Problems solved by technology

Traditional gasoline and diesel detergents (referring to CN98103579.5) are simple in performance, and mainly focus on polyalkylamides and polyetheramines as main detergents and dispersants, which have single functions and are not obvious in fuel saving
In addition, the addition of traditional detergents to gasoline and diesel has a certain pollution reduction effect, but due to the addition of nitrogen compounds and other reasons, the content of nitrogen oxides will generally increase, and nitrogen oxides are the main culprits of photochemical smog in the urban atmosphere the culprit
[0003] After the diesel emulsifier (see CN02111285.1) is added, the formed emulsified diesel oil can reduce pollution and save fuel to a certain extent, but the instability of the emulsified diesel oil brings a lot of inconvenience to users
[0004] At present, there are many kinds of additives used in diesel and heavy oil, but most of them are mixed additives mainly based on metal ion catalysis (see CN02157655.6). Partial deposition is serious, even affecting normal combustion

Abstract

This invention relates to nano microemulsified oil process agent. It contains phase transfer catalyst, microemulsified aid, microemulsified surfactant, active deionization, and interfacial modifier. The preparation method is that confect the parent liquid from the former two components and the auxiliary liquid from latter three and then compound the process agent. And so it can improve the ability of hydrocarbon fuel such as gasoline, diesel oil and heavy oil. Moreover, it can reduce the surface tension of oil molecules by using interfacial modifier and can obviously advance the normal combustion, detergeney, microsystem lubricity, resistance to corrosion, and anti-oxygenation of the fuel. Additionally, of course, it reduces the force of attraction between oil molecules.

Description

technical field [0001] The invention relates to a nano micro-emulsion fuel oil synergist and a preparation method thereof, which is a synergist widely applicable to hydrocarbon fuels such as gasoline, diesel oil and heavy oil. Background technique [0002] The development of domestic fuel additives is relatively late, and the varieties are simple. They are mainly concentrated in single-function additives based on detergents, and there are many similar technologies. Traditional gasoline and diesel detergents (referring to CN98103579.5) are simple in performance, and mainly focus on polyalkylamides and polyetheramines as main detergents and dispersants, which have a single function and are not obvious in saving fuel. In addition, the addition of traditional detergents to gasoline and diesel has a certain pollution reduction effect, but due to the addition of nitrogen compounds and other reasons, the content of nitrogen oxides will generally increase, and nitrogen oxides are th...
