丙烷催化脱氢制丙烯Pt系催化剂研究进展

综述了近年来国内外主要的丙烷脱氢制丙烯工艺技术现状，详细介绍丙烷在Pt系催化剂上脱氢的反应机理、载体及助剂，简介了其他丙烷催化脱氢催化剂存在的问题及化学链脱氢技术的优势。不断优化Pt系催化剂，降低成本。减少催化剂中Pt含量的同时提高催化剂的稳定性以及开发非铂非铬环保型脱氢催化剂是今后的主要研究方向。

ADVANCES OF Pt CATALYSTS FOR PROPANE CATALYTIC DEHYDROGENATION TO PROPYLENE

The main technologies of propane dehydrogenation at home and abroad, the reaction mechanism of propane dehydrogenation on Pt catalyst, the support and the promoter of Pt catalyst were reviewed. The problems of other catalysts for propane dehydrogenation and the advantages of chemical looping dehydrogenation technology were briefly introduced. Pt catalyst was optimized continuously to reduce cost. The main research direction in the future is to improve the stability of catalyst while reducing Pt content and develop non-Platinum and non-Chromium environment-friendly dehydrogenation catalyst.
