Abstract

The invention relates to high-octane unleaded synthetic gasoline-low carbon mixed alcohol gasoline, which belongs to the substitution fuel field. The invention adopts low- octane gasoline, high-octane low carbon mixed alcohol and auxiliary proper additive agent, therefore not only the invention can improve the octane value of gasoline, decrease the emission of CO and HC in the automobile exhaust, obviously reduce the generation of intake valve deposits, but also the allocated gasoline is not required to be added with any additive agent being helpful for dissolution, and the invention has good mutual solubility. The synthetic gasoline does not have bad corrosivity and corrosion, has the advantages of good oxidation resistance, good explosion resistance, good security, good stability and good detergency property, can directly replace the gasoline and is used for various vehicles, is very favorable for the environment protection and the energy conservation, and has good economic and social benefits. The manufacturing method is simple and feasible, and is easy for promotion.

Description

technical field [0001] The invention relates to a liquid fuel for a gasoline engine-low-carbon mixed alcohol gasoline, which belongs to the field of alternative fuels. More specifically, it is a kind of low-carbon mixed alcohol such as methanol, ethanol, propanol, butanol and pentanol and low-octane gasoline components as the main raw materials, and then supplemented with additives to improve performance An alcohol clean fuel. Background technique [0002] In the 21st century, all countries in the world will protect the environment, maintain the ecological environment, prevent and control pollution, and fully and effectively develop and utilize natural resources as an important strategy for their own economic development. At the same time, for the sake of energy security, countries get rid of their dependence on foreign crude oil imports and meet increasingly stringent environmental protection regulations for pollution control. The research on alternative fuels, especially ...
