Research on Preparing Propylene by Propane Dehydrogenation

The development of preparing propene by propane dehydrogenation is outlined in this paper,including catalytic dehydrogenation,oxidative dehydrogenation and dehydrogenation in the membrane reactor.Although,catalytic dehydrogenation of propane has been commercialized,the performance of catalysts needs to be further improved.The catalytic systems and their main results of propane oxidative dehydrogenation to propylene are viewed.Compared with the traditional dehydrogenation,the membrane reactor has its advantages in propane dehydrogenation.If the activity and stability of catalysts for propane dehydrogenation and the hydrogen perm-selectivity of the membrane reactor can be further improved,the membrane reactor is a promising method for the dehydrogenation of propane.
