Technical Field
The invention relates to the technical field of gasoline antiknock agents, in particular to a composite gasoline antiknock agent.
Background
Gasoline is a liquid fuel obtained by refining petroleum, is a main fuel of automobiles, and has the main component of C4-C12 hydrocarbons. The knocking phenomenon of the gasoline engine is that after a spark plug is ignited, before flame does not reach, a large amount of unstable peroxide is formed in a mixture of gasoline steam and air, spontaneous combustion is carried out to form a plurality of combustion centers, generated shock waves collide with each other, a piston head and a cylinder are violently collided, and a metal knocking sound is generated. The knock phenomenon is usually related to the quality of gasoline, octane number is an important index for measuring the anti-knock performance (anti-knock performance for short) of gasoline, and the difficulty and cost for improving the octane number of the gasoline by improving the oil refining process are higher, so the anti-knock performance of a gasoline product is usually improved by adding an anti-knock agent.
The anti-knock agent is mainly divided into a metal anti-knock agent and an organic anti-knock agent, and the metal anti-knock agent is gradually eliminated by the market because the metal anti-knock agent easily causes the problems of engine abrasion, spark plug blockage, environmental pollution and the like. The addition amount of the organic antiknock agent is large, such as 10% of the addition amount of MTBE and ethanol. Therefore, there is a need to develop an environmentally friendly gasoline antiknock agent with excellent antiknock performance and a small amount of additives to further meet the market demand.

Experimental example: detection of antiknock performance of gasoline
It is generally believed that the higher the octane number, the better the gasoline antiknock performance. Octane numbers are further divided into Motor Octane Number (MON) and Research Octane Number (RON). The detection standards are GB/T503-2016 (Motor method for gasoline octane number determination), GB/T5487-2015 (research method for gasoline octane number determination). The difference between RON and MON is called the sensitivity, and the average of both is called the antiknock index (AKI).
In the test, the antiknock agents of the examples and the comparative examples are added into gasoline according to the volume ratio of 0.5-2% for antiknock detection, and the RON, MON, sensitivity and AKI of the gasoline under different antiknock agent addition amounts are recorded respectively.
TABLE 1 antiknock performance (antiknock additive 0.5%)
TABLE 2 antiknock performance (antiknock additive 1%)
TABLE 3 antiknock performance (antiknock additive 2%)
The results in tables 1-3 show that: the antiknock of the embodiments 1-6 can obviously improve the antiknock performance of the gasoline, the RON of the gasoline is improved from 73 to 76-99, the MON is improved from 58 to 66-93, the sensitivity is 5-10, and the AKI 71-96. It can be found that the capillarisin is advantageous to increase RON, MON and AKI by comparing example 1 with comparative example 1, and the salvianolic acid addition is advantageous not only to increase the antiknock index but also to decrease the sensitivity by comparing example 2 with example 3.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
