Abstract

Fluidizable catalysts for the oxygen-free oxidative dehydrogenation of alkanes to corresponding olefins. The catalysts comprise 10-20% by weight per total catalyst weight of one or more vanadium oxides (VO) such as VOas well as 1-5% by weight per total catalyst weight of niobium as a promoter. The dehydrogenation catalysts are mounted on an alumina support that is modified with lanthanum to stabilize bulk phase transformation of the alumina. Various methods of preparing and characterizing the catalysts as well as methods for the oxygen-free oxidative dehydrogenation of alkanes to corresponding olefins with improved alkane conversion and olefin selectivity are also disclosed.
