Abstract

The invention discloses a fuel alcohol and allocating method and application, which comprises the following parts: 55%-83% alcohol with density at 94%-96%, 5%-20% carbinol, 5%-10% isopropanol, 5%-10% isobutanol and 2-5% isoamyl alcohol, wherein the fuel alcohol is blended with automobile gasoline for car.

Description

technical field [0001] The invention relates to a fuel used in an internal combustion engine (mainly a gasoline engine) and a production method thereof, in particular to clean fuel ethanol mixed with water and a production method thereof. Background technique [0002] The current fuel ethanol uses absolute ethanol as the base material. In order to distinguish between fuel ethanol and absolute ethanol, and to prevent fuel ethanol from being used for other purposes, the currently used fuel ethanol is prepared by adding an appropriate amount of gasoline or denaturant to the absolute ethanol. . Current fuel ethanol is colored. However, the production cost of absolute ethanol is high, the process is complicated, the equipment investment is large, the technical requirements are high, the energy consumption is large, and the resource consumption is large. Extensive use of absolute ethanol consumes a lot of resources. Contents of the invention [0003] The object of the present...
