A kind of vehicle environment-friendly methanol diesel and preparation method thereof

Abstract

An environment-friendly methanol diesel for vehicles and a preparation method thereof, the weight percent composition is: 5-20% of methanol, 20-80% of diesel, 5-20% of composite additives, and 10-40% of auxiliary materials. Its preparation method is as follows: under normal temperature and pressure conditions, firstly add compound additives to methanol and fully dissolve to make denatured methanol; then make auxiliary materials according to the proportion of auxiliary materials; finally add denatured methanol and auxiliary materials according to the proportion In the diesel oil, after fully stirring and mixing for 10-60 minutes, the environmentally friendly methanol diesel for vehicles is obtained. On the premise of ensuring the cetane number of diesel oil, this product can greatly reduce the emission of pollutants.

Description

technical field

[0001] The invention belongs to the technical field of preparation of alcohol substitute fuels, and in particular relates to a vehicle-used environment-friendly methanol diesel and a method for preparing the diesel. Background technique

[0002] In recent years, with the rapid development of my country's economy, the demand for oil continues to grow. Since 1993, my country has become a net importer of petroleum. In 2009, the proportion of my country's crude oil imports has exceeded 52%. Diesel engines have the advantages of high thermal efficiency and good fuel economy. They are more and more widely used in automobiles, and the shortage of diesel supply is getting bigger and bigger. Diesel engines contain a large number of particulates in their exhaust, and their mass concentration is 30-80 times that of gasoline engines. These particles are mainly composed of black carbonaceous substances with a very low sedimentation rate and can be suspended in the atmos...
