Problems solved by technology

Diesel oil is extracted from petroleum. Due to the current shortage of petroleum resources, a lot of synthetic diesel oil has been produced. At present, there is a technology to replace diesel oil with water, which is emulsified diesel technology. However, the current emulsified diesel oil has a short shelf life, poor stability, and sulfur content. High volume, low water content and high cost limit its development
For example, the Chinese patent whose patent number is ZL200410082835.2 discloses the technology of "a kind of concentrated emulsified diesel oil, its preparation method and its application". This patent also has the technical problems of poor stability and high cost, and its shelf life and fluidity also need to be further improved. supply

Abstract

The invention relates to concentration emulsified diesel fuel, in particular to concentration emulsified diesel fuel long in shelf life and low in cost and a preparation method thereof. The concentration emulsified diesel fuel is prepared through the following raw materials, parts by weight, 20-40 parts of diesel fuel, 16-22 parts of oleic acid, 5-12 parts of methanol, 2-6 parts of sodium nitrate, 26-36 parts of water, 5-14 parts of ethanolamine, 0.3-0.8 part of isooctyl nitrate or amyl nitrate and 0.3-0.8 part of ethylene glycol. Color and transparency of the concentration emulsified diesel fuel are the same as the diesel fuel, shelf life is long, emulation of the emulsified diesel fuel placed for more than 7 years can not be broken, stability is good, and a phenomenon of stratification of oil and water does not occur after the concentration emulsified diesel fuel is placed for 7 years. Through testing data verification, sulphur content is low, water content is high, production cost is greatly reduced, preparation process is simple, and corrosion level is low. The concentration emulsified diesel fuel is low in sulphur content and kinematic viscosity and can enable the diesel fuel to be burned completely when used as a diesel fuel additive, therefore emission quantity of harmful gas is reduced.

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 low cost and a preparation method thereof. Background technique [0002] Diesel, also known as oil residue, is an oily product after petroleum refining. It consists of a mixture of different hydrocarbons. Its main components are alkanes, cycloalkanes or aromatics containing 10 to 22 carbon atoms. Its chemical and physical properties are between gasoline and heavy oil, its boiling point is between 170°C and 390°C, and its specific gravity is 0.82~0.845kg / l. 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 con...
