Problems solved by technology

[0002] At present, there are very few methanol diesels sold in the market. The key is that the production technology is not up to standard. The main reason is that the anhydrous methanol is used. On the one hand, the cost is too high; on the other hand, the products produced have emulsification, swelling, delamination, corrosion, Problems such as air resistance and lack of power

Embodiment 1

[0038] 1. Put 0.8% ethanolamine and 0.6% naphthenic acid into the prepared industrial methanol and mix evenly to make it a denatured methanol for use;

[0039] 2. Put 8% naphthenic acid into diesel and mix evenly to obtain diesel mixture for later use;

[0040] 3. Select the following raw materials to prepare diesel oil modifier:

[0041] Alkylphenol Ethoxylates 75%

[0042] Dimethyl carbonate 16%

[0043] Ethyl Oleate 6%

[0044] p-tert-Butylphenol 3%

[0045] 4. Add the raw materials in step 3 into the container according to the volume percentage and in order, and stir for 20-30 minutes until uniform, and then the methanol diesel modifier is prepared for use;

[0046] 5. Add 70% diesel oil mixture to 25% denatured methanol and stir well, then add 5% diesel modifier to make it fully mixed to produce methanol diesel product.

Embodiment 2

[0048] 1. Put 1.2% ethanolamine and 1% naphthenic acid into the prepared industrial methanol and mix evenly to make it a denatured methanol for use;

[0049] 2. Put 12% naphthenic acid into the prepared diesel oil and mix evenly to obtain a diesel mixture for later use;

[0050] 3. Select the following raw materials to prepare diesel oil modifier:

[0051] Alkylphenol Ethoxylates 75%

[0052] Dimethyl carbonate 16%

Abstract

The invention discloses a manufacturing method for preparing methanol diesel fuel from industrial methanol. The method comprises the following steps of: putting ethanolamine and naphthenic acid into the industrial methanol according to a certain proportion and mixing to obtain denatured methanol for later use; selecting alkylphenol ethoxylates, dimethyl carbonate, ethyl oleate and para-tert-butyl phenol according to a proportion, sequentially adding the alkylphenol ethoxylates, the dimethyl carbonate, the ethyl oleate and the para-tert-butyl phenol into a container and stirring for 20 to 30 minutes so as to obtain a methanol diesel fuel modifier for later use; and adding 75 percent diesel fuel mixed liquor into 20 percent denatured methanol, stirring fully and uniformly, adding 5 percent diesel fuel modifier and fully mixing so as to obtain finished methanol diesel fuel. A methanol diesel fuel product has the advantages of no delamination, high stability, no corrosion, no swelling, no emulsification, high explosive force, convenient use, readily available raw materials, low manufacturing cost and easy popularization.

Description

technical field [0001] The invention relates to a method for producing methanol diesel by using industrial methanol, which can effectively improve the stability of methanol diesel and greatly reduce carbon emissions. Background technique [0002] At present, there are very few methanol diesels sold in the market. The key is that the production technology is not up to standard. The main reason is that the anhydrous methanol is used. On the one hand, the cost is too high; on the other hand, the products produced have emulsification, swelling, delamination, corrosion, Air resistance and lack of power and other issues. Contents of the invention [0003] In view of the above-mentioned present situation, the object of the present invention is to provide a kind of manufacturing method of producing methanol diesel with industrial methanol, which can be operated under normal temperature and pressure, and the industrial methanol is denatured and fully mixed with the pre-prepared die...
