Abstract

The invention relates to a cosolvent and in particular relates to a methanol straight-run gasoline cosolvent. The cosolvent consists of a solution A and a solution B, wherein the solution A comprises the following components in percentage by volume: 20-35% of methylbenzene, 35-55% of dimethylbenzene and 25-35% of naphthalene. The solution B comprises the following components in percentage by volume: 20-50% of dodecanol, 20-50% of n-caprylic alcohol, 0-30% of glycerin monostearate, 0-40% of oleic acid and 0-20% of biodiesel. The cosolvent has the beneficial effects of good hydrotropy effect and good water phase separation resistance.

Description

technical field [0001] The invention relates to a co-solvent, in particular to a methanol straight-run gasoline co-solvent. Background technique [0002] Since 1993, my country has become a net oil importer. In 2010, my country's net import of crude oil exceeded 200 million tons for the first time, and its dependence on foreign countries exceeded 55%. Methanol has the characteristics of low price, simple synthesis process, high calorific value of theoretical mixture, good transportability and low pollution. It is a clean fuel. Therefore, it is of great significance to develop methanol vehicle fuel with coal instead of oil. In recent years, my country's coal-based methanol production capacity and output have reached new heights. From 2000 to 2008, the annual growth rate of methanol production capacity was 25%, and the methanol production capacity in the mid-term of the "Twelfth Five-Year Plan" is expected to exceed 50 million t / a. Although methanol has more than 200 derivat...
