METHOD OF THERMAL PROCESSES GASOLINES CATALYTIC REFINING Russian patent published in 2016 - IPC C10G47/32 

FIELD: technological processes.

SUBSTANCE: invention relates to method of thermal processes gasolines refining, involving their mixing with oil fractions - hydrogen donors at temperature of less than 100 °C with subsequent processing under catalytic cracking conditions at temperature of 420-480 °C in reactor-regenerator system, on catalyst for carrying out hydrogen transfer reactions. Hydrogen donors used are following oil fractions: straight-run wide gasoline fraction with start boiling point of 62 °C and with variable end boiling point to 180 °C, aromatic producing compound raffinate with start boiling point of 62 °C and with variable end boiling point to 180 °C, straight-run kerosene fraction with boiling temperature range of 140-240 °C, straight-run diesel fraction with boiling temperature range of 180-360 °C, at their ratio with thermal processes petrols of 1:(1-3). Thermal processes gasolines include thermal cracking processes, viscosity breaking, coking gasolines.

EFFECT: thermal processes gasolines catalytic refinement without using molecular hydrogen, wider raw material base for high-quality commercial gasolines producing, as well as higher yield of target gasoline fraction.
