多功能S Zorb吸附剂FCAS-MF在汽油吸附脱硫装置的工业应用

COMMERCIAL APPLICATION OF MULTIFUNCTION SORBENT FCAS-MF AT S Zorb UNIT

为满足汽油S Zorb超深度脱硫过程中降低辛烷值损失的要求,中国石化石油化工科学研究院研发了多功能S Zorb吸附剂FCAS-MF,并在中国石化长岭分公司1.2 Mt a汽油S Zorb工业装置上应用。结果表明:FCAS-MF具有较好的脱硫活性及稳定性,可以满足工业装置生产需要;与原用吸附剂FCAS-R09对比,FCAS-MF具有更好的降烯烃性能及辛烷值保留能力,在S Zorb工艺条件下,产品汽油硫质量分数小于10μg g时,烯烃转化率增加2~3百分点,研究法辛烷值损失减少0.3~0.6。

In order to meet the requirements of optimizing octane loss in ultra-deep desulfurization process,SINOPEC Research Institute of Petroleum Processing has successfully developed the multifunctional S Zorb sorbent FCAS-MF which is applied in a 1.2 Mt a S Zorb unit of SINOPEC Changling Refining&Chemical Company.The results show that the multifunctional sorbent FCAS-MF has better activity and stability than the sorbent FCAS-R09.Compared with the original sorbent FCAS-R09,FCAS-MF has better olefin reduction performance and octane number retention ability.Under the conditions of S Zorb process,when the sulfur content of product gasoline was less than 10μg g,the RON loss can reduce by 0.3-0.6,and the olefins conversion can increase by 2-3 percentage points.
