A coupled reactor having a cracking section and a gasification section is used in the method: a heavy oil feedstock and a hydrogenation catalyst are fed into a cracking section, to generate light oil-gas and coke; the coke is carried by the coke powder into the gasification section, to generate syngas; a regenerated coke powder is returned to the cracking section; the syngas enters the cracking section and merges with light oil-gas, and enters a gas-solid separator, to separate out first-stage solid particles and second-stage particles in sequence, and a purified oil-gas product is collected; oil-gas fractionation of the purified oil-gas product is performed, and a light oil product and a syngas product are collected. Yield and quality of the light oil can be improved by the method.Type: GrantFiled: September 22, 2020Date of Patent: June 28, 2022Assignee: CHINA UNIVERSITY OF PETROLEUM-BEIJINGInventors: Yuming Zhang, Jinsen Gao, Xingying Lan, Chengxiu Wang, Xiaogang Shi

Patent number: 11230674Abstract: The present disclosure provides an integrated method and apparatus for catalytic cracking of heavy oil and production of syngas. A cracking-gasification coupled reactor having a cracking section and a gasification section is used as a reactor in the method. A heavy oil feedstock is fed into a cracking section to contact with a bed material in a fluidized state that contains a cracking catalyst, a catalytic cracking reaction is conducted under atmospheric pressure to obtain light oil-gas and coke. The coke is carried downward by the bed material into a gasification section to conduct a gasification reaction to generate syngas; the syngas goes upward into the cracking section to merge with the light oil-gas, and is guided out from the coupled reactor and enter a gas-solid separation system. Oil-gas fractionation is performed to a purified oil-gas product output from the gas-solid separation system to collect light oil and syngas products.Type: GrantFiled: September 22, 2020Date of Patent: January 25, 2022Assignee: CHINA UNIVERSITY OF PETROLEUM-BEIJINGInventors: Xingying Lan, Yuming Zhang, Jinsen Gao, Chengxiu Wang
