Abstract

The invention discloses a moderate-proportion methanol gasoline additive. The invention is characterized in that the additive is formed by mixing the following raw materials by volume percent: 5%-10% of ethanol, 10%-15% of isopropanol, 10%-15% of tertiary butanol, 5%-10% of benzene, 1%-5% of dimethylbenzene, 2%-5% of ethylbenzene, 5%-10% of petroleum ether, 1%-5% of hydrogen peroxide, 5%-10% of 3-ethyl toluene, 5%-10% of isobutanol, 1%-5% of ethyl ether, 1%-5% of isoamylol and 25%-30% of 120# solvent oil, wherein the volume percentage sum of the raw materials is 100%. In the moderate-proportion methanol gasoline additive, the physicochemical properties and combustion characteristic differences of different components are utilized, and substances of different systems are organically mixed and dissolved, thereby fully exerting the advantages of each component and overcoming the lacks of each component in property; and after the additive is added in the moderate-proportion methanol gasoline, the comprehensive performances of the moderate-proportion methanol gasoline, such as phase separation resistance, corrosion resistance, antiknock quality and antioxidation stability, can be effectively improved, wherein the effect of phase separation resistance is the most outstanding.

Description

technical field [0001] The invention belongs to the field of energy and chemical industry, and in particular relates to a medium-proportion methanol gasoline additive. Background technique [0002] With the depletion of oil resources, energy issues have increasingly become an important factor that directly affects the economic development of countries around the world. my country is currently the second largest oil importer in the world, and it needs to spend tens of billions of dollars to import oil from abroad every year. Moreover, with the improvement of people's living standards, the number of cars is also increasing rapidly, the consumption of gasoline and diesel is increasing, and the exhaust gas seriously endangers people's health. Therefore, the State Environmental Protection Administration vigorously promotes clean fuels, reduces emission pollution, and purifies urban air. . Alcohol and other alternative fuels are used to replace or partially replace traditional g...
