摘　　要：概述了目前已工业化的几种丙烷无氧脱氢制丙烯的技术,包括美国UOP公司的Olefl ex工艺、Lummus公司的Catofi n工艺、Krupp-Uhde公司的STAR工艺以及德国Linde-BASF公司的Linde工艺和Snamprogetti公司的FBD工艺。介绍了两种常用的丙烷无氧脱氢催化剂(Cr系和Pt系催化剂),简述了Cr系催化剂及其工艺,详述了Pt系催化剂的活性中心及脱氢机理及其改性的主要途径(加入助剂、改变催化剂载体和催化剂的制备方法等),并探讨了Pt系、Cr系催化剂的失活再生。最后对丙烷无氧脱氢反应及其催化剂的研究前景(包括反应机理、反应动力学、助剂的作用和催化剂的稳定性等)进行了展望。Several industrialized technologies for the anaerobic dehydrogenation of propane to propylene were reviewed.Among them,the Oleflex,Catofin,STAR,Linde and FBD technologies were developed by UOP company,Lummus company,Krupp-Uhde company,Linde-BASF company and Snamprogetti company,respectively.Two kinds of common catalysts（Pt-based and Cr-based） for the anaerobic dehydrogenation were introduced.The Cr-based catalysts and relative technologies were discussed briefly.The mechanism of the dehydrogenation over Pt-based catalysts,promoters,supports and preparation methods were investigated.The coking deactivation and regeneration of the two kinds of catalysts were also involved.The development trends for the propane dehydrogenation in future were presented.
