Method for preparing methanol gasoline additive by utilizing microbial fermentation illegal cooking oil product as main body and application of methanol gasoline additive

Abstract

The invention relates to alcohol alternative fuel. Concretely, yeast lipid is obtained by virtue of culture medium taking microbial fermentation illegal cooking oil, starch factory waste water and waste molasses as substrates; and a methanol gasoline additive is prepared by taking the yeast lipid as a main ingredient, wherein the additive contains a mutual dissolution-promoting and starting-assisting component, an anti-cylinder explosion anti-gas-blockage component, an anti-corrosion disperse colloid component, an accumulated carbon cleaning and oil product stabilizing component and a power-improving and combustion-promoting component in percentage by volume unit, and the functional components are uniformly stirred at normal temperature, so that the methanol gasoline additive is obtained;and methanol gasoline with low, medium and high methanol contents can be prepared from 10-80% of absolute methanol, 20-90% of gasoline and 0.1-0.5% of the additive. The methanol gasoline additive canbe used for solving the problem of discharge pollution of the illegal cooking oil, starch factory waste water and waste molasses and also can be used for solving the problems of shortage of domestic refined oil products, excess production capacity of methanol and ineffective utilization, and technical support is provided for popularization and application of methanol gasoline.

Description

technical field [0001] The invention relates to the field of alcohol substitute fuels, in particular to a method for preparing a methanol gasoline additive by using waste oil products fermented by microorganisms as a main body and its application. Background technique [0002] Since the birth of the first automobile in 1886, after more than 130 years, gasoline and diesel are still the main fuels for all kinds of motor vehicles, and this usage mode is increasingly constrained by serious environmental pollution and increasingly scarce resources. With the continuous advancement of science and technology and the continuous innovation of alternative energy sources, a large number of vehicle energy alternatives have emerged. However, if these alternatives are to be applied on a large scale, they are all subject to factors such as high cost, complex technology, and unsound supporting facilities. At the same time, the exhaust emissions of various motor vehicles contain a large amoun...
