The toluene hydrogenation performances of MO-and NiMo-A1203 hydrotreating catalysts are modified by vanadium deposited through HDM of the Vanadylporphyrin. Bulk deposited vanadium sulfide of mean VS 1 .l stoichiometry does not greatly affect the intrinsic performances of the initial catalysts but i
The oxidation of propane over V/AIPO4 with vanadium concentrations ranging from 0.2-15 wt.-% was investigated with regard to the dependence on temperature and partial pressures of oxygen and propane. Main products are propene and carbon oxides, while formation of C2-hydrocarbons, mainly ethene, occu
