Abstract

The invention discloses high-energy composite alcohol radical gasoline. The high-energy composite alcohol radical gasoline is prepared from a modified additive, methanol and gasoline, wherein the modified additive is prepared from a cosolvent, a corrosion inhibitor, a detergent dispersant, a rubber plasticizer and a vapor pressure inhibitor. The invention also discloses a preparation method of the high-energy composite alcohol radical gasoline. With the adoption of the high-energy composite alcohol radical gasoline, the formula design is unique and reasonable, the intersolubility is good, the layering problem of methanol and gasoline is effectively solved, the water resistance is improved, the low-temperature ignition startability is good, the anti-corrosion swelling property is strong, no air-lock phenomenon occurs under extreme high temperature weather, the high-temperature lubricity is good, no destructiveness exists to engine oil, and the exhaust emission is superior to that of conventional petrochemical gasoline. The preparation method is simple in preparation process, is low in production cost, is easily implemented, is high in production efficiency, and is suitable for being widely popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of alcohol-based gasoline, and in particular relates to a high-energy composite alcohol-based gasoline and a preparation method thereof. Background technique [0002] With the development of the times, the use of new energy and clean fuels not only saves energy and protects the environment, but also does not endanger the environment and human health. In the current alcohol-based gasoline, the additives used are not high in power. The biggest technical problem is that it is difficult to start at low temperature, which is highly corrosive to the engine, and it is easy to produce abnormal phenomena after starting, which will lead to damage to the engine and damage to the engine. Swelling and damage of oil passages and rubber parts, high-temperature air resistance, and poor engine lubricity at high temperatures lead to technical difficulties such as doubling of cylinder wear and tear. Especially for large-scale ...
