摘要

概述了工业化丙烷脱氢工艺专利技术、热力学特征及反应机理。丙烷脱氢工艺使用的催化剂为铂系和铬系催化剂，针对这2类催化剂的优缺点分别从载体类型和助剂选择的角度综述了催化剂的研究进展，并对催化剂结焦问题进行了分析。

Abstract

The patented technologies,thermodynamic characteristics and reaction mechanisms of the industrial propane dehydrogenation (PDH) process are outlined in this paper.The Pt-series or Cr-series catalysts are used for PDH process.The advances of catalysts are reviewed from the type of carriers and the selection of auxiliaries respectively according to the advantages and shortages of these two series catalysts,and the coking problem of catalysts is analyzed.
