- W2367564674 abstract "A FCC feed pre-hydrotreating catalyst with high desulfuration and denitrogenation activity was developed to meet the requirements of FCC feed pretreating process. The catalyst was prepared by using fluorine modified Al2O3 as the carrier,and Ni and Mo metals as the active components. The catalyst possessed BET surface area of 169 m2·g- 1,pore volume of 0. 31 m L·g- 1,BJH average pore diameter of 6. 5 nm,most probable pore size of 3. 35 nm and 8. 00 nm,and pore diameter of( 4- 10) nm occupied71%. The catalyst featured large pore volume,high surface area and high dispersion of active components.Using blending gas oil with high sulfur and low nitrogen contents from Sinopec Qingdao Refining and Chemical Co.,Ltd. and coking gas oil with high sulfur and high nitrogen contents from Jiangsu Xinhai Petrochemical Co.,Ltd. as the raw materials,the active performance of hydroprocessing catalyst was evaluated in a 100 m L high pressure fixed-bed reactor. The results demonstrated that under the condition of reaction temperature 370 ℃,H2 pressure 10 MPa,space velocity 1. 0 h- 1and H2/ oil volume ratio 700∶ 1,desulfurization and denitrogenation rates for blending gas oil were 98. 0% and 96. 5%,and desulfurization and denitrogenation rates for coking gas oil were 93. 2% and 90. 0%,respectively. The catalyst with high hydrogenation activity had the advantages of increased feed adaptability and effective removal ratios of sulfur and nitrogen compounds." @default.
