摘　　要：综述了对正丁烷脱氢制备正丁烯的催化剂体系,包括有氧脱氢中钒基催化剂、钼酸盐系列和焦磷酸盐系列催化剂;催化脱氢中贵金属Pt系催化剂、以ZSM-5分子筛为载体的催化剂以及膜反应器。探讨了正丁烷脱氢动力学,并在Mars-van Krevlen和Eley-Rideal机理模型动力学基础上归纳了正丁烷氧化脱氢及直接脱氢的机理。讨论了正丁烷脱氢催化剂的影响因素,比较了各类催化剂的特点并对其进行展望,认为ZSM-5分子筛将可能成为正丁烷脱氢制正丁烯的新的研究热点。The series of catalysts for dehydrogention of n-butane to 1-butene, including oxidative dehydrogenation with vanadium-based, molybdate, metal pyrophosphate catalysts and catalytic dehydrogenation with Pt-based catalysts and ZSM-5 zeolite are reviewed, and the membrane reactor with catalysts is discussed. The kinetics for butane dehydrogenation, the reaction mechanism of n-butane oxydehydrogenation and direct dehydrogenation based on Mars-van Krevlen and Eley-Rideal kinetics are reviewed. The characteristics of several catalysts are compared and the catalyst ZSM-5 zeolite would likely be the reserch hotspot for n-butane dehydrogenation to 1-butene.
