摘要: 采用SSY分子筛和Beta分子筛复配作为催化剂酸性组分,利用等体积浸渍法制备Ni-Mo-P/SSY-Beta-Al2O3催化裂化柴油加氢裂化催化剂,以中国石化青岛炼化分公司的催化裂化柴油为原料,在100 mL固定床加氢中试装置上进行催化剂的反应活性评价,考察了反应温度、压力和空速对Ni-Mo-P/SSY-Beta-Al2O3催化剂加氢裂化活性的影响。结果表明:在压力为8 MPa、氢油体积比为700:1、精制段温度为360 ℃、精制段体积空速为1.25 h-1、裂化段温度为400 ℃、裂化段体积空速为1.5 h-1的条件下,柴油馏分收率为58.67%,十六烷值提高了10个单位;汽油馏分收率为34.74%,辛烷值(RON)为91.37。

Abstract: Ni-Mo-P/SSY-Beta-Al2O3 hydrocracking catalyst was prepared by impregnation method using SSY and Beta zeolite as acid components and evaluated in a 100 mL fixed bed reactor using LCO from SINOPEC Qingdao Refining & Chemical Co. At the conditions of 8 MPa, H2/oil radio of 700:1, and Sv of 1.25 h-1 and 360 ℃ in hydrorefining zone, while space velocity of 1.5 h-1 and 400 ℃ in cracking zone, the diesel yield is 58.67 %, cetane number increases by 10 units, and the gasoline yield is about 34.74 % with RON of 91.37.
