Methanol-diesel and preparation method thereof

Abstract

The invention relates to methanol-diesel and a preparation method thereof, and the methanol-diesel contains the following components in parts by weight: 30-80 parts of methanol, 20-60 parts of diesel and 10-50 parts of additives. The preparation method comprises the following steps: adding the additives into a reactor successively, and stirring until a uniform and steady transparent solution is formed, thus obtaining an additive mixed solution; and then mixing the methanol with 0# diesel, then adding the prepared additive mixed solution of a certain proportion under intense stirring, and thenstirring until the solution is clear and transparent, thus obtaining the prepared methanol-diesel. Compared with the prior art, the stability of the methanol-diesel is improved, the flash point and the combustion efficiency of the methanol-diesel are enhanced, and the mixed methanol-diesel is transparent and steady, has no milky or stratified situation and can be stored for a long time; and when in use, the methanol-diesel can be directly used, the structure of the existing engine does not need to be changed, and the performance indexes can all meet the requirements of commercial diesel.

Description

technical field [0001] The invention relates to a methanol diesel, in particular to the material ratio of methanol diesel and additives and a preparation method thereof. Background technique [0002] With the rapid development of the global economy, the demand for oil in countries around the world is increasing day by day, but oil is a non-renewable energy source, and the world's oil reserves are decreasing year by year. The shortage of oil has become a long-term pressure restricting the development of the world economy. At present, the main purpose of petroleum is to produce gasoline and diesel for use in internal combustion engines. However, due to the low combustion efficiency of internal combustion engines, a large amount of black carbon-containing particles in the exhaust are suspended in the air, resulting in serious environmental pollution. Sulfur dioxide and polycyclic benzene carcinogens have caused great harm to human health. Therefore, research and development of...

AI Technical Summary

Problems solved by technology

[0005] A variety of methanol-diesel blended fuels have been developed at home and abroad, but there are more or less problems. For example, the early methanol-diesel fuel needs to be refitted to the diesel engine and add auxiliary facilities before it can be used. This is the reason for the promotion and application of methanol-diesel. brought some difficulty

The methanol diesel fuel developed by the German Federation has a low flash point and is easy to catch fire. The price of the co-solvent is high and the stability is poor. It will be emulsified and stratified when it comes into contact with a small amount of water.

Chinese patent CN101033414A has solved the problems such as corrosion, swelling, cold start difficulty, thermal air resistance, and power drop encountered in the use of existing methanol diesel, but the additive raw materials prepared by it are expensive, which leads to The cost of methanol diesel is higher

[0006] The methanol diesel in the prior art has obvious deficiencies: poor stability and easy stratification, especially when a large proportion of methanol is added, there are problems in the stability, flash point, and combustion performance of methanol diesel, which still need to be further solved
