Propane-to-propene oxide oxidation was carried out at 673 and 703K and for different contact times on vanadium catalyst supported on mesoporous silica of SBA-3 structure in the presence of N2O as an oxidant. For comparison, direct propene epoxidation was also investigated. Vanadium catalysts for propane oxidation undergo deactivation with time on stream. It was noted that the higher the reaction temperature...
The surface structure of vanadium species supported on SiO 2 , Al 2 O 3 , TiO 2 , and MgO and the effect of these supports on the activity of vanadium catalysts for propylene to propylene oxide oxidation with N 2 O as an oxidant were studied using ultraviolet visible diffuse reflectance spectroscopy and Raman spectroscopy, infrared spectra (IR) of adsorbed reagents,...
