催化裂化原料加氢处理催化剂PHF-311的工业应用

中国石油石油化工研究院针对催化裂化原料预处理所研发的PHF-311加氢催化剂，于2019年9月在中国石油独山子石化分公司1.0 Mt/a蜡油加氢装置上成功应用。标定结果表明，在反应温度358.5℃、反应压力10.9 MPa、氢油体积比699、主剂体积空速0.94 h^-1的工艺条件下，加氢蜡油的硫质量分数为493μg/g,氮质量分数为474.8μg/g,残炭为0.15%,是优质的催化裂化原料；加氢柴油的硫质量分数为6.2μg/g,氮质量分数为30.8μg/g,可作为柴油调合组分。从装置运行情况可以看出，PHF-311催化剂表现出较高的加氢脱硫、脱氮及降残炭活性，能够满足企业对清洁燃料生产的要求。

COMMERCIAL APPLICATION OF PHF-311 CATALYST FOR FCC FEEDSTOCK HYDROTRERATING

The hydrotreating catalyst PHF-311 developed by PetroChina Research Institute of Petrochemical Technology for FCC feedstock pretreatment was successfully applied in the 1.0 Mt/a gas oil hydrotreating unit of PetroChina Dushanzi Petrochemical Company in September 2019. The calibration results show that under the process conditions of a reaction temperature of 358.5 ℃ ,a reaction pressure of 10.9 MPa, a volume ratio of hydrogen to oil of 699, a space velocity for main agent of 0.94 h^-1, the gas oil with sulfur mass fraction of 493 μg/g and nitrogen mass fraction of 474.8 μg/g, and carbon residue of 0.15% can be obtained, which is a high-quality catalytic cracking feedstock. The hydrotreated diesel with 6.2 μg/g of sulfur and 30.8 μg/g of nitrogen can be used as diesel blending component. From the operation of the unit, it could be seen that PHF-311 catalyst had higher activities of hydrodesulfurization, hydrodenitrification and residue carbon reduction, which could meet the requirements of enterprises for clean fuel production.
