Bio-based methanol gasoline product stabilizer and preparation method thereof

Abstract

The invention discloses a bio-based methanol gasoline product stabilizer and a preparation method thereof. The bio-based methanol gasoline product stabilizer consists of an inhibition aldehyde acid component, an acid-alkali balancing component, a viscosity improving component, a distillation range improving component and a stable liquid-phase component, wherein the five functional components are uniformly stirred under the normal temperature to form the bio-based methanol gasoline product stabilizer finished product. Compared with the prior art, the bio-based methanol gasoline product stabilizer is obvious in stabilizing effect and incapable of bringing secondary pollution to the environment. When the moisture content of the bio-based methanol gasoline product stabilizer exceeds 10%, the oleyl alcohol phase stable period is still as long as 180 days, so that a problem that a fuel oil system and an engine must be regulated and optimized when the methanol content exceeds 85% is broken through. The prepared methanol gasoline has excellent water resistance, low temperature resistance, acid-alkali balancing resistance, stability of long-term stored oleyl alcohol as well as no emulsion phenomenon and no phase separation phenomenon while being mixed with the goods gasoline at any proportion, so that the combustion is more complete, and the emission of formaldehyde, the formic acid and the tail gas pollutants is reduced.

Description

technical field [0001] The invention relates to the field of alternative fuels for alcohols, in particular to an oil stabilizer which mainly uses biomass energy and can be blended with bioalcohols in a high proportion and a preparation method thereof. Background technique [0002] For a long time, gasoline and diesel have been the main fuels for various types of motor vehicles. This usage pattern is increasingly restricted by serious environmental pollution and increasingly scarce resources. In order to improve this dilemma, a variety of energy alternatives have been adopted at home and abroad. However, if these alternatives are to be popularized on a large scale, there are serious defects. In recent years, as the international oil price continues to hover at a high level, the promotion, application and research process of alternative alcohol-ether fuels at home and abroad have been accelerated. Alcohol gasoline, as a clean, cheap and efficient gasoline substitute, has been...
