AI Technical Summary

Problems solved by technology

The water droplets in the emulsified diesel have a large particle size, are unstable, and are easy to stratify. After the first ignition of the emulsified diesel, once the oil and water remaining in the cylinder are stratified, it will make it difficult to start again.

Abstract

The invention relates to the field of petroleum and particularly relates to micro-emulsified diesel oil. The micro-emulsified diesel oil is prepared from the following components in parts by weight: 60-80 parts of 0# diesel oil, 8-15 parts of deionized water, 2-5 parts of block polymeric surfactant, 0.5-4 parts of sodium dioctyl sulfosuccinate, 1-5 parts of 1, 4-butanediol, 2-5 parts of n-butanol, 2-6 parts of isopropanol and 3-6 parts of isopropyl ketone. A micro-emulsified diesel oil additive provided by the invention has the following advantages that the block polymeric surfactant and sodium dioctyl sulfosuccinate as a cosurfactant are compounded, so that the micro-emulsification effect is better, a system is more stable, the micro-emulsified diesel oil prepared from the block polymeric surfactant and sodium dioctyl sulfosuccinate is longer in storage time up to over six months, free of layering, oil water separation and sediments, convenient to store and transport and high in practical value; when the micro-emulsified diesel oil burns, the discharge value of pollution gases is reduced during low-oxygen combustion.

Description

technical field [0001] The invention relates to the petroleum field, in particular to a microemulsion diesel oil. Background technique [0002] In recent years, diesel water emulsification has developed rapidly as an important fuel-saving and pollution-reducing technology. Compared with ordinary diesel oil, emulsified diesel oil has the characteristics of good combustion performance, low energy consumption, and less pollution. At the same time, the emulsified diesel oil not only does not cause corrosion and increased wear to the diesel engine, but also acts as a cleaning agent, which can reduce the maintenance cost of the diesel engine. For emulsified diesel oil, the most prominent problem at present is the stability problem. The water droplets in the emulsified diesel have a large particle size, are unstable, and are easy to stratify. After the emulsified diesel is ignited for the first time, once the oil and water remaining in the cylinder are stratified, it will make it...
