Abstract
A method for producing propylene (CH) via oxidative dehydrogenation (ODH) of propane includes introducing a propane-containing feed gas stream into a reactor containing an alumina-supported GaO/LaOcatalyst comprising GaOparticles at least partially disposed on surfaces of a matrix comprising rough and irregular-sized LaOand alumina particles; passing the propane-containing feed gas stream through the reactor in contact with the alumina supported GaO/LaOcatalyst at a temperature of 500 to 600° C. to convert at least a portion of the propane to propylene (CH) and produce a propylene-containing gas stream leaving the reactor; and separating the propylene from the propylene-containing gas stream. The method has a propane conversion of up to 95% based on an initial weight of the propane in the propane-containing feed gas stream, and a propylene yield of up to 60% based on the propane conversion.
