Problems solved by technology

The preparation of biodiesel by this transesterification method belongs to the chemical preparation method, which has the following disadvantages: the process is complicated, the alcohol must be excessive, and the corresponding alcohol recovery device must be installed in the follow-up process, the energy consumption is high, and the equipment investment is large; the esterification product is difficult to recycle. The recycling cost is high; the waste lye is discharged during the production process, which will cause secondary pollution to the environment and other disadvantages

Embodiment 1

[0024] The diesel reverse micelle system consists of 2.5g rhamnolipid, 45.0ml diesel, 1.5g n-octanol and 1.2mL water.

[0025] The preparation method of the diesel reverse micelle system is as follows: weigh 2.5g rhamnolipid and add it to 45.0mL diesel oil, sonicate until the rhamnolipid is completely dissolved and the solution is clear, then slowly add Add 1.5g of n-octanol, then add 1.2mL of ultrapure water, shake well, let it stand for a while, the solution gradually becomes clear, the excess water is separated in the lower layer, and the diesel reverse micelle system is obtained.

Embodiment 2

[0027] Biodiesel, consisting of 42.5ml diesel reverse micellar system, 7.5ml castor oil.

[0028] The preparation method of biodiesel is as follows: take 42.5mL of the diesel reverse micelle system prepared in Example 1, slowly add 7.5mL of castor oil into it, shake well, place it in a constant temperature water bath for 30min, control the temperature at 40°C, shake The speed was controlled at 180rpm. After shaking, the solution was in a turbid state, and then centrifuged at 6000rpm for 6 minutes to accelerate the stratification. After centrifugation, the solution was divided into two layers, the lower layer was the impurity layer, and the upper layer was biodiesel.

[0029] The biodiesel obtained in this example has a dynamic viscosity of 7.89 mpa s as measured by a SNB-2 digital viscometer under the Jingtian brand at 30°C, which is slightly higher than the viscosity of diesel oil (diesel viscosity ranges from 3 to 8mpa s), the corrosion resistance measured by the GB / T 5096 c...

Embodiment 3

[0031] The diesel reverse micelle system consists of 1.5g rhamnolipid, 45.0ml diesel, 0.9g n-octanol and 1.2mL water.

[0032] The preparation method is as follows: weigh 1.5g rhamnolipid and add it to 45.0mL diesel oil, sonicate until the rhamnolipid is completely dissolved and the solution is clear, then slowly add 0.9g n-octanol to the rhamnolipid-diesel solution, Then add 1.2mL of ultrapure water, stir, and let it stand for a while, the solution will gradually become clear, the excess water will be separated in the lower layer, and the diesel reverse micelle system will be obtained.

Abstract

The invention relates to a diesel reverse micelle system, a preparation method, an application, biodiesel and a preparation method thereof. The diesel reverse micelle system is composed of rhamnolipid, diesel oil, a cosurfactant and water, with diesel oil as a solvent, rat The concentration of rhamnolipid is 30-75g / L, the concentration of co-surfactant is 15-60g / L, and the concentration of water is 24-30mg / L. The preparation method is to dissolve rhamnolipid in diesel oil, and then add co-surfactant The active agent and excess water are mixed, left standing, and separated to obtain a diesel reverse micelle system. The biodiesel is composed of a volume ratio of 80-95% diesel reverse micelle system and 5-20% castor oil. The preparation method is to Castor oil is added to the diesel reverse micelles system, heat-preserved and oscillated, centrifuged, and separated to obtain biodiesel. The present invention uses the diesel reverse micelles system to mix castor oil to prepare biodiesel, without changing the chemical structure of castor oil, and there is no secondary process in the preparation process. Pollution, simple process.

Description

technical field [0001] The invention relates to a reverse micelle system and biodiesel, in particular to a diesel reverse micelle system, a preparation method, an application, biodiesel and a preparation method. Background technique [0002] At present, my country's dependence on foreign oil has exceeded 50%, exceeding the national energy security warning line. With the gradual improvement of people's living standards, my country's demand for oil is increasing. Not only that, the environmental conditions caused by automobile exhaust are deteriorating day by day. Therefore, it is more and more urgent to find a renewable clean energy source, among which biodiesel and Renewability and low emissions have attracted the attention of countries all over the world. [0003] Traditional biodiesel uses oil crops, animal fats, catering waste oils, wild oil plants and aquatic vegetable oils such as engineering microalgae as raw materials, and is made into a clean and renewable diesel fue...
