METHOD OF PRODUCING HIGH-OCTANE ENVIRONMENTALLY PURE MOTOR FUEL Russian patent published in 1998 - IPC

Abstract RU 2106389 C1

FIELD: gasoline production. SUBSTANCE: reforming products are separated into three fractions: light fraction with boiling limits from boiling start to 62-65 C, middle fraction with boiling limits from 62-65 to 90-110 C, and heavy one boiling away above 110 C. Middle fraction is subjected to selective hydrocracking in presence of catalyst: 3.5-12.5% molybdenum oxide, 10-70% ZSM-5, ZSM-8, or ZSM-11 zeolite in H or Hli form with silicate modulus 4-20, 0.5-8.5% boron oxide, and aluminum oxide to balance. Hydrocracking products (20-30 wt %) are hydrogenated and mixed with light (20-30%) and heavy (45-55%) fractions. Hydrocracking is carried out at 280-400 C and pressure 1.5- 5.0 MPa. EFFECT: improved quality of fuel. 3 cl, 2 tbl
