Additive for improving water resistance of methanol gasoline

Abstract

The invention discloses an additive for improving the water resistance of methanol gasoline, which is prepared by mixing the following components in percentage by weight: 45-55% of C3-5 monohydric mixed alcohol, 20-30% of isobutenylamide isoheptyl ester and 25-30% of surfactant. The additive disclosed by the invention can improve the water-phase separating property of methanol gasoline, is superior to the traditional alcohol additive in water-resistant effect and can ensure that the water resistance of Chinese standard 93# gasoline is increased by 0.3% during methanol-blended combustion. The additive disclosed by the invention is low in production cost, remarkable in effect and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of methanol fuel for vehicles, and relates to an additive for methanol gasoline for vehicles, in particular to an additive for improving the water resistance of methanol gasoline. Background technique [0002] With the rapid development of the current economy, the demand for energy is increasing day by day. Gasoline is one of the most important non-renewable energy sources. As the world's natural oil reserves are decreasing year by year, countries around the world are actively using existing resources to find some clean energy products that can replace gasoline. Methanol gasoline has emerged as the most potential fuel substitute. and is becoming more and more popular. [0003] Methanol has a wide range of sources, which can not only optimize the structure of fuel sources and alleviate the dependence on petroleum fuels, but also bring opportunities and benefits to enterprises that produce methanol by-product...

Problems solved by technology

Most of these studies use traditional water-repelling additives, which require a large amount of additives and high costs, and the effect is not obvious in high-humidity areas (Zhao Rongxiang et al. Synthesis of heavy oil catalytic cracking surfactants. Journal of Liaoning Petrochemical University, 2009, 29(2) : 34-35, 38.)
