oxidative dehydrogenation of ethane

摘要

This paper reports about the application of the solution-sol-gel method for the elaboration of multicomponent oxide catalysts supported on TiO2-Mo3 gels.To increase the specific surface area of the gel treating of the precursors in supercritical conditions has been used.V-W-Sb-Bi-0 oxides supported on the obtained gels have been characterised,using DTA-DTG analysis XRD and BET method and tested in oxidative dehydrogenation(ODH)of ethane.The testing demonstrated good activity and very high selectivity to ethylene(up to 93%),where as the yield of ethylene achieved 80%.
