Problems solved by technology
At present, most of the methanol gasoline additives used in China are added alone, which can only make methanol and gasoline mix, and fail to make methanol and gasoline really blend, which will cause poor power and difficult to start in winter. When the proportion of methanol is relatively high, the methanol-gasoline prepared cannot reach the normal use effect at all. Therefore, we propose a low-carbon methanol-gasoline compound additive and its preparation method

Abstract
The invention discloses a low-carbon methanol gasoline composite additive in the technical field of methanol gasoline composite additives. The low-carbon methanol gasoline composite additive is prepared from the following raw materials in parts by weight: 5-10 parts of lubricating oil, 0.5-0.8 part of normal hexane, 0.2-0.5 part of cesium powder, 3-5 parts of aluminum oxide, 1-5 parts of a cosolvent, 2-3 parts of a calorific value improver, 0.5-2 parts of a corrosion inhibitor, 0.5-1 part of an antioxidant, 30-40 parts of isopropanol and 15-20 parts of isobutanol. According to the invention, methanol and gasoline can be organically dissolved to form a true solution, layering and emulsification are avoided, and infinite mutual dissolution with national standard gasoline, ethanol gasoline and the like is achieved. In addition, the low-carbon methanol gasoline composite additive has a certain calorific value improving effect, specifically, the calorific value is improved through methanol modification, and meanwhile, improvement of the combustion rate and the heat efficiency is promoted according to the characteristic that the latent heat of vaporization of methanol is high, the fuel has the same combustion effect as national standard gasoline in the combustion process, and the power is improved.
Description
technical field [0001] The invention relates to the technical field of methanol-gasoline composite additives, in particular to a low-carbon methanol-gasoline composite additive and a preparation method thereof. Background technique [0002] Due to the rapid development of the current economy, the demand for energy is increasing day by day, especially the demand for motor vehicle fuel is growing faster, and the limited oil reserves and extractions are difficult to meet the growing needs of society. In order to use existing resources to supplement and replace petroleum, people have gradually developed some fuel products that supplement and substitute petroleum. For example: Methanol gasoline is prepared by mixing and dissolving methanol and gasoline in a certain proportion, under the action of the main solvent and synthetic additives, and a certain amount of methanol is used to replace gasoline in methanol gasoline; [0003] Methanol gasoline refers to a certain volume fracti...
