由抚顺石油化工研究院研制开发的一种既可在低压、高空速、低氢油体积比条件下，用于高硫重整原料预加氢，为催化重整提供合理原料，还可用于煤油加氢精制的ＦＤＳ－４Ａ轻质馏分油加氢精制催化剂，日前在北京通过中国石化集团公司组织的技术鉴定。专家认为，新催化剂是４８１ Developed by Fushun Research Institute of Petrochemical Technology, it can be used for pre-hydrogenation of high-sulfur reforming feedstock under the condition of low pressure, high airspeed and low hydrogen oil volume ratio to provide reasonable raw materials for catalytic reforming. It can also be used for kerosene Hydrofinished FDS-4A light distillate hydrotreating catalyst, recently passed in Beijing, China Petrochemical Corporation organized technical appraisal. Experts believe that the new catalyst is 481
