摘要/Abstract

摘要： Incorporation of strontium into V-Mo alumina-supported catalyst enhanced its performance (increased conversion and selectivity, decreased reducibility and improved stability) in propane oxydehydrogenation to propylene. 12.5% Sr loading was shown to be the optimum content to the V-Mo catalyst. The results were supported by various characterization techniques, namely, BET, XRD, SEM, FTIR and TPD.
