Technologic Progress of Preparing Propene by Propane Dehydrogenation

Propene is a colorless combustible unsaturated gaseous hydrocarbon. Domestic and foreign development of preparing propene by propane dehydrogenation is outlined in this paper. Thermodynamics of propane dehydrogenation is analysed and it is reported that the reaction is reversible,moleculeincreasing and intensely thermonegative;catalyst of good selectivity must be adopted in order to increase propane selectivity. Several methods of preparing propane are summarized, which include propane dehydrogenation in membrane reactor and oxidative dehydrogenation where oxygen and carbon dioxide are used as oxidant.
