    摘要： The present invention provides a process for desulfurizing gasoline fraction by solvent extraction: introducing the gasoline fraction into an extraction tower at a lower-middle part thereof, introducing a solvent into the extraction tower at the top thereof, injecting saturated C5 hydrocarbon into a reflux device at the bottom of the extraction tower, wherein the gasoline fraction which is desulfurized flows out from the top of the extraction tower; the solvent that has extracted sulfide, aromatics and C5 hydrocarbon flows out from the bottom of the extraction tower, and is separated into a C5 hydrocarbon-containing light component, a sulfur-rich component, water and the solvent. The present invention also provides a process for deeply desulfurizing catalytic cracking gasoline, which flexibly combines the process described above and an existing desulfurization technology.

    摘要： 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.

    摘要： 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.
