Problems solved by technology

[0002] The blending process of high-clean methanol gasoline is simple, and its key technology is composite additives. Although the existing composite additives have various names, they still have various defects. For example: M30 methanol gasoline with patent No. The standard-increasing agents are only carbon alcohols, benzenes, antioxidants, petroleum solvents and ethers. These additives only play a role in mutual solubility and solubility enhancement in methanol-gasoline blending, solving the problem of methanol-gasoline ignition, easy stratification, The problem of thermal air resistance, but the problems of corrosion, swelling, antistatic, cold start, thermal air resistance, poor power performance, and high fuel consumption have not been resolved

Abstract

The invention discloses a high-performance clean methanol gasoline which has the advantages of low cost and high efficiency. The methanol gasoline comprises the following components in percentage by weight: 15 to 48 percent of methanol, 50 to 84 percent of crude gasoline and 1 to 2 percent of composite additive, wherein the composite additive comprises the following components in percentage by weight: 15 to 20 percent of multi-effect energizer, 30 to 41 percent of benzene compound, 0.5 to 24 percent of complexing agent, 8 to 24 percent of ether compound, 0.7 to 1.2 percent of detergent additive and 16 to 19 percent of multi-carbon alcohol. The product of the invention has the advantages of readily available raw materials, wide source and low cost, can meet the requirements of No.93 unleaded petrochemical gasoline and above when used as a vehicle fuel, can be used independently or mixed with gasoline and is not limited by the proportion and the engine does not need to be retrofitted inuse.

Description

technical field [0001] The invention belongs to the technical field of methanol gasoline, and in particular relates to high-clean methanol and composite additives with perfect performance. Background technique [0002] The blending process of high-clean methanol gasoline is simple, and its key technology is composite additives. Although the existing composite additives have various names, they still have various defects. For example: M30 methanol gasoline with patent No. The standard-increasing agents are only carbon alcohols, benzenes, antioxidants, petroleum solvents and ethers. These additives only play a role in mutual solubility and solubility enhancement in methanol-gasoline blending, solving the problem of methanol-gasoline ignition, easy stratification, The problem of thermal air resistance, but the problems of corrosion, swelling, antistatic, cold start, thermal air resistance, poor power, and high fuel consumption have not been resolved.
