Problems solved by technology

[0004] (1) The fuel saving and emission reduction effect of most gasoline additives (such as Chinese patent publication CN1597877A) is not obvious
[0005] (2) Some gasoline additives have the problem that the physical and chemical properties of gasoline do not meet the national standard, and have a negative impact on gasoline quality and equipment, such as changing the pH of fuel and corroding equipment
[0006] (3) Some gasoline additives cause serious environmental pollution
For example, most gasoline additives contain heavy metal elements (such as tetraethyl lead, ferrocene, etc.), leading to negative effects such as environmental pollution
More specifically, in order to improve the anti-knock index, the oil refining industry and fuel additive manufacturers use a variety of isooctanes to increase the octane number, but isooctane products often contain heavy metal elements, causing environmental pollution

preparation example Construction

[0046]The pea flour used in preparing the active liquid according to an exemplary embodiment of the present invention may have a particle size of 5 μm to 60 μm (for example, a particle size of 5 μm to 50 μm, a particle size of 5 μm to 35 μm) and a water content of not more than 2% (for example, 0.3% to 2% water content). If the particle size of pea flour is less than 5 μm, it may cause difficulty in solid-liquid separation; if the particle size of pea flour is larger than 60 μm, the interaction between pea flour and kerosene may be insufficient. However, the particle size of pea flour is not limited to the above particle size range. That is to say, the above-mentioned particle size range of pea flour can be expanded by improving the solid-liquid separation technology and prolonging the action time. If the moisture content of pea flour exceeds 2%, it may adversely affect the performance of gasoline additives. However, the moisture content of pea flour is not limited to the ab...

Abstract

The present invention discloses a gasoline additive, a preparation method and a use method thereof. The gasoline additive comprises 88-92% of a base oil, 6.7-11.4% of an active liquid, 0.2-0.5% of fatty acid methyl ester, 0.3-0.5% of polyisobutylene and 0.1-0.3% of triethylene glycol, wherein the base oil contains 50-64% by weight of gasoline, 25-30% by weight of naphtha, 5-9% by weight of triethanolamine, and 6-11% by weight of tetrahydrofuran, a mixture comprising 90-93% by weight of kerosene and 7-10% by weight of pea powder is subjected to lighting, and then the liquid in the mixture is separated as the active liquid. According to the present invention, the gasoline additive has effects of gasoline saving and emission reducing, and further has characteristics of adjustment of physical and chemical properties of the gasoline within the national standard range, improvement of the gasoline product quality, and reduction of environmental pollution.

Description

technical field [0001] The invention relates to a fuel additive and a preparation method thereof, in particular to a gasoline additive, a preparation method and a use method thereof. Background technique [0002] When the petroleum refining industry produces refined oil fuels, in order to increase the output, catalytic cracking technology is used. The finished gasoline produced by this technology has the problems of unstable oxidation stability and decreased octane ratio from production, storage and transportation to combustion. is the root problem of all the defects of gasoline. Specifically, the problems that lead to defects in this process mainly include: (1) acid-base reaction: organic acid and alkali nitrogen compound generate sediment; (2) olefin oxidation and enol co-oxidation: olefin and oxygen form colloid, Alkenes, oxygen, and mercaptans generate gums; (3) Esterification: aromatics, heterocyclic nitrogen, and benzenethiols generate sediment. Therefore, during the...
