Embodiment 1

[0032] Take 10kg of tung tree oil and 10kg of additives, stir them and then shear and stir to obtain mixture A; take 70kg of methanol and 10kg of dimethyl ether, and mix them to obtain mixture B; then mix mixture A and mixture B, and shear Stir to obtain 100kg of biosynthetic diesel. Wherein the additive consists of the following components by weight percentage:

[0033] n-Butanol 2% to 78%;

[0034] Isobutanol 2% to 78%;

[0035] Isopropanol 2% to 78%;

[0036] Span -60 6%;

[0037] Isoamyl nitrate or amyl nitrate 4%;

[0038] Ferrocene 2%;

[0039] N, N, mono-disalicylidene propylenediamine 2%;

[0040] Benzotriazole 2%;

[0041] 2,6-di-tert-butyl-p-cresol 2%.

[0042] Compared with the national standard 0# diesel oil, the cost of the product obtained in Example 1 has decreased by about 40%, and the economic effect is remarkable. Its quality has been tested by driving, and the effects of starting, accelerating, and climbing are basically the same as those of the nat...

Embodiment 2

[0044] Take 30kg of tung tree oil and 30kg of additives, stir them and then shear and stir to obtain mixture A; take 35kg of methanol and 5kg of dimethyl ether, and mix them to obtain mixture B; then mix mixture A and mixture B, and shear Stir to obtain 100kg of biosynthetic diesel. Wherein the additive consists of the following components by weight percentage:

[0045] n-Butanol 2% to 78%;

[0046] Isobutanol 2% to 78%;

[0047] Isopropanol 2% to 78%;

[0048] Span -60 6%;

[0049] Isoamyl nitrate or amyl nitrate 4%;

[0050] Ferrocene 2%;

[0051] N,N,-Disalicylidene Propylenediamine 2%;

[0052] Benzotriazole 2%;

[0053] 2,6-di-tert-butyl-p-cresol 2%.

[0054] Compared with the national standard 0# diesel oil, the cost of the product obtained in this embodiment 2 has decreased by about 10%, and has certain economic effects, but as the country gradually liberalizes the market, its economic effects increase. Its quality has been tested by driving, and the effects of...

Abstract

The invention belongs to the fuel technical field, in particular relating to biosynthetic diesel fuel which takes animal and vegetable fat and alcohol substance and a method for preparing the same. The compositions by weight percentage of the biosynthetic diesel fuel are: 10 to 30 percent of the animal and vegetable fat, 10 to 30 percent of additives, 35 to 70 percent of methanol and 5 to 10 percent of dimethyl enther. The preparation method comprises the following steps that: various compositions of the additives are mixed so as to obtain the additives; the dimethyl enther and the methanol are mixed according to predetermined ratio so as to obtain mixture A; the additives and the animal and vegetable fat are mixed according to predetermined ratio, and cut and stirred so as to obtain mixture B; and the mixture A and the mixture B are mixed and cut and stirred so as to obtain the biosynthetic diesel fuel. The product of the biosynthetic diesel fuel greatly reduces the cost of the biodiesel because the price of the alcohol substance is much cheaper.

Description

Technical field: [0001] The invention belongs to the technical field of fuels, and specifically refers to biosynthetic diesel oil with animal and vegetable oils and alcohols as main raw materials and a preparation method thereof. Background technique: [0002] The continuous rise of international oil prices has brought economic development and energy security issues to our country. For this reason, the country attaches great importance to the research and development of petroleum substitutes. Biodiesel mainly made of animal and vegetable oils (the content of animal and vegetable oils reaches more than 90%) has the characteristics of renewable, easy to degrade, and low emission of combustion pollutants, and has been recognized as a promising alternative for internal combustion engines at home and abroad. , clean alternative energy. However, since animal and vegetable oils need to undergo esterification to make biodiesel, the process and equipment are relatively complicated,...
