Demand for propene as a petrochemical building block keeps growing, while its availability has been decreased by the adoption of shale gas resources, among others. Efforts to optimize its production by conventional means (including modified fluid catalytic cracking) and new on-purpose production technologies (including ethene to propene (ETP) and olefin cracking) are being pursued. This work reviews the progress made on olefin conversion processes, including the ETP reaction, which is still under development, and the cracking of butenes and higher olefins (C₅–C₈). The factors analyzed include the catalytic performance of different zeolite materials and their modifications to increase catalyst stability, yield, and selectivity to propene, as well as the effect of operating conditions, reaction thermodynamics, and mechanisms involved. The work is complemented by a survey of commercial technologies and developments on olefin conversion processes.

对丙烯作为石化产品的需求不断增长，但由于页岩气资源的利用等原因，丙烯的可用性已经下降。正在努力通过常规手段（包括改进的流化催化裂化）和新的有针对性的生产技术（包括乙烯制丙烯（ETP）和烯烃裂化）优化其生产。这项工作回顾了烯烃转化工艺方面的进展，包括仍在开发中的ETP反应以及丁烯和高级烯烃的裂解（C ₅ –C ₈）。分析的因素包括不同沸石材料的催化性能及其对提高催化剂稳定性，产率和对丙烯的选择性的改性，以及操作条件，反应热力学和所涉及机理的影响。这项工作得到了对烯烃转化工艺的商业技术和发展的调查的补充。
