Problems solved by technology

The co-solvent prepared by the traditional process has a series of problems such as harmful gas emission, corrosion and swelling, water stratification, high-temperature air resistance, and low-temperature cold start difficulties due to immature chemical additive technology and blending technology.
There are five major problems in the existing technology: poor compatibility of oil and alcohol, turbidity in water separation, difficulty in cold start at low temperature, air resistance at high temperature and poor storage stability

Abstract

The invention discloses a bio-based methanol gasoline hydrotropy cold initiator and a preparation method thereof. The bio-based methanol gasoline hydrotropy cold initiator comprises the following components in percentage by weight: 6.0%-11.0% of hydrotropy cold initiating component, 6.0%-8.0% of low-temperature anti-freezing component and 81.0%-88.0% of boiling point lowering component, wherein the three functional components are uniformly stirred under the normal temperature to obtain the bio-based methanol gasoline hydrotropy cold initiator finished product. By selecting the petroleum yeast fatty acid which is cleanable, environment-friendly, reproducible and degradable as a cheap additive, the bio-based methanol gasoline hydrotropy cold initiator disclosed by the invention is energy-saving and emission-reducing. The oleyl alcohol phase stable phase is still as long as 180 days, so that a problem that a fuel oil system and an engine needs to be regulated and optimized when the methanol content exceeds 85% is broken through, and therefore, the technical problems including intermiscibility, low temperature cold initiation, low-temperature freezing resistance, oleyl alcohol layering, oleyl alcohol phase stability and the like when the methanol content is 85%-95% are effectively solved.

Description

technical field [0001] The invention relates to the field of alcohol substitute fuels, in particular to a solubilizing cold-start agent which mainly uses biomass energy and can be blended with bio-alcohols 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,...
