Peculiarities of Dehydrogenation and Destruction of Propane in Transitional Catalytic Systems MeVO x (Me = La, Sm, Er)

Features of propane conversion in the presence of rare-earth metal vanadite and vanadate, both produced via solid-phase synthesis, are studied. It is shown that MeVO3 catalyzes mainly the propane cracking process to form methane and ethylene, while MeVO4 equally accelerates both cracking and dehydrogenation of propane. The thermal stability of MeVO4 in a hydrogen atmosphere is studied by a temperature-programmed reduction, while the MeVO3 stability in an oxidizing environment is studied by DTA. Energies of activation for the MeVO3 reduction and the MeVO4 oxidation are calculated using the Kissinger method.
