Özet:

 

V22_{2}O55_{5} and K22_{2}O-V22_{2}O55_{5} impregnated MgAl22_{2}O44_{4} catalysts were prepared and tested for the oxidative dehydrogenation of propane. The as-synthesized catalysts were characterized by using the XRD, BET, NH33_{3}-TPD, TPR, and XPS methods. The catalytic tests were performed in a fixed bed tubular quartz reactor system between 450 and 550 ∘∘^{\circ}C. It was observed that the conversion of propane increased but hydrocarbon selectivity decreased with increasing temperature over the V22_{2}O55_{5}/MgAl22_{2}O44_{4} catalysts. The BET surface area values and surface acidities decreased upon potassium addition for the K-V22_{2}O55_{5}/MgAl22_{2}O44_{4} catalysts, which resulted in a drastic drop in the conversion values obtained. The propylene and total hydrocarbon selectivities increased with increasing temperature.
