摘　　要：概述了丙烷芳构化技术的发展历程、催化剂研究现状,分析了丙烷芳构化反应的热力学和动力学特性,汇总和比较了丙烷芳构化催化剂的催化性能评价结果。综述认为,丙烷芳构化反应常用HZSM-5分子筛催化剂,催化剂改性研究集中于分子筛本体和分子筛负载改性等,通过调节催化剂酸量和酸强度,调变催化剂晶粒尺寸、织构性质以及改性物种电子环境,抑制丙烷裂解以及对C1~C2的选择,促使聚合、环化和氢转移反应发生,促进烯烃的芳构化;改变反应体系的条件和共芳构化组分,结合膜分离等条件,也可以提高丙烷转化率和芳烃选择性。The development of propane aromatization technology and the research status of catalyst were summarized.The thermodynamic and kinetic characteristics of propane aromatization were analyzed.The results of catalytic performance evaluation of propane aromatization catalysts were summarized and compared.It was concluded that HZSM-5 molecular sieve catalyst was commonly used in the aromatization of propane,and the modification of catalyst focused on the modification of molecular sieve bulk and molecular sieve load.By adjusting the acid content and acid strength of the catalyst,adjusting the grain size and texture properties of the catalyst and the electronic environment of the modified species,propane cracking and the selectivity of C1~C2 were inhibited.Polymerization,cyclization and hydrogen transfer reactions were promoted to improve the aromatization of olefin.The conversion of propane and aromatics selectivity were improved by changing the conditions of the reaction system and the co-aromatization components combined with membrane separation.
