Problems solved by technology

The R&D and production of methanol gasoline, especially high-content methanol gasoline, face the following technical problems. First, due to the high octane number and low calorific value of methanol, when the amount of methanol added exceeds a certain value, the power performance will deteriorate; 2. Because the molecular structure of methanol and gasoline is different, it is the relationship between alcohol and hydrocarbon, and the mutual solubility is poor; 3. As a solvent, methanol has swelling and corrosion effects on rubber and copper parts of automobiles

Abstract

A high-performance high-content methanol gasoline contains methanol (45-55 Wt %), gasoline (40-50), benzene (0.5-3), mutually-dissolving additive (the mixture of dimethoxymethane and butanol) (2-4), power promoter (0.1-0.3) prepared from aviation kerosene and anhydrous hydrazine, and the dissolving and corrosion resistant (0.2-0.5) prepared from dialkyl-2.6 usbstituted-zinc phosphate and ammonium sulfonate.

Description

technical field [0001] The invention relates to methanol gasoline, in particular to a high-performance and high-content methanol gasoline. Background technique [0002] At present, low-content methanol gasoline (such as M5, M15) has been used commercially. High-content methanol gasoline with high methanol content and various physical and chemical properties basically the same as the existing motor gasoline is the direction of research and development at present. The R&D and production of methanol gasoline, especially high-content methanol gasoline, face the following technical problems. First, due to the high octane number and low calorific value of methanol, when the amount of methanol added exceeds a certain value, the power performance will deteriorate; 2. Due to the different molecular structure of methanol and gasoline, which is the relationship between alcohol and hydrocarbon, the mutual solubility is poor; 3. As a solvent, methanol has swelling and corrosion effects ...
