Abstract: Catalytic pyrolysis inherits advantages of conventional steam cracking and fluidized catalytic cracking，and shows good feed adaptability and high yields of light olefins. Processing technologies have been researched for a wide range of petroleum feedstocks. This paper summarizes the advances in catalytic pyrolysis. ZSM-5 zeolite，thermodynamic equilibrium limitation and kinetic reaction conditions are important influence factors and research interests for catalytic pyrolysis. Catalyst study is still the key point in developing catalytic pyrolysis processes，and thermodynamics and kinetics are effective methods to study reaction behavior.

Key words: catalytic pyrolysis, light olefins, ZSM-5 zeolite, thermodynamic equilibrium, kinetics

摘要： 对以石油路线生产低碳烯烃的催化裂解工艺进行了综述。催化裂解结合了传统蒸汽裂解和流化催化裂化的优势，表现出良好的原料适应性和较高的低碳烯烃产率，针对不同的石油裂解原料已经开展了相应工艺技术的研究。本文总结了目前催化裂解制低碳烯烃技术的研究进展，指出ZSM-5分子筛催化剂、热力学平衡限制和动力学反应条件是催化裂解反应过程中的重要影响因素和研究内容。催化剂研究仍是催化裂解工艺开发的重点，而热力学和动力学是研究反应规律的有效方法，这是今后实现石油烃类定向转化的研究方向。
