丙烷脱氢制丙烯技术进展

Technologic Progress of Preparing Propene by Propane Dehydrogenation

丙烯是一种很有应用潜力的无色可燃气态烃。本文综述了丙烷脱氢制丙烯的国内外发展状况,对丙烷脱氢热力学进行了分析:因为该反应为一可逆、增分子、强吸热反应,所以必须采用选择性良好的催化剂,才有利于丙烷选择性的提高;对无机膜反应器中的丙烷脱氢及以氧气和二氧化碳作氧化剂的丙烷氧化脱氢几种丙烯制备方法进行了总结。

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.
