Abstract

The invention relates to a preparation process for microemulsified diesel oil. The raw materials include, by mass, 60-77% of 0# diesel oil, 5-12% of a compound emulsifier, 4-10% of n-butanol, and 10-20% of water. The compound emulsifier is a mixture of sodium heavy alkyl benzene sulfonate, sodium dodecyl benzene sulfonate and 2-(pentadecanoyloxy)ethanesulfonic acid ester. The preparation process includes: adding the compound emulsifier into water, conducting stirring till complete dissolution, under ultrasonic condition, adding the product into a mixed solution of diesel oil and n-butanol dropwise, and after complete adding, conducting ultrasonic treatment, thus obtaining the microemulsified diesel oil. The process is simple. The prepared microemulsified diesel oil is transparent, has viscosity, flash point and condensation point similar to ordinary diesel oil, has stable time for over 6 months, and is convenient for storage and transportation. The price of the microemulsified diesel oil is lower than ordinary diesel oil on the market, can be used as commercial diesel oil, and has good economic benefits.

Description

technical field [0001] The invention belongs to the technical field of emulsified diesel oil. Specifically relates to a preparation process of micro-emulsion diesel oil. Background technique [0002] For more than half a century, with the rapid development of the modernization process of human society, energy sources have become increasingly exhausted and environmental pollution has become increasingly serious. It has become an inevitable development trend to explore new energy sources and improve existing energy sources to meet people's growing demand for energy. . The principle of fuel water mixing technology is that the mixed emulsion of fuel oil and water can produce a micro-explosion effect during combustion, causing secondary atomization of the fuel, making the fuel burn more fully, and greatly reducing the emission of harmful gases. Micro-emulsion diesel also has a good flame retardant effect, which can effectively reduce the tendency of flame spread and make the u...
