Abstract

In this study, for the first time, MoO3/MgAl2O4 catalysts and their potassium-promoted forms were prepared and tested for oxidative dehydrogenation of propane. Catalysts were characterized with XRD, BET, NH3-TPD, TPR and XPS methods. Catalytic activity measurement was done with quartz microreactor between 450 and 550°C. It has been observed that the conversion of propane increased with temperature and total hydrocarbon selectivity increased with molybdenum oxide content. The acidity of catalysts decreased with potassium addition due to interaction with MoO3 sites. For this reason total hydrocarbon selectivity highly increased.

The conversion of propane increased with temperature and total hydrocarbon selectivity increased with molybdenum oxide content. Potassium addition suppressed the acidity of catalysts due to interaction with MoO3 sites. For this reason total hydrocarbon selectivity highly increased.
