Problems solved by technology

Due to the current shortage of oil resources, a lot of synthetic diesel oil has been produced. At present, the technology of replacing diesel oil with water is emulsified diesel technology, but the current emulsified diesel oil has a short shelf life, poor stability, high sulfur content, low water content, and high cost. , which limits its development
For example, the Chinese patent No. ZL200410082835.2 discloses the technology of "A Concentrated Emulsified Diesel Oil, Its Preparation Method and Its Use". This patent also has technical problems of poor stability, complex production process, and difficult control. Sex also needs to be further improved

Abstract

The invention relates to concentrated emulsified diesel fuel and a preparation method thereof, wherein the concentrated emulsified diesel fuel is long in shelf life and low in cost and is prepared by the following raw materials by weight parts: 50-80 of diesel, 0.5-1 of cyclohexylamine, 0.5-2 of ethanolamine, 0.03-0.08 of water and hydrazine, 8-17 of oleic acid or fatty acid, 0.01-0.08 of ferrocene, 0.1-1 of isooctyl nitrate or amyl nitrate, 5-10 of ethanol, 4-15 of solvent oil and 10-30 of water. The concentrated emulsified diesel fuel is long in service life which is 6 years, has no emulsion breaking, is good in stability, can be used directly, also can be used by being mixed with national-standard diesel in any proportion, and further has the advantages of being simple in production process, easy to control, low in sulphur content and good in flowability, and the quality of the diesel is free of influence caused by secondary water adding.

Description

technical field [0001] The invention relates to a concentrated emulsified diesel oil, in particular to a concentrated emulsified diesel oil with long shelf life and good miscibility with water and a preparation method thereof. Background technique [0002] Diesel, also known as oil residue, is an oily product after petroleum refining. Diesel fuel can be used as fuel for vehicles, tanks, airplanes, tractors, ships, railway vehicles and other vehicles or other machinery, and can also be used for power generation and heating. The most important properties of diesel are ignitability and fluidity. Diesel is more efficient, and if it replaces gasoline in large quantities, it can reduce oil consumption and carbon dioxide emissions. Due to the current shortage of oil resources, a lot of synthetic diesel oil has been produced. At present, the technology of replacing diesel oil with water is emulsified diesel technology, but the current emulsified diesel oil has a short shelf life, ...
