Embodiment 1

[0036] Example 1 (Dosage is in parts by weight):

[0037] Modified methanol is composed of the following components:

[0038] Methanol 85-100

[0039] Acetone 1-9

[0040] Methyl tert-butyl ether 1-3

[0041] Adding acetone to methanol increases the compatibility of methanol and gasoline; adding methyl tert-butyl ether improves the explosive power of methanol and makes methanol burn more fully.

[0042] The preparation method of the present invention for preparing the above components is:

[0043] 1. Pour the measured acetone into the container under normal temperature and pressure;

[0044] 2. Pour the measured methanol into the acetone container, and stir evenly while injecting. The stirring time is about 4.5-5.5 minutes;

[0045] 3. Pour the measured methyl tert-butyl ether into the above-mentioned container with two components and continue to fully stir for 4.5-5.5 minutes to obtain modified methanol.

[0046] The applications of the above-mentioned modified methanol are:

Embodiment 2

[0049] Example 2 (Dosage is the number of parts by weight):

[0050] Methanol 90-96

[0051] Acetone 3-6

[0052] Methyl tert-butyl ether 2-2.5

[0053] The above-mentioned components are prepared by the preparation method of the present invention as in Example 1.

[0054] The application of the above-mentioned modified methanol is the same as in Example 1.

Embodiment 3

[0055] Example 3 (Dosage is the number of parts by weight):

[0056] Methanol 95

[0057] Acetone 4

[0058] Methyl tert-butyl ether 2

[0059] The above-mentioned components are prepared by the preparation method of the present invention as in Example 1.

[0060] The application of the above-mentioned modified methanol is the same as in Example 1.

Abstract

The present invention discloses a modified methyl alcohol which can be partially substituted for fuel oil, its preparation method and application. The methyl alcohol, acetone and methyl-tert-butyl ether are proportioned according to a certain ratio, then progressively added into a container, stirred and mixed so as to obtain modified methyl alcohol, it can be mixed with general gasoline, can be substituted for 50% of gasoline. The modified methyl alcohol is mixed with biological diesel oil according to the radio of 1:1, then it can be substituted for 80% of general diesel oil. The product quality of synthetic fuel product obtained by mixing modified methyl alcohol with gasoline or diesel oil is stable, its combustion is fuel, and its tail gas discharge cleaning rate is high.

Description

Technical field [0001] The invention belongs to a kind of fuel, in particular to a modified methanol that can be mixed with gasoline or diesel and can partially replace gasoline or diesel. Background technique [0002] At present, the crude oil used to refine gasoline and diesel is in short supply worldwide, especially in our country. In recent years, the import volume of crude oil has reached more than 30%. The shortage of crude oil has caused the price to continue to rise, so the price of gasoline and diesel has also risen. . In order to solve the problem of gasoline and diesel shortage and high prices, my country is constantly studying the use of synthetic fuels to partially replace gasoline and diesel. [0003] In terms of gasoline substitution, ethanol used to be the target of choice. According to the China Petrochemical News, Nanyang City, Henan Province issued a document stipulating that from March 8, 2003, all gasoline containing 10% ethanol will be used; China’s latest I...
