Bio-based methanol gasoline composite auxiliary and bio-based high-proportion methanol gasoline

Abstract

The invention discloses a bio-based methanol gasoline composite auxiliary and a bio-based high-proportion methanol gasoline. The bio-based methanol gasoline composite auxiliary disclosed by the invention comprises the following eight additives with different effects and functions: 25-35% of a solubilizing cold starting agent, 12-20% of an anti-explosion gas resistance-reducing agent, 3-5% of an emulsifying and water-melting agent, 2-3% of an anti-corrosion inhibitor, 4-6% of an anti-swelling and degumming agent, 5-6% of a detergent dispersant, 16-25% of an oil product stabilizer and 10-20% of a power reinforcer, so that the respective advantages of all the functional additives are fully realized and the deficiencies in the functions are further overcome. The invention also relates to the bio-based high-proportion methanol gasoline which comprises 85-95% of bio-methanol or anhydrous industrial methanol, 4.2-14.5% of bio-based methanol gasoline component oil and 0.5-0.8% of the bio-based methanol gasoline composite auxiliary. The bio-based high-proportion methanol gasoline disclosed by the invention solves 24 technical difficult problems in eight major types in using process of methanol gasoline and improves the various performances of the high-proportion methanol gasoline.

Description

technical field [0001] The invention relates to the field of alcohol substitute fuels, in particular to a bio-based methanol-gasoline compound additive and a bio-based high-proportion methanol-gasoline. 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 valued for its abundant sources, and is consider...

Problems solved by technology

First of all, from the perspective of bio-based additives: most patents use plant long-chain unsaturated fatty acids as the main raw material in additives, and the patent numbers are CN100543117CA (soybean oil), CN101386795A (castor oil), CN100564496C (corn oil) CN101955808A (vegetable oleic acid) There are also reports of imported palm oil, but the patent report of using yeast fatty acid is the first case; in some cleaning and environmental protection patents, there are actually "unclean" reagents, such as CN101914394A containing MMT, CN101880556A containing MTBE, CN101302449A containing Ferrocene, CN101475850A contains xylene, CN100371428C contains toluene, CN102863993A contains trichlorotoluene, benzyl alcohol, xylene, etc.
