Problems solved by technology

[0004] For this reason, the applicant once proposed on November 7, 2003 an invention patent titled "additive for emulsified diesel oil and its preparation method", the patent number is 200310103533.4, which discloses a kind of additive for emulsified diesel oil Oil-based additives and water-based additives. Among them, the disadvantages of water-based additives are: diesel oil emulsified with this additive has poor corrosion resistance and cannot meet the national standards; diesel oil emulsified with this additive is easy to change color when it comes into contact with water , causing water out, affecting the combustion performance of emulsified diesel oil; the diesel emulsified by this additive has a fast oxidation speed, and the oil product is easy to turn black, which affects the combustion performance and finally affects the power performance of diesel oil

Abstract

The invention relates to biosynthesis diesel oil water craft additive belongs to diesel oil emulsification technique. Its each component is triethanolamine, monoethanolamine, cyclohexylamine, ethylene glycol monoethyl ether, isopropyl alcohol, cyclohexylamine carbonate, benzene parallel tri-nitrogen azole, methanol, ammonia water, and ethylene glycol. Its manufacturing method is that all of the operation do in proportion and mix them as the following order that one is methanol, benzene parallel tri-nitrogen azole, cyclohexylamine carbonate, ethylene glycol monoethyl ether, isopropyl alcohol; the other is triethanolamine, monoethanolamine, cyclohexylamine. Both of them are added into the ammonia water; and the ethylene glycol is added. It is used to make emulsification diesel oil. It has strong erosion and freezing resistance, and can promote oil product stable and dissolve each other.

Description

technical field [0001] The invention relates to a water-based additive for biosynthesis of diesel and a preparation method thereof, belonging to the technical field of diesel emulsification. Background technique [0002] Since 1913, HopKinson of the University of Cambridge in the United Kingdom proposed the combustion technology of diesel oil mixed with water. It has a history of 100 years. However, due to various reasons in the development of the chemical industry, the emulsification technology has also been hindered to some extent. Diesel water-mixed emulsions are mostly white liquids with large water particles, which are easy to stratify and bleed out, and have a short storage time. Therefore, there are many problems in popularization and application. On the other hand, in pursuit of the improvement of emission standards, many researchers are one-sidedly pursuing economic benefits. The water content of diesel oil mixed with water is too high, resulting in insufficient co...
