METHOD FOR PRODUCTION OF MOTOR FUEL COMPONENTS Russian patent published in 1999 - IPC

Abstract RU 2139842 C1

FIELD: motor fuels. SUBSTANCE: isobutane preliminarily mixed with 91-97% sulfuric acid is alkylated for 20 min by thermal cracking gasoline fraction at 5-10 C, pressure 1.50-1.75 atm, isobutane/gasoline fraction volume ratio (1-2):1, isobutane/olefins ratio (1.5-2):1, and sulfuric acid/olefins ratio 1:1. EFFECT: increased yield of product by 28% (based on the weight of olefins), reduced process pressure, and reduced isobutane/olefins ratio. 2 tbl
