Abstract

The invention discloses a gasoline additive and belongs to the field of chemical industry. The invention aims to provide a high-efficiency gasoline desulfuration alcohol activating agent by aiming at the disadvantage of a gasoline alkali-free fixed bed desulfuration alcohol technology. The gasoline additive comprises the following raw materials in parts by weight: a pungent increasing agent, a catalyst, antioxygen, an antiknock agent, a cleaning agent and a solvent. According to the invention, the gasoline additive is added in an oil product in a certain ratio so that the octane numbers of low-grade naphtha and catalytic gasoline are improved to 93# and 97# from 80# and 90#; the gasoline additive is prepared at normal temperature and normal pressure and has the advantages of abundant raw material, simple technology, low cost and good anti-explosion performance; a gasoline detergent, the antioxygen and the like are added in the gasoline additive so that gasoline burning performance is improved, and carbon deposition and residual colloid generated on a gasoline engine after burning are removed; the octane number of the gasoline can be obviously improved, the octane number can be improved by 3-15 units, the anti-explosion performance of the gasoline is improved, the combustion performance of the gasoline in the gasoline engine is improved, the thermal efficiency is improved, oil consumption is lowered, power is improved, the discharge amount of harmful substances is lowered, and the service life of the gasoline engine is prolonged.

Description

technical field [0001] The invention belongs to the field of chemical industry. Background technique [0002] Combustion and knocking of gasoline: When the gasoline engine is working, gasoline and air form a uniform mixed gas in the combustion chamber. Affected by high temperature, RH in gasoline produces a large amount of ROOH and accumulates it. The flame propagation speed is particularly high during ignition, which causes the temperature and pressure in the cylinder to rise suddenly, the instantaneous temperature can reach 3000-4000 °C, the pressure can rise to more than 10 MPa, and the pressure propagation frequency can reach 5000 times / s, so that part of the fuel When the cylinder is exhausted before the combustion is complete, this is the phenomenon of knocking. The knocking phenomenon not only reduces the economy, power and thermal efficiency of the engine, but also damages the engine parts and shortens the engine working life. [0003] The significance of gasoline ...
