GASOLINE PRODUCTION PROCESS Russian patent published in 1998 - IPC

FIELD: gasoline production. SUBSTANCE: invention is destined for application on catalytic reforming installations for straight-run gasoline fractions to yield high-octane gasolines. Five to seventy wt % of catalytic reforming gasoline is fractioned to isolate fraction boiling away above 110 C, which is further combined with catalytic reforming gasoline and alkylate at the proportion: 10-50, 10-70, and to 100 wt %, respectively. Final product may be supplemented with as high as 25 wt % of catalytic cracking gasoline and additionally with 1-15 wt % of ethers of C₁-C₅-alcohols or their mixture with C₁-C₄.-alcohols. EFFECT: extended choice of gasolines with improved antiknock properties. 3 cl, 2 tbl
