Development of E30 Bioethanol Fuel Composition Based on Low-Octane Fractions of Exhaustive Hydrocarbon Feedstock Processing

The results of studies aimed at developing E30 bioethanol fuel composition using heavy low-octane hydrocracking gasoline as the basic component are reported. The dependencies of knock resistance, saturated vapor pressure, and fractional composition on bioethanol concentration in a mixture with heavy hydrocracking gasoline are shown. The maximally permissible concentrations of additional components (light hydrocracking gasoline, toluene, and reforming gasoline) in the fuel are indicated. The results of tests of experimental specimens in compliance with OAO VNII NP (OJSC All-Russian Scientific Research Institute of Oil Refining) technical specifications and calculation of economic feasibility of production and use of E30 bioethanol fuel are presented.
