چکیده انگلیسی
The oxidative dehydrogenation of ethane to ethylene in the presence of CO2 has been carried out over a series of chromium oxide catalysts sonochemically supported on parent SAPO-34s with various Si content and LaAPSO-34(0.2). The variation of silicon content indicates that there is the optimum silicon content in Cr/SAPO-34(0.2) for the better catalytic activity. Doping SAPO-34(0.2) by lanthanum metal endows a most efficient applicable support for the selective oxidative dehydrogenation process. The superior performance amongst the various SAPO-34 supported catalysts was observed with Cr/LaAPSO-34(0.2), attributable to the higher surface area, more effective surface acidity and better Cr species dispersion.536
