BIOETHANOL AS A HIGH-OCTANE ADDITIVE TO MOTOR FUELS

In this study, bioethanol was produced from Bashkir grape biomass in a laboratory setting. Using a Chromatec-Crystal 5000M mass spectrometer, the composition of the resulting bioethanol was analyzed, revealing 88 % ethanol, 3.2 % water, 5 % butanol, and 3.5 % hexanol, as well as a small amount of impurities (0.3 % by weight). Various fuels were used in the experiment, including hydrotreated gasoline fraction, methyl tert-butyl ether, technical ethanol, and isobutyl alcohol as a stabilizer for the gasoline-ethanol mixture. Further studies included determining detonation resistance and analyzing the composition of vehicle exhaust gases using UIT-85m and VAZ-21129 units and Kolion-1VN and Ecolab Plus gas analyzers.
