Abstract

Catalytic dehydrogenation of propane has recently received considerable attention because of the increasing demand for propane. In this present work, the catalytic performances of layered nanowires of Mg 0.15V 2O 5.152.4H 2O with equal weight of either Al 2O 3 or SiO 2 were investigated in propane dehydrogenation and compared with the bulk commercial V 2O 5, at atmospheric pressure and temperature range of 500-600°C. Both dehydrogenation and cracking reactions products were obtained; which suggested sites of different relativities. The catalysts exhibited propylene, ethylene, ethane and methane as primary products. The highest propylene yield of 17% was obtained in the presence of Al 2O 3. The nanowire samples exhibited higher selectivity to propylene than bulk samples at similar level of propane conversions. For the nanowire samples, the conversion increased (1-3%) while selectivity to propylene decreased (96-87%). At low propane conversions (
