提高柴油十六烷值的FC-18催化剂研制开发

The Development of FC-18 Catalyst for Diesel Cetane Improvement

随着催化裂化技术的发展 ,产生了大量的质量较差、十六烷值低的催化柴油 ,需进一步处理来满足清洁柴油指标要求。FC - 1 8催化剂是抚顺石油化工研究院新近开发的一种改善劣质柴油 (如催化柴油 )质量的加氢处理催化剂。开发该催化剂的宗旨是通过控制催化柴油中芳烃开环而不发生进一步的裂化反应 ,在传统的加氢处理反应条件下 ,进行加氢脱硫、加氢脱氮 ,大幅度提高柴油十六烷值来达到既大幅度提高产品十六烷值 ,又能保证较高的柴油收率的目的。在通常情况下 ,FC - 1 8催化剂能够提高柴油十六烷值 1 2个单位 ,柴油收率大于 95 %。

The development of FCC results in a large quantity of low quality LCO which need further treatment to meet the product specifications. FC-18 catalyst is a novel hydrotreating catalyst for upgrading low quality diesel distillates (such as FCC diesel) by Fushun Research Institute of Petroleum and Petrochemicals, SINOPEC. It can perform HDS, HDN, simultaneously greatly improve product cetane number. The task of improving product cetane number is fulfilled by using a new type of catalyst FC-18 under nearly the same operating conditions of hydrotreating process. The purpose of this catalyst development is to control the reaction to the step of ring of aromatics opening without cracking to greatly increase the product CN and maintain high diesel distillate yields. In most cases FC-18 catalyst can increase the product CN more than 12 units and maintain the diesel distillate yields higher than 95%.
