Abstract: An integrated method and an integrated device for heavy oil contact lightening and coke gasification are provided. The integrated method uses a coupled reactor including a cracking section and a gasification section, and the integrated method includes: feeding a heavy oil material into the cracking section to implement a cracking reaction, to obtain a light oil gas and a carbon-deposited contact agent; passing the carbon-deposited contact agent into the gasification section, so as to implement a gasification reaction, to obtain a regenerated contact agent and a syngas; and discharging the light oil gas and the ascended and incorporated syngas from the cracking section, to perform a gas-solid separation, so that the carbon-deposited contact agent carried is separated and returned to the cracking section, and a purified oil gas is obtained at the same time.

Abstract: 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.

Abstract: The present disclosure provides a method and an apparatus for integrating pressurized hydrocracking of heavy oil and coke gasification. 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.
