Abstract
The invention discloses a mixed micro-emulsified diesel oil emulsifying auxiliary agent, which comprises SPAN20 sorbitan monolaurate, SPAN40 sorbitan monopalmitate, SPAN60 sorbitan monostearate, SPAN65 sorbitan tristearate, SPAN80 sorbitan monooleate, Tween20 polyoxyethylene sorbitan monolaurate, Tween40 polyoxyethylene sorbitan monopalmitate and Tween61 polyoxyethylene sorbitan monostearate according to concentration percentage, and the production flow of the mixed micro-emulsified diesel oil emulsifying auxiliary agent emulsified diesel oil is as follows: s1, S2, S3 and S4. According to the invention, the prepared mixed emulsifier forms a consistent interface film on the oil/water section, the mixed emulsifier enables the reduction of the interfacial tension to be lower, the interface adsorption to be increased, the molecular arrangement to be tighter, the strength of the composite interface film to be greatly improved, the stability of the emulsifier diesel oil is improved, and the preparation method reduces the particulate matter emission, reduces the nitrogen oxide emission, and reduces the smoke emission and the carbon dioxide emission.
Description
Technical Field
The invention relates to the technical field of diesel oil preparation by using an emulsifier, in particular to a mixed micro-emulsified diesel oil emulsifying auxiliary agent and a production process thereof.
Background
The diesel oil is a light petroleum product, is a mixture of complex hydrocarbons (with carbon atoms of about 10-22), is a diesel fuel, and is mainly prepared from diesel oil fractions produced in the processes of crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, petroleum coking and the like; the diesel oil can also be prepared by processing shale oil and liquefying coal, is divided into two categories of light diesel oil (the boiling point range is about 180-370 ℃) and heavy diesel oil (the boiling point range is about 350-410 ℃), is widely applied to large vehicles, railway locomotives and ships, and the most important purpose of the diesel oil is to be used for diesel engines of vehicles and ships. Compared with gasoline, diesel fuel has high energy density and low fuel consumption, but exhaust gas contains many harmful components (NO, particulate matter, etc.).
The traditional diesel oil production process is easy to cause more particulate matter emission and more carbon dioxide emission, and is not environment-friendly enough, so that a mixed micro-emulsified diesel oil emulsifying auxiliary agent and a production process thereof are provided.
Disclosure of Invention
Therefore, the invention aims to provide a mixed micro-emulsified diesel oil emulsification aid and a production process thereof, an interfacial film is formed on the cross section of oil and water by the prepared mixed emulsifier, the mixed emulsifier enables the interfacial tension to be reduced lower, the interfacial adsorption to be increased, the molecular arrangement to be tighter, the strength of the composite interfacial film is greatly improved, the stability of the emulsifier diesel oil is improved, the particulate matter emission is reduced, the nitrogen oxide emission is reduced, the smoke emission and the carbon dioxide emission are reduced, and the emission reduction effect is obvious.
To solve the above technical problem, according to an aspect of the present invention, the present invention provides the following technical solutions:
a mixed micro-emulsified diesel oil emulsifying additive comprises the following components in percentage by concentration:
a process for preparing the emulsified diesel oil from the mixed microemulsified diesel oil as claimed in claim 1, which comprises the following steps,
