Problems solved by technology

[0005] Although there are many kinds of methanol diesel oil in the prior art, there are obvious deficiencies: 1. The price of methanol diesel oil adding co-solvent is relatively high; 2. It is easy to stratify when placed; The cetane number is low, and it is difficult to meet the standard for diesel engines (greater than 50); 5. Methanol diesel has corrosion and swelling problems on the engine oil circuit and cylinder metal parts, as well as on the rubber and plastic parts of the connecting pipeline.

Abstract

The invention relates to a methanol diesel oil microemulsion and a preparation method thereof. According to a microemulsification theory, the methanol diesel oil microemulsion is prepared from the following base materials in parts by weight: 15-50 parts of modified methanol, 0.1-5 parts of surfactant, 40-60 parts of diesel oil and 8-20 parts of cosolvent, and the like. Compared with the prior art, the invention solves the technical problems of bad stability, low flash point, low thermal value, delamination in contact with water, and the like in the traditional methanol diesel oil, and has theadvantages of simple preparation process, vast methanol additive amount, favorable combustion performance, emission index meeting environmental requirements, and the like.

Description

technical field [0001] The invention relates to an alternative fuel that can be directly used in diesel engines, in particular to a methanol diesel microemulsion and a preparation method thereof. Background technique [0002] With the rapid development of the national economy and the improvement of people's living standards, my country's demand for energy is increasing day by day, and the consumption of liquid fuels that use petroleum as raw material continues to increase. At the same time, traditional oil resources are increasingly scarce. According to statistics, the recoverable amount of oil in the world is about 120 billion to 140 billion tons. According to the estimate of the world's annual oil consumption of 3 billion to 3.2 billion tons, it can last for 40 to 50 years. Therefore, research and development of alternative fuels is imperative. The development trend of international vehicle fuels and my country's energy policy clearly point out that vehicles should gradu...
