Abstract

The aim of this work was to investigate features of propane conversion in the presence of samarium, lanthanum, europium vanadate and samarium, lanthanum, europium vanadite. The conversion of propane was studied in the presence of samarium, lanthanum, europium vanadate and samarium, lanthanum, europium vanadite synthesized by solid-phase method. MeVO4 (Me=La, Sm, Eu) crystallized in the zircon structural type, while MeVO3 (Me=La, Sm, Eu) had a perovskite-like structure It was shown that MeVO3 (Me=La, Sm, Eu) catalyzes mainly the process of propane cracking to form methane and ethylene, and MeVO4 (Me=La, Sm, Eu) equally accelerates both cracking and the dehydrogenation of propane.

Keywords: Dehydrogenation, propylene, rare-earth vanadates, cracking, light olefins.
