Problems solved by technology

Methanol diesel is such a new energy source, which has certain applications in daily life, but the existing methanol diesel is simply mixed with a certain proportion of methanol in diesel oil, which is in the case of a low proportion of 3-5%. However, with the increase of the proportion of methanol, many problems such as low heating value of methanol, insufficient power, high fuel consumption, difficult cold start, high temperature air resistance, poor stability, corrosion and swelling, and mutual solubility with diesel oil will occur. Exposed one by one, seriously affecting the use effect

Embodiment 1

[0032] Embodiment 1: Provide a kind of preparation process of methanol synthetic diesel oil, the main steps of this process are as follows:

[0033] (1) Preparation of Mixture A: After adding methanol and amine water to naphthenic acid, carry out stirring reaction for 20 minutes, and cut the oil by high-speed oil shearer for 10 minutes, and then obtain Mixture A in brown-red transparent liquid state. Its composition percentage of each constituent is:

[0034] Naphthenic Acid 60%

[0035] Amine water 20%

[0036] Methanol 20%

[0037] The aforementioned naphthenic acid is a crude acid having an acid value of 115. The acid value and color of naphthenic acid will affect the amount of naphthenic acid and the color and viscosity of methanol-synthesized diesel, which can be adjusted according to cost and use during production.

[0038] (2) Preparation of Mixture B: Mix acetone, 8-hydroxyquinoline, n-ethane, polyvinylpyrrolidone, isooctyl nitrate and ethanolamine directly with ea...

Embodiment 2

[0059] Embodiment two: Compared with embodiment one, preparation process is identical, and wherein the percentage of each constituent of C mixture is identical, and difference is only in:

[0060] The composition percentage of each constituent of A mixture is:

[0061] Naphthenic acid 80%

[0062] Amine water 10%

[0063] Methanol 10%

[0064] The composition percentage of each constituent of B mixture is:

[0065] Acetone 15%

[0066] 8-Hydroxyquinoline 15%

[0067] n-Ethane 15%

[0068]Polyvinylpyrrolidone 15%

[0069] Isooctyl Nitrate 20%

[0070] Ethanolamine 20%

[0071] The composition percentages of A mixture, B mixture, C mixture, diesel oil and water are:

[0072] Mixture A 30%

[0073] Mixture B 0.1%

[0074] Mixture C 0.1%

[0075] Diesel 50%

[0076] water 20%

[0077] The produced methanol-synthesized diesel product and its use effect are completely consistent.

Embodiment 3

[0078] Embodiment three: compared with embodiment one, preparation process is identical, and the percentage of each component of A mixture, B mixture, C mixture is all the same, and difference only is:

[0079] The composition percentages of A mixture, B mixture, C mixture, diesel oil and water are:

[0080] Mixture A 20%

[0081] Mixture B 0.1%

[0082] Mixture C 0.1%

[0083] Diesel 60%

[0084] water 20%

[0085] The produced methanol-synthesized diesel product and its use effect are completely consistent.

Abstract

The present invention discloses a confection process of synthesized methanol diesel. The process mainly includes the following steps: (1) the confection of A mixture: naphthenic acid is added with methanol and amine water, stirred for 10 to 20 minutes and sheared by a high-speed shearing machine for 10 minutes so as to obtain the brownish red liquid A mixture; (2) the confection of B mixture: acetone, 8- hydroxyquinoline, positive ethane, polyethylene menthanone, isooctyl ester nitrate and ethanol amine are directly mixed and added with an appropriate amount of diesel or coal oil as the auxiliary agent, thus obtaining the B mixture after even stirring; (3) the confection of C mixture: ferrocene, polyisobutylene and polyethylene-ester acid ethane are directly mixed and added with an appropriate amount of diesel or coal oil as the auxiliary agent, thus obtaining the C mixture after even stirring; (4) the A mixture is added with water and fully stirred, then the B mixture, the diesel and the C mixture are fully stirred after ultrasonic grinding and oil shearing by the high-speed shearing machine for more than ten minutes and finally the confection is completed after several minutes of oil shearing by the high-speed shearing machine. The synthesized methanol diesel prepared by the process has the beneficial technical effects of energy saving, environmental protection, no corrosion, wide application range, stable quality, simple production, etc., which is worth promoting.

Description

technical field [0001] The invention relates to the technical field of environmental protection energy, in particular to a process for preparing methanol-synthesized diesel. technical background [0002] The development of environmentally friendly new energy as an alternative fuel is the need of the national energy strategy and environmental strategy, as well as the need of the sustainable development of my country's industry and even the entire society. Methanol diesel is such a new energy source, which has certain applications in daily life, but the existing methanol diesel is simply mixed with a certain proportion of methanol in diesel oil, which is in the case of a low proportion of 3-5%. However, with the increase of the proportion of methanol, many problems such as low heating value of methanol, insufficient power, high fuel consumption, difficult cold start, high temperature air resistance, poor stability, corrosion and swelling, and mutual solubility with diesel oil ...
