Gasoline anti-knock agent mixture for vehicle

Abstract

The present invention relates to a vehicle gasoline antiknock additive mixture, which belongs to the gasoline antiknock additive technology field. The present invention uses cyclopentadiene manganese tricarbonyl (CMT) antiknock additive with more excellent antiknock performance to replace the prior methyl cyclopentadienyl manganese tricarbonyl (MMT) antiknock additive, to achieve the purposes of promoting the oil product octane number of gasoline components, in particular, promoting the oil product octane number of low grade gasoline components. The vehicle gasoline antiknock additive mixture of the present invention comprises antiknock additive, solvent, fluxing agent and antioxidating agent, wherein, the antiknock additive is methyl cyclopentadienyl manganese tricarbonyl. The technical effect of the present invention is outstanding, the octane number of the gasoline can be obviously promoted, in particular, the octane number of the low grade gasoline is promoted, and the octane number of a component gasoline is about 60 units, a high octane number gasoline is a high grade clean fuel after being concocted through adding the mixture of the present invention, and attains the national standards (GB17930-1999) of the vehicle gasoline, thereby pioneering the new way that the vehicle unleaded gasoline clean fuel is produced through the low grade oil products.

Description

technical field [0001] The invention relates to a gasoline antiknock agent mixture for vehicles, which belongs to the field of gasoline antiknock agents. Background technique [0002] 1. About the "knock" and octane number of gasoline engines [0003] An important indicator of the grade of gasoline for vehicles is the octane number of gasoline. When the octane number of gasoline is low, the combustion of the oil and gas mixture in the engine will be asynchronous, that is, abnormal combustion will occur two or more times during the combustion process of the engine. Knock sound, that is, the phenomenon of "knock combustion" of gasoline engine, referred to as knock, commonly known as "knock cylinder" or "valve sound" in the industry. Obviously, knocking is an abnormal combustion phenomenon of bad oil, which not only reduces the performance of the engine, but also causes damage and early failure of the engine parts. [0004] Studies have found that by adding certain organic s...

[0021] ① MMT pollutes groundwater

[0023] ②MMT is easily oxidized

[0026] When a specified amount of methylcyclopentadiene manganese tricarbonyl (MMT) is added to low-grade component oils, the effect on increasing the octane number is not significant
