Problems solved by technology

However, there are obvious deficiencies in the methanol-diesel blended fuel, which requires modification of the diesel engine, poor stability, and easy stratification. Especially when a large proportion of methanol is added, there are problems in the stability, flash point, and combustion performance of methanol-diesel, which still need to be further solved.

Abstract

The invention provides methanol diesel. The methanol diesel is prepared from all the components in percentage by weight: 60-85% of diesel, 5-30% of methanol, 1-5% of water, 1-10% of a modifier and 0.01-0.03% of KCl, wherein the modifier is prepared from the following raw materials in parts by weight: 5-10 parts of methyl tertiary butyl ether, 1-20 parts of isobutanol, 5-15 parts of isoamyl nitrate, 5-10 parts of diethylene glycol dialkyl ether, 1-5 parts of ferrocene and 1-5 parts of oleic acid. The methanol diesel provided by the invention has the advantages of good storage stability, high water resistance, high flash point, high cetane number and good low-temperature starting performance.

Description

technical field [0001] The invention belongs to the technical field of fuel, and in particular relates to methanol diesel. Background technique [0002] With the rapid development of the global economy, the demand for oil in countries around the world is increasing day by day, but oil is a non-renewable energy source, and the world's oil reserves are decreasing year by year. The shortage of oil has become a long-term pressure restricting the development of the world economy. At present, the main purpose of petroleum is to produce gasoline and diesel for use in internal combustion engines. However, due to the low combustion efficiency of internal combustion engines, a large amount of fine dust containing carbon-containing substances in the exhaust gas is suspended in the air, resulting in serious environmental pollution. Sulfur dioxide produced after combustion , polycyclic benzene carcinogens have caused great harm to human health. [0003] As an alternative energy source, ...
