Alcohol hydrocarbons composite for cars and preparation method thereof

Abstract

The present invention relates to the liquid fuel technical field, in particular to an alcohol hydrocarbon complex liquid fuel for a car and a preparation method thereof. The compositions in percentage by weight of the liquid fuel are: 20 to 40 percent of alcohol, 40 to 60 percent of light hydrocarbon, 8 to 12 percent of solvent naphtha, 10 to 15 percent of methyl tert-butyl ether, and 0.01 to 0.05 percent of functional additive, wherein the alcohol is methanol or ethanol, the light hydrocarbon is naphtha or light hydrocarbon between C6 and C12. The method comprises the following steps of: mixing the 20 to 40 percent of alcohol with the 0.01 to 0.05 percent of functional additive at a the temperature of between 0 and 20 DEG C; stirring for 10 minutes to obtain a mixed solution A; mixing the 40 to 60 percent of light hydrocarbon and the 8 to 12 percent of solvent naphtha, and then stirring for 10 minutes to obtain a mixed solution B; mixing the mixed solution A with the 10 to 15 percent of methyl tert-butyl ether, and then stirring for 10 minutes; mixing with the mixed solution B, and stirring for 10 minutes and sealing for 24 hours, and thus obtaining the product. Compared with the non-premium grade gasoline, the product is increased in oxygen content, sufficient in combustion, beneficial to environment protection, and can reduce the noxious gas of the automobile exhaust emission. Not only the cost is low and the material is easy to get, but also the required devices are less and the process is simple.

Description

technical field [0001] The invention relates to the technical field of liquid fuels, in particular to an alcohol-hydrocarbon composite liquid fuel for automobiles and a preparation method thereof. Background technique [0002] The current automobile fuel consumes a large amount of non-renewable natural resources, and the raw materials are limited, so the price is rising day by day, reaching an unbearable level. After burning, it will pollute the environment and endanger human health. And the present preparation method is very complicated, and the equipment used is various, and production cost is high. At the same time, there is also the problem of unsafe transportation. In order to protect non-renewable natural resources, reduce environmental pollution, reduce production costs, solve transportation safety problems, and benefit mankind, it is necessary to develop a new type of fuel for vehicles.
