Abstract

The invention discloses methanol diesel oil and a preparation method thereof. The methanol diesel oil is prepared from, by weight, 23-27 parts of 200 # solvent oil, 28-32 parts of common first-vacuumdiesel oil, 15-17 parts of methyl tertiary butyl ether, 26-32 parts of coal tar, 28-34 parts of aviation kerosene and 15-18 parts of methanol. The preparation method of the methanol diesel oil comprises the following steps that 1, the methyl tertiary butyl ether and the methanol are weighed according to the proportion respectively, the weighed methyl tertiary butyl ether and the methanol are mixedand uniformly stirred, and a methanol-based mixed solution is further prepared; 2, the 200 # solvent oil, the common first-vacuum diesel oil, the coal tar and the aviation kerosene are weighed respectively according to the proportion, the weighed 200 # solvent oil, the common first-vacuum diesel oil, the coal tar and the aviation kerosene are sequentially added into the methanol-based mixed solution obtained in step 1 and stirred evenly, and the methanol diesel oil is obtained. The prepared methanol diesel oil is good in stability, free of layering and good in combustion performance.

Description

technical field [0001] The invention belongs to the technical field of diesel oil, and relates to a methanol diesel oil and a preparation method thereof. Background technique [0002] The energy utilization rate of coal in traditional power plants can reach 40-44%, and the energy utilization rate of coal in combined heat and power generation can reach 70%. The technology that uses more energy than combined heat and power generation is coal-electricity polygeneration technology, which enables The energy utilization efficiency of coal can reach 85%. In addition to power generation and heat supply, methanol is also produced. Methanol is a basic chemical raw material. In addition to providing fuel for internal combustion engines, it can also extend to the downstream industrial chain. Therefore, the development of methanol vehicles is closely related to the clean, efficient and comprehensive utilization of coal resources in my country. This is the basic starting point for my coun...
