Ethanol gasoline composite additive and preparation method thereof

Abstract

The invention belongs to the field of petroleum product additives, and particularly relates to an ethanol gasoline composite additive and a preparation method thereof. The composite additive is prepared from co-solvent, combustion improver, corrosion inhibitor, vapor pressure inhibitor, detergent dispersant and surfactant serving as raw materials. The composite additive added into ethanol gasoline totally can replace gasoline, and is energy-saving, clean and environmentally-friendly. The ethanol gasoline prepared by using the additive can be mixed and used with the gasoline for vehicles in different ratios; the synthesized gasoline has no poor corrosion, has good dynamic property, oxidation resistance, explosion resistance and good oil-saving effect, prolongs the service life of an engine, obviously reduces harmful gas emission in automobile exhaust, is extremely favorable for protecting the environment and saving the energy, and has good economic benefit and social benefit; and because of the surfactant, the additive improves the storage and transportation stability of the ethanol gasoline, and does not produce phase separation or sediment after long-time storage.

Description

technical field [0001] The invention belongs to the field of petroleum product additives, in particular to an ethanol gasoline composite additive and a preparation method thereof. Background technique [0002] With the rapid development of our country's economy, the demand for energy is increasing day by day, especially with the rapid development of the automobile industry, our car ownership is increasing rapidly, causing the demand for motor vehicle fuel to grow too fast, increasing the oil consumption. Resource extraction and consumption. The limited oil reserves and production volume are difficult to meet the growing demand of the society, while the world's oil prices continue to soar and the international competition for oil resources is intensifying, making countries all over the world strengthen the research and development of oil alternative energy, get rid of the need for foreign oil Depending on imports, some fuel products that supplement or replace gasoline have b...

Problems solved by technology

For example, methanol gasoline is made by mixing and dissolving methanol and gasoline in a certain proportion. However, the methanol fuel technology being studied at home and abroad still has difficulties to be solved, such as methanol has a low calorific value and certain toxicity, and it is harmful to metal surfaces and rubber. The plastic pad has a certain degree of corrosion, low temperature phase separation, poor stability, etc.
