SulfrZol(R)54硫化剂在2Mt/a加氢装置应用

摘要

he SulfrZol? 54 pre-sulfiding agent was first tried in a 2.0 MM TPY hydrogenation unit of a petrochemical company. The commercial application results indicate that the SulfrZol? Pre-sulfiding agent can meet the pre-sulfiding requirements of hydrogenation catalysts. The decomposition temperature of SulfrZol 54 pre-sulfiding agent is lower than that of conventional pre-sulfiding agents, and the pre-sulfiding time for oxidized catalysts can be greatly shortened. In addition, the SulfrZol? 54 pre-sulfiding agent, which is low in odor, toxicity and decomposition temperature and high in flash point, offers good safety and operability. It can replace conventional pre-sulfiding agents like carbon disulfide, dimethyl disulfide, etc in pre-sulfiding of hydrogenation catalysts.%主要阐述SulfrZol(R) 54硫化剂在某炼油化工股份公司2 Mt/a加氢精制装置的首次应用.从使用效果来看,SulfrZol(R) 54硫化剂完全能满足加氢催化剂的硫化需要,并且从SulfrZol(R) 54硫化剂分解温度来看低于一般硫化剂,可以大大缩短加氢装置氧化态催化剂预硫化时间.另外,从SulfrZol(R) 54硫化剂与其它硫化剂物性分析来看,具有气味低、毒性小、分解温度低、闪点高等特点,有更好的安全性和操作性.因此,SulfrZol(R) 54硫化剂完全可以替代二硫化碳、二甲基二硫等传统硫化剂作为加氢催化剂硫化需要.
