Problems solved by technology

[0003] However, because the production of biodiesel is limited by raw materials, biodiesel cannot really become an energy substitute. For this reason, many domestic enterprises and individuals have begun to study methanol diesel, but many problems have been encountered during the experimental use. The key is methanol diesel additives The technology has not been solved well, resulting in the existing methanol diesel not well solving the problems of stability, power and maintaining the original structure of the vehicle.

[0027] The raw material composition and proportion of methanol diesel additive are shown in the following table:

[0028] Table 1 Composition and dosage of raw materials

[0029] Unit:kg

[0030]

[0031] The concrete preparation method of methanol diesel additive is as follows:

[0032] Fully dissolve and mix refined methanol and ferrocene in a stirred tank at room temperature to form a homogeneous system to obtain denatured methanol; then add light diesel oil and dimethyl carbonate through a constant pressure funnel to continue stirring and mixing, and finally liquefied dimethyl ether , n-octanol, isooctyl alcohol, n-pentanol, maleic anhydride, primary amine and polyacrylamide were added, and fully stirred to form a homogeneous methanol diesel additive with a clear and transparent appearance. Store at a temperature of 20-25°C.

Abstract

The invention provides a methanol-diesel oil additive and a preparation method thereof. The methanol-diesel oil additive is mainly prepared from the following raw materials in parts by mass: 2.5-14 parts of methanol, 50-70 parts of light diesel oil, 10-15 parts of dimethyl carbonate, 10-15 parts of ether, 10-15 parts of alcohol, 2-3 parts of a preservative, 2-3 parts of a cosolvent, 2-3 parts of an antioxidant and 2-3 parts of a dispersant, wherein the ether contains 2-5 carbon atoms and the alcohol contains 5-9 carbon atoms. The preparation method comprises the following steps: mixing and stirring the methanol and the cosolvent and fully dissolving so as to obtain modified methanol; uniformly stirring and mixing the modified methanol with the light diesel oil and dimethyl carbonate so as to obtain a mixture; and sequentially adding the ether, the alcohol, the preservative, the antioxidant and the dispersant to the mixture, and uniformly mixing and stirring so as to obtain the methanol-diesel oil additive. According to the embodiment disclosed by the invention, the methanol-diesel oil additive has the effects of being environment-friendly, good in intersolubility with diesel oil, enough in power, not changing a car and capable of keeping the original structure of the car, and the like.

Description

technical field [0001] The invention relates to the field of diesel oil additives, in particular to a methanol diesel additive and a preparation method thereof. Background technique [0002] In the late 20th century, affected by the rise in international oil prices and the shortage of oil resource supply, there was a serious shortage of diesel oil at home and abroad, which brought great inconvenience to economic development and people's lives, and the burning of diesel oil caused air pollution. It is serious and endangers human health. Therefore, in order to solve the problems of diesel shortage and environmental protection, the country has issued many relevant policies to encourage the development of diesel alternative energy, and biodiesel is one of them. [0003] However, because the production of biodiesel is limited by raw materials, biodiesel cannot really become an energy substitute. For this reason, many domestic enterprises and individuals have begun to study methan...
