Abstract

The invention discloses a compression ignition type modified methanol fuel and a preparation process thereof. The compression ignition type modified methanol fuel comprises the following raw materials in parts by weight: 40-65 parts of methanol, 30-55 parts of a modifier and 2-10 parts of a performance regulator. The modifier is prepared from the following raw materials in parts by weight: 5 to 20 parts of isopropanol, 5 to 15 parts of tertiary butanol, 5 to 15 parts of n-caprylic alcohol, 2 to 10 parts of 2-butyl methacrylate and 2 to 10 parts of petroleum ether. The performance regulator is prepared from the following raw materials in parts by weight: 2 to 10 parts of isopropyl alcohol, 0.1 to 1.0 part of dimethyl formamide, 0.01 to 1.0 part of benzotriazole and 0.01 to 1.0 part of isopropyl methyl phenol. The modifier and the performance modifier are used for modifying methanol, so the modified methanol can be used with national-standard diesel oil under the condition of a certain ratio, vehicles do not need to be modified during use of the modified methanol, and the modified methanol can be directly used; and the modified methanol and the diesel oil are very stable after being mixed, layering cannot occur during long-time storage, and no damage is caused to an oil pump, an oil way and an engine cylinder body.

Description

technical field [0001] The invention relates to the technical field of energy fuels, in particular to a compression ignition type modified methanol fuel and a preparation process thereof. Background technique [0002] my country is the world's largest energy consumer. It has the characteristics of lack of fossil energy, oil, gas, rich coal, and abundant renewable scenery resources. In 2018, it imported 460 million tons of oil, and its dependence on foreign countries was 70.6%, about half of which came from Iran and other Middle East countries. Imports from risky areas face the risk of oil supply being cut off at any time, which has become the weakness of economic and social development. The implementation of an alternative oil strategy is an inevitable choice, and it is also a major issue related to national security. [0003] At present, methanol is an inevitable choice to replace petroleum. There are many paths to replace petroleum: Methanol, ethanol, electricity and hydro...
