Abstract

The invention relates to high-cleanness automotive methanol diesel oil and a preparation method thereof. The methanol diesel oil is formed by preparation of methanol, diesel oil, surfactants, emulsifying agents, corrosion inhibitors and cosolvents. The preparation method includes: 1), under normal pressure and temperature, adding polyoxymethylene dimethyl ether into a mixing tank, sequentially adding n-decanol, capryl alcohol and vegetable oleic acid into the mixing tank proportionally and evenly stirring to obtain the cosolvents; 2), adding the obtained cosolvents to a mixing tank, adding the emulsifying agents and the corrosion inhibitors proportionally and evenly stirring to obtain a solution A; 3), adding the diesel oil and the surfactants to a mixing tank proportionally and continuously stirring to obtain a solution B; 4), adding the solution A to the solution B, adding the methanol into the mixed solution, and circularly and evenly stirring by a fluid delivery pump until liquid becomes clear to obtain a methanol diesel oil product. The preparation method is simple, the prepared oil product is high in flash point and cetane number, stable in performance and full in combustion, emission of pollutants such as carbon monoxide, sulfur dioxide, nitrogen oxides and inhalable particles can be reduced effectively, production cost is low and economic benefit is high.

Description

technical field [0001] The invention relates to the technical field of methanol fuel, in particular to a high-clean vehicle methanol diesel and a preparation method thereof. Background technique [0002] With the rapid development of the national economy, my country's demand for energy is increasing day by day, and the consumption of liquid fuels that use petroleum as raw material continues to increase. Due to the lack of oil resources in our country, actively developing alternative energy sources is an important issue facing our country's energy security. In recent years, the domestic diesel shortage has intensified, and an alternative fuel is urgently needed to solve the shortage. Methanol is recognized as a promising and clean alternative fuel for internal combustion engines due to its advantages of wide sources, high oxygen content, good combustion performance, and low emission pollution. [0003] Although methanol has a series of advantages as an alternative fuel for ...
