Methanol diesel fuel and preparation method thereof

Abstract

The invention discloses methanol diesel fuel, which is prepared from the following raw materials in part by volume: 50 to 80 parts of diesel, 15 to 40 parts of methanol, 6 to 18 parts of surfactant, 3 to 12 parts of cosolvent, 2 to 8 parts of corrosion inhibitor and 1 to 4 parts of cetane improver. The invention also discloses a preparation method for the methanol diesel fuel. The product has good intersolubility stability, can be stored for more than six months stably and cannot demix at normal temperature and normal pressure, solves the problems of corrosion and swelling of metal parts and rubber and plastic pieces, and prolongs the service life of machines; after the methanol diesel fuel is burned, waste gas and particles are greatly reduced; and the methanol diesel fuel can serve as clean energy to replace the conventional diesel, is directly used for civil use and industrial production, and has wide application prospect.

Description

technical field [0001] The invention relates to a methanol diesel, and also relates to a preparation method of the methanol diesel. Background technique [0002] With the rapid development of the national economy, the demand for energy is increasing day by day. Diesel, as the main fuel for high-power internal combustion engines, is often in short supply. Although international crude oil prices have dropped temporarily recently, in the long run, crude oil resources will always be exhausted. Moreover, the content of particulate matter, nitrogen oxides and hydrocarbons in diesel engine exhaust is very high, which pollutes the environment and seriously damages human health. Alcohol fuel, as an important renewable fuel, has been the biggest research focus in recent years. Alcohol fuel mainly refers to methanol and ethanol, which are easy to use, store and transport. Among them, the source of methanol is very rich, and it can be produced from solid raw material coal, liquid raw...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a methanol diesel with uniform shape, long stable period, good combustion performance and high efficiency and cleanliness, which not only increases the content of methanol, effectively solves the problem of stratification of methanol diesel, but also solves the problem of alcohol fuel under acidic conditions. The relatively corrosive problem has a good fuel-saving effect and effectively reduces the emission of harmful gases and particulate matter in the exhaust gas
