摘要
随着社会经济的发展,对乙烯、丙烯和丁烯等低碳烯烃的需求量和性能要求日益提高。低碳烯烃的来源一般包括对石油烃类、天然气和煤炭进行深度化学加工三大途径。除已经比较成熟的蒸汽热裂解制低碳烯烃技术外,石油烃类催化裂解制低碳烯烃技术,由于催化剂的催化作用,具有裂解温度相对较低、能耗小、丙烯收率高的特点,是对蒸汽热裂解生产烯烃技术的有效补充。本文对C_(2)~C_(8)、石脑油以及重油等不同石油烃类催化裂解制低碳烯烃技术的研究和应用现状做了介绍,指出石油烃催化裂解制低碳烯烃新技术的研究开发应该引起研究机构重视。
With the development of social economy,the demand and performance of ethylene,propylene and butene are increasing.The sources of low-carbon olefins generally include 3 major ways of deep chemical processing of petroleum hydrocarbons,natural gas and coal.In addition to the relatively mature steam pyrolysis technology for producing low-carbon olefins,the catalytic cracking technology for producing low-carbon olefins from petroleum hydrocarbons has the characteristics of relatively low cracking temperature,low energy consumption and high propylene yield.It is an effective supplement to the steam pyrolysis technology for producing olefins.In this paper,research and application status of catalytic cracking of different petroleum hydrocarbons such as C_(2)~C_(8),naphtha and heavy oil to produce low carbon olefins was briefly introduced.The research and development of new technology for catalytic cracking of petroleum hydrocarbons to produce low-carbon olefins should arouse the attention of research institutions.
