METHOD OF ENGINE FUELS PRODUCTION Russian patent published in 2005 - IPC

Abstract RU 2252242 C1

FIELD: petroleum refining industry; production of engine fuels.

SUBSTANCE: the invention is pertaining to the field of petroleum refining industry, in particular, to production of engine fuels. Substance: the method provides for carrying out a catalytic cracking of petroleum fractions in presence of platinumzeolite-bearing rare-earth aluminum-silicate catalyst. The used catalyst consists of 5-20 mass % of "Y" zeolite with a molar ratio of silicon oxide to aluminum oxide within 4.5-9.5 and 80-95 mass % of the silica-alumina base in turn consisting of 40-95 mass % of amorphous aluminosilicate and 5-60 mass % of clay, and having a chemical composition, in mass %: aluminum oxide - 4.5-40.0, oxides of rare earths - 0.5-4.0, platinum - 0.0001-0.01, sodium oxide - 0.01-0.5, silicon oxide - the rest. The technical result: increased output of a gasoline fraction.

EFFECT: the invention ensures increased output of a gasoline fraction.
