METHOD OF PRODUCING HIGH-OCTANE GASOLINE AND AROMATIC HYDROCARBONS Russian patent published in 1997 - IPC

FIELD: petroleum processing and petrochemistry. SUBSTANCE: production of benzene, toluene, and gasoline from reforming product is performed by separating the latter into three fractions with boiling ranges: up to 62 C, 62-105 C, and from 105 C to dry point. The second fraction is mixed with fraction of liquid pyrolysis products with boiling range 62-105 C at weight ratio (0.4-0.9):(0.6-0.1) and mixture obtained is submitted to hydrofining, selective hydrocracking, afterpurification, and extraction, after which raffinate is mixed with the above- mentioned first and third fractions at weight ratio (0.20-0.46): (0.1- 0.28):(0.42-0.52). EFFECT: produced high-octane non-ethylized gasoline with low benzene content. 7 cl, 5 tbl
