Abstract: In order to study the suitable technical route for the processing of products of slurry bed residual oil hydrocracking unit, SINOPEC Maoming Company entrusted SINOPEC Research Institute of Petroleum Processing Co., Ltd. to conduct experiments on various processing technology using the light oil fraction and vacuum gas oil(VGO) fraction produced by the unit as raw materials, and industrial applications have been carried out. The results indicate that after processing through hydroupgrading technology，heavy naphtha oil products is a high-quality heavy feedstock because of the high aromatic potential，the product diesel meets the national Ⅵ standard for automotive diesel. The VGO fraction can be used as a blending component for ship combustion after shallow desulfurization. After high-pressure hydrogenation treatment, the mass fraction of hydrogen of the VGO fraction can be increased to over 12.0%, and the mass fraction of nitrogen can be reduced to less than 500 μg/g. It can be used as a high-quality catalytic cracking feedstock. The VGO fraction can be converted into high-quality catalytic cracking feedstock through high-pressure mild hydrocracking process. After catalytic cracking technology conversion, the ethylene yield is 11.74%, the propylene yield is 20.65%, and the sum of ethylene, propylene, and butene yields is 42.62%. The industrial practice has verified the results of the pilot-scale test.
