Problems solved by technology

However, only a small amount of MMT is discharged after the gasoline with MMT is burned, and most of it remains inside the exhaust system and covers the surface of engine spark plug catalysts and other components, which will cause spark plug ignition failure
At the same time, the content of MMT in domestic gasoline standards has been limited, from the original 18mg / L to the current 16mg / L, and in GB17930-2011, the manganese content in National IV gasoline is further reduced to 8mg / L, so that the content of The use of manganese MMT is restricted, and a new octane booster with qualified manganese content and good antiknock performance must be developed

Abstract

The invention provides a gasoline octane number enhancer composition capable of greatly enhancing antiknock property of gasoline fuel. The additive comprises a gasoline antiknock agent methyl cyclopentadiene tricarbonyl manganese (MMT), an alcohol octane number accelerator, an amine accelerator, an amide accelerator, an alkyl phenol octane number enhancer, a metal extraction additive and a cosolvent. The gasoline octane number enhancer provided by the invention can enhance the gasoline octane number by 2.0-10.0 units, has the characteristic of preventing increase of engine deposits, and can not damage the automobile engine.

Description

technical field [0001] The invention relates to the field of petroleum product additives, in particular to a gasoline octane number enhancer composition capable of greatly improving the antiknock performance of gasoline fuel. Background technique [0002] Gasoline engine knocking is largely related to the nature of the fuel. If gasoline is easily oxidized, the peroxide formed is not easy to decompose, and the spontaneous ignition point is low, so knocking is easy to occur. Therefore, gasoline antiknock is one of the most important indicators of gasoline quality, usually measured by octane number, gasoline with high octane number, good shock resistance and good quality. Existing methods for increasing the octane number of gasoline are: [0003] ① Through catalytic cracking, reforming, alkylation and other petroleum refining methods; [0004] ② Blend gasoline components with different octane numbers according to the optimal ratio; [0005] ③ Add octane number improver to ga...
