作为国内汽柴油的主要调和组分,催化裂化汽柴油的清洁改质问题是国内炼油化工企业汽柴油质量升级的关键,而加氢处理工艺是目前采用的主要升级途径。通过对比选择性加氢脱硫降烯烃工艺和加氢脱硫恢复辛烷值工艺的技术特点和适用条件,结合炼油化工企业的不同质量升级需求,讨论了企业较为适宜采用的技术,并指出在满足现有升级需求的同时应注意的后续发展问题。
As the main blending component of gasoline and diesel in China, the problem of cleaning and reforming FCC gasoline and diesel is the key to the quality upgrading of gasoline and diesel in domestic refineries and chemical enterprises, and the hydrotreating process is the main upgrade route adopted at present. By comparing the technical characteristics and applicable conditions of selective hydrodesulfurization and olefin reduction and hydrodesulfurization to recover octane number, the paper discusses the more appropriate technology for enterprises to adopt, combining with the requirements of different quality upgrading of refining and chemical enterprises, Follow-up development issues that need to be noticed while upgrading.
