Abstract

The invention provides a vehicle fuel and a preparation method thereof. The vehicle fuel comprises the following components in parts by weight: 5-10 parts of diesel oil, 30-80 parts of polymethoxy dimethyl ether, 1-5 parts of an alcohol combustion improver, 1-5 parts of a corrosion inhibitor, 1-10 parts of an anti-detonator, 1-5 parts of a catalysis combustion improver, 1-10 parts of a stabilizer, 1-5 parts of an anti-oxidant, 0.1-5 parts of a dispersing agent and 5-10 parts of solvent oil. The preparation method comprises the following steps: sufficiently stirring and mixing the diesel oil, the polymethoxy dimethyl ether and the solvent oil at normal temperature to obtain a first mixture; under the stirring state, adding the alcohol combustion improver, the corrosion inhibitor and the catalysis combustion improver into the first mixture to obtain a second mixture; under a stirring and 35-60 DEG C constant-temperature condition, adding the stabilizer, the anti-detonator, the anti-oxidant and the dispersing agent into the second mixture, wherein the time interval of addition between adjacent substances is 1-2 hours; and preserving the heat and standing for 3-5 hours after stirring for 1-2 hours. The vehicle fuel provided by the invention is good in stability, and the utilization rate of the polymethoxy dimethyl ether is high.

Description

technical field [0001] The application relates to the field of energy, in particular to a vehicle fuel and a preparation method thereof. Background technique [0002] China is a big energy consumer, but China is also a country with relatively poor oil and gas resources. This contradiction brings great challenges and hidden dangers to China's energy security. On the one hand, adjusting the energy structure, on the other hand, looking for alternative energy sources has become an important way to alleviate energy pressure. [0003] The main raw material of polyoxymethylene dimethyl ether (DMMn, n is generally 2-8) is methanol, which has a wide range of raw materials and low price, and is very easy to obtain in my country; in addition, polyoxymethylene dimethyl ether is used as a diesel additive. It can effectively improve the combustion quality of diesel in the engine, increase thermal efficiency, and reduce pollutant emissions. It is considered to be a diesel additive with gre...
