Problems solved by technology

Yang Yanzhao et al. (200710113211.6, Microemulsion Diesel Oil Additive and Its Application) The microemulsifier involved in the patent application is composed of cationic surfactant, medium carbon chain alcohol, organic acid, ammonia water and / or ethanolamine, ethanol. Microemulsion diesel oil has good stability, but after adding national standard diesel oil to microemulsion diesel oil, it is easy to break the emulsion and precipitate white flocs

Abstract

The invention relates to micro-emulsion clean fuel, which comprises the following components: 7 to 9 percent of fatty acid, 0.5 to 2 percent of organic amine, 1 to 2 percent of ammonia water, 80 to 85 percent of diesel, 6 to 10 percent of water and 0 to 1 percent of low alcohol. Except the flash point, other performances of the emulsion clean fuel are close to the international-standard diesel. However, a given quantity of water is doped in the fuel, so the adequate combustion of the fuel can be realized, the dependence on the petrochemical fuel can be reduced, the discharge of the harmful substances such as carbon oxide, nitrogen oxides, hydrogen carbonide, visible microparticles and the like can be reduced, and the environment-friendliness of the fuel can be improved. The micro-emulsion clean fuel can be mixed with the international diesel at a large proportion to use, can be used for the fuel devices such as vehicles, ships, industrial boilers and the like, solves the problems of the prior diesel that the supply is in shortage, the environmental pollution is serious and the like, and favors the popularization to use.

Description

technical field [0001] The invention relates to a microemulsion clean fuel, especially a microemulsion diesel oil. The microemulsion fuel of the present invention can replace petroleum diesel for vehicles, ships, industrial boilers and the like. Background technique [0002] In recent years, with the rapid development of my country's national economy and transportation industry, the demand for diesel has increased greatly. Corresponding to this, the current situation is that the world's environmental conditions are deteriorating day by day, and environmental problems such as global warming, the hole in the ozone layer, and acid rain are gradually being paid attention to by human beings. The incomplete combustion of diesel in the internal combustion engine results in high levels of particulate matter, nitrogen oxides and hydrocarbons in the exhaust, causing serious harm to the environment. Therefore, in order to solve the problems of oil shortage and environmental pollution...
