Methanol gasoline efficient composite additive and preparation method thereof

Abstract

The invention discloses a methanol gasoline efficient composite additive and a preparation method thereof. The methanol gasoline efficient composite additive is prepared from the following formula ingredients in parts by mass: 5 to 8 parts of diethoxymethane, 6 to 8 parts of [2.2]paracyclophan, 5 to 6 parts of tetraethylenepentamine, 2 to 4 parts of arachidic acid, 6 to 10 parts of tert-butyl methyl ether, 5 to 7 parts of n-heptane, 4 to 6 parts of propanediol butyl ether, 4 to 6 parts of 2,2,4-trimethylpentane, 6 to 8 parts of isooctyl phosphate, 2 to 4 parts of nanometer cobalt ferrite and 3 to 4 parts of coconut diethanolamide. The methanol gasoline efficient composite additive has the advantages that the effects of obviously improving the water resistance of methanol gasoline and obviously reducing the emission of NOX, HC and CO are achieved; meanwhile, the effects of improving the power and reducing oil consumption to a certain degree are also achieved through a special recipe.

Description

technical field [0001] The invention relates to the field of gasoline additives, in particular to a methanol-gasoline high-efficiency composite additive and a preparation method thereof. Background technique [0002] As the best substitute fuel for internal combustion engines other than petroleum fuels, methanol has the characteristics of high octane number, good antiknock performance, and high oxygen content, especially its emissions are relatively small for air pollution. The physical and chemical properties of methanol are closer to that of gasoline, and it can be blended with gasoline in a low proportion, and the engine can not be changed. However, due to the high latent heat of vaporization and low vapor pressure of methanol, it will cause the formation of mixed gas and difficulty in starting, so it is rarely used alone in gasoline engines. Methanol and gasoline mixed fuel with a low ratio (5% to 30%) have good combustion performance, high efficiency, cleanness and env...
