Problems solved by technology

[0002] Diesel oil is extracted from petroleum. Due to the current shortage of petroleum resources, a lot of artificial synthetic diesel oil has been produced. At present, the technology of replacing diesel oil with water, that is, the technology of emulsified diesel oil, but most of them cannot be popularized and applied because of the following shortcomings:
[0003] 1. The current emulsified diesel oil has short shelf life, poor stability, easy oil and water stratification, and high sulfur content;
[0004] 2. High cost, easy to corrode the engine, easy to retain impurities in the machine, and it is difficult to meet the requirements of commercialization, which limits the promotion and application;
[0005] 3. It is easy to produce chemical reactions with other commodity diesel oil, and the safety is poor;
[0006] 4. The current emulsified diesel oil is an additive of diesel oil, but there is no emulsified diesel oil that can be used directly

Abstract

Disclosed is a condensed emulsive diesel oil, comprising of the following ones: diesel oil 30-81, alkylnaphthalene 1-8, water 5-35, ethanolamine 0.3-11, oleic acid 4-35, or ethyl nitrate 0.05-0.6, potassium hydroxide or sodium hydroxide,The invention has log guarantee period which can be more than three years, good stability, no delamination of oil and water after being placed for a long period, low content of sulpher, can be used directly as well as being mixed with pure diesel oil; and it has low productive cost, simple preparing technique, low degree of corrosion; by using the invention, the service life of motor can be prolonged, with high of efficiency. It can be applied in industrial burning, equipments in auto, ship and generating set, with high ratio of performance and price, as diesel oil additive, it can decrease the drainage of harmful gas, make the oil-saving rate to be 20%, has bright future in market.

Description

technical field [0001] The invention relates to a concentrated emulsified diesel oil, in particular to a concentrated emulsified diesel oil which has the same color and transparency as pure diesel oil, has a long shelf life, excellent safety and stability, and is convenient to use. Background technique [0002] Diesel oil is extracted from petroleum. Due to the current shortage of petroleum resources, a lot of artificial synthetic diesel oil has been produced. At present, the technology of replacing diesel oil with water, that is, the technology of emulsified diesel oil, but most of them cannot be popularized and applied because of the following shortcomings: [0003] 1. The current emulsified diesel oil has short shelf life, poor stability, easy oil and water stratification, and high sulfur content; [0004] 2. High cost, easy to corrode the engine, easy to retain impurities in the machine, and it is difficult to meet the requirements of commercialization, which limits the ...
