METHOD OF PREPARING HIGH-OCTANE GASOLINE Russian patent published in 1995 - IPC

Abstract SU 1817465 A1

FIELD: petroleum processing. SUBSTANCE: gasoline fraction to be refined is subjected for catalytic reforming. Reforming products were separated for the following fractions: low-boiling 62 C, medium-boiling 62-100 C and residual one. Medium-boiling fraction is subjected for hydrotreatment in the presence of catalyst containing, wt.-% high-siliceous zeolite 37-38; zeolyte Y 5-9; molybdenum oxide 8-9; palladium oxide 0.25-1.6, and aluminium oxide. Process is carried out at 280-400 C, at 1-4 MPa, volume rate of raw feeding 1-8 h^-1, ratio of hydrogen-containing gas 500-1500 nm³/m³ raw. Prepared products were mixed with low-boiling and residual fractions. Under these conditions the yield of gasoline is increased by 6-8 wt.-% and octane number by 0.5-2.5 points (research method). EFFECT: increased gasoline yield and its octane number. 2 cl, 1 tbl
