Abstract

The invention relates to the technical field of methanol gasoline, in particular to an M85 methanol gasoline and a preparation method thereof. According to the preparation method, methanol, gasoline, sodium methoxide, pine oil, waste oil, glycerin, acetone and polyoxyethylene ether are mixed according to a proportion; the pine oil and the waste oil are separately treated through the combination of preparation process steps; the treated pine oil and waste oil are added for mixing; ultrasonic mixing treatment is performed during treatment processes, so that all raw materials are dispersed more uniformly, mutual concurrent effects among the methanol, gasoline, waste oil and other raw materials are further achieved, and then the quality of the methanol gasoline is improved. Particularly, the phenomenon that the methanol gasoline is easy to be subjected to stratification when the water content reaches 3% is avoided. Therefore, the water resistance of the methanol gasoline is improved, the guarantee period of the methanol gasoline is prolonged, and the storage difficulty of the methanol gasoline is lowered.

Description

technical field [0001] The invention relates to the technical field of methanol gasoline, in particular to M85 methanol gasoline and a preparation method thereof. Background technique [0002] With the increase of the global population and the continuous improvement of people's living standards, the demand for energy is becoming stronger and stronger. Especially with the rapid development of petrochemical industry in the mid-20th century, the pace of energy industry development has been accelerated. Petroleum consumption is increasing year by year, and the environmental pollution caused by the burning of petroleum products is becoming more and more serious. Using petroleum products as fuel, the carbon, nitrogen, sulfur oxides, and hydrocarbons contained in the tail gas of automobiles are harmful to the environment. caused great harm. At the same time, this has also made traditional oil and natural gas resources increasingly scarce. According to surveys, the world's proven ...
