High-cleaning composite gasoline and preparation method thereof

Abstract

The invention relates to high-cleaning composite gasoline and a preparation method thereof. The high-cleaning composite gasoline comprises the following components in part by weight: 10 to 25 parts of methanol, 15 to 20 parts of naphtha, 52 to 74 parts of solvent gasoline and 1 to 3 parts of additive, wherein the additive is prepared from 10 weight percent of tridecyl alcohol, 10 weight percent of hexadecyl sodium sulfonate, 20 weight percent of hexadecyl calcium sulfonate, 50 weight percent of naphthenic acid, 2.5 weight percent of tertiary butanol, 2.5 weight percent of isobutanol and 5 weight percent of isopropanol. The preparation method comprises the following steps of: 1) preparing the additive; 2) preparing denatured methanol; and 3) blending the denatured methanol, the naphtha and the solvent gasoline to prepare the high-cleaning composite gasoline. The high-cleaning composite gasoline of the invention has good cold boot, strong anti-corrosion performance, full combustion, powerful motive power and clean discharged tail gas and abundant sources and low cost of raw materials, and can solve the problem that natural fuel is in short supply.

Description

technical field [0001] The invention provides a gasoline substitute product, in particular to a high-clean composite gasoline and a preparation method thereof. Background technique [0002] With the development of the economy, the problem of insufficient oil reserve resources in our country has fully emerged. The development of clean and renewable energy has become the subject of the highest concern rate in our economic life. Existing composite unleaded gasoline is generally made up of methanol, solvent gasoline, xylene, and isopropanol. This kind of gasoline has the following disadvantages: (1) methanol has certain corrosiveness, and it will damage fuel tanks, oil circuits, and parts of automobiles. have a certain impact. (2) When the temperature is lower than 0°C, the compound gasoline will be stratified, which will affect the starting of the vehicle. (3) When the temperature exceeds 40 °C, the activity of methanol is enhanced, and it is easy to form a vapor flow, there...

Problems solved by technology

Existing composite unleaded gasoline is generally made up of methanol, solvent gasoline, xylene, and isopropanol. This kind of gasoline has the following disadvantages: (1) methanol has certain corrosiveness, and it will damage fuel tanks, oil circuits, and parts of automobiles. have a certain impact

(2) When the temperature is lower than 0°C, the compound gasoline will be stratified, which will affect the starting of the vehicle

(3) When the temperature exceeds 40°C, the activity of methanol is enhanced, and it is easy to form a vapor flow, thereby causing air resistance

(4) Solvent gasoline has high colloid, which will not only affect the stability of compound gasoline, but also affect the work of the engine
