Oxidative dehydrogenation of propane has been studied on molybdena deposited on SiO2, Al2O3, TiO2, and MgO. The catalytic performance depended on the support nature, the selectivity to propene at iso-conversion decreasing in the sequence: MoOx/SiO2 >MoOx/Al2O3 ~ MoOx/TiO2 > MoOx/MgO. Introduction of the K, Cr , Ni and V additives to MoOx/SiO2 and Cr to MoOx/MgO catalysts led to the increase of the total activity. The increase of the selectivity to propene was observed for the Cr and Ni additives, whereas the K and V in the MoOx/SiO2 catalysts decreased the selectivity (K and higher amounts of V), or did not affect it (lower amounts of vanadium).
