摘要
传统的石油炼制和石油化工生产过程中一般都副产的大量碳四,其主要来自炼油厂催化裂化和烯烃厂蒸汽裂解的副产碳四,最近几年新建的百万吨级的蒸汽热裂解制乙烯装置以及新开发的由甲醇经过催化反应生成乙烯、丙烯为主的轻烯烃产品的新工艺、新技术的兴起,也使得副产碳四烃产量进一步增加,因此,合理利用碳四资源已成为亟待解决的问题,也是提高炼化、煤化工等企业经济效益的一个重要手段。本文主要介绍了目前碳四烃的来源、利用状况以及近年来新开发的工艺技术的进展。
Traditional oil refining and petrochemical production process generally by-product C4 Hydrocarbon, It mainly from the refinery catalytic cracking and olefin plant steam cracking by-product C4 Hydrocarbon, In recent years new megaton ethylene steam cracking device and the new development of generated by methanol through catalytic reaction light olefin products, mainly ethylene, propylene, the rise of new techniques, new technologies, the by-product C4 hydrocarbon yield increase, therefore, reasonable utilization of C4 hydrocarbon resources has become urgent to solve the problem, but also an important means to improve the economic benefits of petrochemical, coal chemical enterprises. This paper mainly introduces the C4 hydrocarbon source, as well as the progress of the new development of the technology in recent years.
