FHUDS-6催化剂在柴油加氢装置中的应用

Commercial application of FHUDS-6 catalyst in diesel hydrofining unit

在中国石化西安石化分公司30万t/a柴油加氢精制装置上,对中国石化抚顺石油化工研究院研发的FHUDS-6超深度加氢脱硫催化剂的进行了工业应用。结果表明,在平均反应温度为357.6℃,反应器入口压力不小于7.2 MPa,主催化剂体积空速为2.37 h-1,氢气/原料油(体积比)为370的条件下,以硫含量为5 280μg/g的常二三线、减一线和催化柴油混合物为原料(三者质量分数依次为56%,13%,31%),可生产硫含量低于20μg/g的清洁柴油,其质量达到国Ⅳ标准要求。

FHUDS - 6 catalyst for diesel ultra - deep hydro- desulfurization developed by Fushun Research Institute of Pe- troleum and Petrochemical was applied to the 30 × 10^4 t/a hydrorefining unit of Xi＇an Petrochemical Company. The com- mercial application results showed that the clear diesel, which contained no more than 20μg/g of sulfur and the quality of which could meet national diesel standard IV, was produced with straight- run diesel, vacuum tower diesel and catalyticcracking diesel （ the mass fractions were 56% , 13% ,31% ,respectively, sulfur eontent 5 280μg/g） as material under the condition of average reaction temperature 357.6 ℃ ,inlet pressure of reactor no less than 7.2 MPa, main catalyst volumetric space velocity 2.37 h^-1 ,hydrogen to oil volume ratio 370.
