제목 Dehydrogenation of Propane using CO2 as oxidant over CrOX supported sillica catalysts
초록 Oxidative dehydrogenation of propane was studied intensively over Cr supported silica catalysts by using CO2 as a soft oxidant. In the dehydrogenation of propane with CO2, different Cr loadings were investigated with varying CO2 flows. Even the loadings of chromium ranged from 1 to 11 wt % showed very high surface areas due to the TUD-1 type support which had warm-hole type mesoporosity. The present catalysts showed high activity (20%) and stability even after 8 hours of reaction. The ratio of Cr6+ and Cr3+ seemed to be the major control factor for the high activity. Alkali and alkaline earth metal could play a role as a promoter to activate CO2 molecule. The present study is focusing on the role of CO2 as well as promotional effect of alkali and alkaline earth metals, which was expected to give  the enhancement of CO2 conversion by altering the acid base properties of the catalyst and stabilizing the redox nature.
