Advances in the promoters of Pt-based catalysts for propane dehydrogenation

铂基催化剂用于丙烷催化脱氢的主要缺点是稳定性差、选择性低,通过添加助剂可以大大改善该催化剂的脱氢性能。针对催化剂助剂,综述了铂基丙烷脱氢催化剂的研究现状,分别介绍了碱金属、碱土金属、稀土金属和过渡金属作为助剂对铂基催化剂的影响,探讨了所添加助剂的作用机制,并对铂基催化剂研究前景进行了展望。

Platinum-based catalysts for propane dehydrogenation have problems of poor long-term stability and low selectivity. The performance of the dehydrogenation catalysts can be greatly improved by adding additives. The recent research progress in the platinum-based catalysts promoters and the action mechanism are reviewed in this paper. The effects of alkali metals, alkaline-earth metals, rare earth metals and transition metals as promoters on the Pt-based catalysts for propane dehydrogenation are summarized. The perspective for future research of the Pt-based catalysts for orooane dehydrogenation is also presented.
