Problems solved by technology

However, when methanol burns, water turns into water vapor, and its heat cannot be used, and it will take away a lot of heat, which cannot be recovered, and instead increases fuel consumption. In addition, water will also accelerate the corrosion of alcohol-based fuels on the fuel system of the engine

Abstract

The invention provides compound fuel. The compound fuel is prepared from, by weight, 20-40% of methyl alcohol, 30-50% of naphtha, 5-20% of mixed aromatic hydrocarbons and 10-30% of coking toluene through chemical reactions. The invention further provides a preparation method of the compound fuel. The method includes the following steps of firstly, mixing and stirring mixed aromatic hydrocarbons and coking toluene to obtain cosolvent; secondly, mixing and stirring methyl alcohol and naphtha, adding the cosolvent obtained in the first step to the reaction system to obtain the finished product. The invention further provides application of the compound fuel as automotive petroleum. The fuel is prepared through the cosolvent according to the specific ratio, the mixing effect is good, and the water resistance and the cold start performance are good. The fuel can be independently used as automobile fuel to replace petroleum, and existing devices of automobiles do not need to be changed in use.

Description

technical field [0001] The invention relates to the field of fuels, in particular to a composite fuel and its preparation method and application. Background technique [0002] Fuel is widely used in industrial and agricultural production and people's life, and can release energy through chemical reactions. There are many kinds of fuel, the most common such as coal, coke, natural gas and biogas and so on. Gasoline and diesel are currently the most commonly used vehicle fuels. Gasoline and diesel oil obtained through petroleum refining have high energy density, low price, are not easy to deteriorate, and are easy to transport, so they are very suitable for ignition engines and compression ignition engines. [0003] With the rapid development of economy and society, global energy is becoming increasingly tense, and the earth's oil content is very limited. Finding alternative energy sources for oil has become an important national strategy for all countries. In order to solve...
