High-stability methanol gasoline and preparation method thereof

Abstract

The invention belongs to the field of fuel chemical industry, and particularly relates to high-stability methanol gasoline and a preparation method thereof. The high-stability methanol gasoline at least comprises the following preparation raw materials in parts by weight: 40-80 parts of base oil, 20-50 parts of methanol, 1-10 parts of a cosolvent, 1-5 parts of a corrosion inhibitor, 0.5-1 part of an antiknock agent and 20-40 parts of an auxiliary agent. According to the present invention, a certain cosolvent is added to the methanol gasoline, and the intermiscibility and the stability between the methanol and the gasoline are improved through the cosolvent, such that the methanol gasoline can maintain the uniform state after the long-term placement so as to reduce the layering phenomenon of the methanol gasoline; according to the present invention, the corrosion of the methanol gasoline on the gasoline engine is reduced by adding the certain corrosion inhibitor, the anti-explosion performance of the methanol gasoline is improved by adding the certain anti-explosion agent so as to improve the stability of the methanol gasoline, and the cleanliness and the stability of the methanol gasoline are improved by adding the certain auxiliary agent so as to improve the use quality of the methanol gasoline.

Description

technical field [0001] The invention belongs to the field of fuel chemical industry, belongs to the technical field of classification number C10L, and particularly relates to a high-stability methanol gasoline and a preparation method thereof. Background technique [0002] Methanol gasoline is a new type of environmentally friendly fuel, a fuel substitute for automobiles, and an important part of new energy. Crude oil is the most important primary energy source in the world. The essence of the current energy shortage is the shortage of crude oil. Vehicle fuel is the most important application area of ​​crude oil, accounting for more than 70% of the total global crude oil consumption. Methanol gasoline is a "coal-to-oil" route, which can be used as a substitute for gasoline to partially replace crude oil. However, the methanol gasoline currently sold on the market has poor stability, serious corrosion of gasoline engines, and more carbon deposits, which seriously reduces th...
