COMBINED METHOD OF CATALYTIC CRACKING IN CATALYST FLUIDISED BED FOR PRODUCING HIGH-QUALITY HYDROCARBON MIXTURES AS FUEL Russian patent published in 2014 - IPC C10G11/18 C10G69/04 C10G65/02 B01J21/12 B01J23/40 B01J29/70 

FIELD: oil and gas industry.

SUBSTANCE: invention is related to a combined method of conversion of oil-derived hydrocarbon fractions into high-quality hydrocarbon mixtures as fuel, which includes catalytic cracking of hydrocarbon fraction in catalyst fluidised bed with catalyst containing ERS-10 zeolite, where the specified catalyst contains at least two components, where the specified components represent: (a) a component containing one or more catalytic cracking catalysts in fluidised, and (b) a component containing ERS-10 zeolite for obtaining Light Cycle Gas Oil (LCGO), hydrotreatment of light cycle gas oil, interaction of hydrotreated light cycle gas oil obtained at the previous stage of hydrotreatment in presence of hydrogen with catalytic system. The invention also touches the method of catalytic cracking and a stage of catalytic cracking in fluidised bed.

EFFECT: production of high-quality hydrocarbons, conversion increase.
