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.
