Problems solved by technology

[0004] The cold filter point of biodiesel is around 0°C, crystallization and gelation at low temperature limit the application of biodiesel under low temperature flow conditions
The method of using diesel oil additives in the prior art can improve the low-temperature fluidity of diesel oil, promote the combustion of diesel oil or improve the anti-explosion property of diesel oil to a certain extent, but the function is single and can only improve a certain performance of diesel oil. One performance will reduce other performances and indicators at the same time, lack of synergy between components

Embodiment 1

[0017] Weigh the following components by weight: 10 parts of lauryl methacrylate, 10 parts of cyclohexylamine, 7 parts of toluene, 2 parts of isooctyl nitrate, 5 parts of polyisobutylamine, 1 part of diphthalate Ethyl ester, 1 part of phenyl propargyl ether, 5 parts of benzotriazole, 1 part of isooctyl alcohol, mix the above components together and stir for 30-35 minutes; then heat at 40°C-60°C, at 0.5- Stir at 1.0 MP for 15-20 minutes, stand still for 20-30 hours, filter, remove precipitates, and obtain the biodiesel additive.

Embodiment 2

[0019] Weigh the following components by weight: 25 parts of lauryl methacrylate, 20 parts of cyclohexylamine, 16 parts of toluene, 15 parts of isooctyl nitrate, 15 parts of polyisobutylamine, 7 parts of diphthalate Ethyl ester, 10 parts of phenyl propargyl ether, 15 parts of benzotriazole, 8 parts of isooctyl alcohol, mix the above components together and stir for 30-35 minutes; then heat at 40°C-60°C, at 0.5- Stir at 1.0 MP for 15-20 minutes, stand still for 20-30 hours, filter, remove precipitates, and obtain the biodiesel additive.

Embodiment 3

[0021] Weigh the following components by weight: 18 parts of lauryl methacrylate, 15 parts of cyclohexylamine, 10 parts of toluene, 6 parts of isooctyl nitrate, 9 parts of polyisobutylamine, 4 parts of diethyl phthalate Esters, 6 parts of phenyl propargyl ether, 12 parts of benzotriazole, 6 parts of isooctyl alcohol, mix the above components together and stir for 30-35 minutes; then heat at 40°C-60°C at 0.5-1.0 Stir under MP for 15-20 minutes, stand still for 20-30 hours, filter, remove precipitates, and obtain the biodiesel additive.

[0022] Adding a small amount of the biodiesel additive provided by the invention to diesel can reduce the solidification temperature of biodiesel by many degrees, maintain good low-temperature fluidity of biodiesel, and facilitate the storage, transportation and use of diesel. The biodiesel additive provided by the invention contains both non-polar groups and polar groups. When the added diesel oil cools down, the non-polar side chain alkanes ...

Abstract

The invention relates to a biodiesel additive and a preparation method of the biodiesel additive. The biodiesel additive comprises the following components by weight: 10-25 parts of dodecyl methacrylate, 10-20 parts of cyclohexylamine, 7-16 parts of methylbenzene, 2-15 parts of isooctyl nitrate, 5-15 parts of polyisobutylene amine, 1-7 parts of diethyl phthalate, 1-10 parts of phenyl propargyl ether, 5-15 parts of benzotriazole, and 1-8 parts of isooctyl alcohol. The provided biodiesel additive has an excellent effect of reducing the cold filter plugging point, does not cause the problem of reversion of the cold filter plugging point, does not affect the effects of other diesel additives, has an excellent stable dispersing power, and is excellent in oil solubility.

Description

technical field [0001] The invention belongs to the technical field of resources and environment, and in particular relates to a biodiesel additive and a preparation method thereof. Background technique [0002] Biodiesel is an environmentally friendly biofuel produced from unprocessed or used vegetable oils and animal fats through different chemical reactions. This biofuel can be used like diesel. The most common method of producing biodiesel is transesterification. Fatty acid esters are formed by reacting triglycerides, which are the main components in vegetable oils and fats, with alcohols (usually methanol) in the presence of catalysts. The physical and chemical properties of fatty acid esters are very similar to diesel or even better. [0003] Biodiesel is a clean and renewable energy source. It is mainly a liquid fuel made from oil crops such as soybeans and rapeseeds, oil-bearing forest fruits such as oil palm and pistachio, engineering microalgae and other oil-bea...
