METHOD OF CATALYTIC CRACKING WITH MAXIMISED BASIC COMPONENTS OF DIESEL FUEL Russian patent published in 2015 - IPC C10G11/18 B01J8/24 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to catalytic cracking of hydrocarbons. Method involves cracking reaction stage in an upflow fluidised bed reactor, stage of cracked hydrocarbon and coked catalyst separation, stage of cracked hydrocarbon fractioning, and stage of the coked catalyst recovery, where source hydrocarbon materials are fed to the upflow reactor to catalyst deactivated partially by preliminary coking of at least a part of the catalyst in the same upflow reactor so that reaction temperature for effluents discharged from the reactor varies from 470 to 600°C; such preliminary coking can be implemented by injection of at least one hydrocarbon compound with boiling point not lower than 350°C to at least a part of recovered catalyst, limited by at least one zone determined by internal device in the upflow reactor bottom part; source hydrocarbon materials for processing are supplied downstream after the top end of the internal device in the reactor if viewed against the catalyst flow in the reactor. Also, the invention refers to device for cracking method implementation.

EFFECT: maximised basic components of diesel fuel.
