Problems solved by technology

[0008] 2. The problem of low flash point of methanol diesel
[0009] The flash point of methanol is low (11-12°C), which is far from the flash point of diesel (55°C). After methanol and diesel are mixed, the resulting blended fuel oil is still easy to catch fire at low temperature, which is easy to burn due to poor combustion. Synchronization causes unstable working conditions of the compression ignition engine, and also brings unsafe transportation and storage
[0010] 3. The problem of low cetane number of methanol diesel
[0012] 4. The problem of emulsification and stratification of methanol diesel and water
These formulas have solved the problem of methanol-diesel miscibility to a certain extent, but there are still problems such as insufficient mutual solubility, easy layering, insufficient clarity, or defects in cost performance

Embodiment 1

[0059] Prepare a simple combination of low-carbon fuel oil 1, additive 1 made 130.0g, used to blend 1100g methanol 2, additive 1 formula includes the following components and content:

[0060] Emulsifier 50g, including oleic acid 30g, Span 80 15g, OP-105g;

[0061] 20g of pH buffering agent, including 10g of sodium petroleum sulfonate and 10g of barium petroleum sulfonate;

[0062] Isobutanol, 20.5g;

[0063] Tricresyl phosphate 10g;

[0064] Toluene 10g;

[0065] Dimethyl carbonate 10g;

[0066] Isooctyl nitrate, 6.1g;

[0067] The auxiliary emulsifying dispersant is combined with 1.2g of dimethyl succinate and 1.0g of T161A product of polyisobutylene derivative series;

[0068] Antioxidants were selected from N-phenyl-α-naphthylamine (T531) and 2,6-di-tert-butylα-dimethylamino-p-cresol 0.6g each to combine.

[0069] The above-mentioned raw materials are commercially available common raw materials, and the methanol meets the GB338-92 standard, and the purity is greater ...

Embodiment 2

[0077] Change the technique of Example 1 to prepare a low-carbon fuel oil 2 characterized by "oil phase methanol". The formula is characterized by the use of a large amount of oleic acid. The amount of emulsifier in Additive 1 is changed to 350g, of which 330g is oleic acid , Span 80 parts by weight 15g, OP-10 parts by weight 5g, and the remaining components and contents in the formula remain unchanged.

[0078] The preparation process is similar to that of Example 1. First, methanol and oleic acid 4 in component A are mixed evenly by weight to prepare the first type of component; other components are mixed evenly in the same weight ratio as in Example 1. Then add the first type of components to obtain low-carbon fuel oil 2 with a stable "water-in-oil" structure, which is a light yellow transparent liquid. In this example, methanol and oleic acid are mutually soluble and used as oil-phase fuel. The amount of methanol added is 72.3%. The modified oil-phase fuel is less corrosiv...

Embodiment 3

[0080] Prepare a simple combination of low-carbon fuel oil 3, make 100g of additives, and use to blend 4900g of methanol. The additives include the following components and contents:

[0081] Emulsifier 33g, including oleic acid 15g, Span-80 12g, TWEEN-80 6.0g;

[0082] 18.0g of pH buffering agent, including 12g of sodium petroleum sulfonate and 6g of barium petroleum sulfonate;

[0083] Isobutanol, 15g;

[0084] Tricresyl phosphate, 12g;

[0085] Ethylbenzene 10.0g, acetone 4g;

[0086] Isooctyl nitrate, 4.0g;

[0087] The auxiliary emulsifying dispersant is combined with 1.2g of dimethyl succinate and 0.8g of T161A product of polyisobutylene derivative series;

[0088] Antioxidants were selected from N-phenyl-α-naphthylamine (T531) and 2,6-di-tert-butyl α-dimethylamino-p-cresol 1.0 g each for combination.

[0089] The rest are the same as in Example 1, and a light yellow transparent liquid is finally obtained.

Abstract

The invention discloses a low-carbon fuel oil and a preparation method thereof. The low-carbon fuel oil comprises methanol or a modified complex thereof, and an additive, and the additive is prepared through a certain process of an oleic acid-Span series-Tween series (or OP-10) compounded three-in-one emulsifier, a sodium petroleum sulfonate and barium petroleum sulfonate combined pH buffer pair, isobutanol, tritolyl phosphate, an organic solvent, isooctyl nitrate, an emulsification dispersion aid and an antioxidant. The low-carbon fuel oil prepared through the method has the advantages of high cetane number, high flash point, low corrosivity, low emission and low cost, can be compounded with or dissolved in routine diesel oil for use, can be used in the fields of boilers, cars and boats by substituting the routine diesel oil, and has substantial energy saving and emission reduction effects.

Description

technical field [0001] The invention relates to the field of fuel oil, in particular to a combined additive used in the preparation of biofuel oil and biofuel compound diesel oil by methanol and its modified complex and a preparation method thereof. Background technique [0002] my country is short of oil and gas, relatively rich in coal resources, and has a wide source of coal-based alcohol ether fuels. Replacing petroleum resources with superior alcohol ether resources, or using alcohol ether fuels and petroleum mixtures to replace petroleum resources, is not only beneficial to the ecological environment, but also promotes the economy. sustainable development, and at the same time drive the development of related industries such as energy, chemical industry and automobile, which is conducive to the adjustment of industrial structure and the creation of new economic growth points. [0003] Many countries have promoted ethanol gasoline, and the amount of ethanol added to gaso...
