Alcohol ether diesel and preparation thereof

Abstract

The invention discloses an alcohol ether diesel, comprising ingredients having the following parts by weight respectively: finished diesel, isobutanol, refined acidified oil, methanol, 200<#> solvent oil, petroleum acid, dimethyl tert-butyl ether and catalytic incendiary agent. The invention realizes the esterification reaction between methanol and fatty acid under normal temperature, saves energy and simplifies the production process for fatty acid methyl ester; the methanol, which is not subjected to the esterification reaction, is coupled by the isobutanol so as to avoid the methanol from existing in the products in the manner of direct ionization, thus further improving the flash point of the alcohol ether diesel.

Description

technical field [0001] The invention relates to alcohol ether diesel oil and a preparation method thereof. Background technique [0002] Since the reform and opening up, my country's national economy has continued to develop. The automobile industry, like other industries, has a good production and marketing form and is booming. At present, the annual consumption of crude oil has reached more than 200 million tons, the annual import volume has reached 70 million tons, and the annual import volume of refined oil has reached 30 million tons. As mentioned above, under the pressure of huge demand, my country's energy security has become a serious problem, all of which make people urgently need to find new alternative energy sources. [0003] At present, there are many technologies related to the development of petroleum substitute engineering products in China. At this stage, the method of adding a low proportion of methanol to gasoline is generally used, that is, methanol gasoli...

AI Technical Summary

Problems solved by technology

Because the mixed methanol is simply a mixture of methanol and gasoline, and the proportion is low, and because the latent heat of vaporization of livestock is large, the combustion value is low, and the consumption is large, the low proportion of mixed combustion cannot achieve the double technology of fully utilizing and saving resources. However, increasing the proportion of methanol usage will face problems such as low combustion efficiency, high fuel consumption, and reduced power performance.
