Background
With the continuous development of social economy and science and technology, the energy crisis and environmental pollution problem become two major problems threatening the sustainable development of the earth, petroleum is called as industrial 'blood', but is an increasingly exhausted energy source, and the application of a plurality of petroleum products such as diesel oil and gasoline can bring serious pollution to the environment.
Biodiesel has been proved to be a pollution-free renewable energy source, can completely replace petroleum diesel, and also has the advantages of higher cetane number, high flash point, good antiknock performance, convenient storage and transportation and the like. The biodiesel is incorporated into a large-scale popularized and applied biological energy source by European and American countries. At present, there are many methods for producing biodiesel in China, including various methods such as a pyrolysis method, a micro-emulsification method, a dilution method, an ester exchange method, animal enzymes and the like, but all the methods generally have 1) a lot of applied chemical materials; 2) the processing and manufacturing process is complex, and high-temperature and high-pressure distillation and other links are required; 3) the method comprises the following steps of a plurality of steps, wherein most of the steps need acidification, esterification and the like; 4) the environment is polluted by clay and the like in some cases; and 5) high cost.
The invention takes the waste swill-cooked dirty oil of the catering industry as the raw material, changes the swill-cooked dirty oil into valuable through simple process and material, solves the problem of treatment of the waste swill-cooked dirty oil and the problem of energy, and has great economic and social benefits.
Disclosure of Invention
The invention relates to a method for preparing biodiesel by using illegal cooking oil in catering industry as a raw material.
The invention is a method for preparing biodiesel by using animal and vegetable oil, which has simple process and does not need complex conditions such as high temperature and high pressure.
The method for preparing the biodiesel provided by the invention comprises the following steps: mixing the illegal cooking oil with impurities and water removed and methanol according to a volume ratio of 100: 21-24 g of illegal cooking oil and sodium hydroxide (or 12-16 g of illegal cooking oil and potassium hydroxide) per liter, placing the three materials into a container at the temperature of 61-65 ℃ under normal pressure, stirring for 30 minutes to 1 hour, standing for 4-6 hours, naturally settling and layering, and separating out glycerin at the lower layer to obtain the biodiesel.
The invention has the advantages that: the process is simple, no high temperature, high pressure and other environment is needed, the used material is less, no pollution is caused, and the glycerin obtained by the reaction can be recycled as feed raw material or other medicine and cosmetic raw materials.
Detailed Description

2. 10-14 g of hogwash oil sodium hydroxide per liter (or 12-16 g of hogwash oil and potassium hydroxide per liter) according to the mixture ratio;
3. heating the illegal cooking oil to the range of 61-65 ℃;
4. adding the sodium hydroxide (or potassium hydroxide) into methanol, and stirring to fully dissolve;
5. adding methanol dissolved with sodium hydroxide (or potassium hydroxide) into illegal cooking oil at the temperature of 61-65 ℃, and stirring for 30 minutes to 1 hour;
6. standing the solution stirred in the step 5 for 4 to 6 hours to naturally precipitate and stratify the solution;
7. separating out the glycerin in the lower layer to obtain the biodiesel.
The following examples are presented to further illustrate the embodiments of the present invention, but are not intended to limit the scope of the invention.
Example 1
Taking 1 liter of the processed illegal cooking oil without impurities and water, and heating the illegal cooking oil to the range of 61-65 ℃; 210 ml of methanol is taken and put into a cup; 10 g of sodium hydroxide was taken and put into methanol, and stirred to be sufficiently dissolved. And when the temperature of the illegal cooking oil reaches the range of 61-65 ℃ and the sodium hydroxide is completely dissolved in the methanol, pouring the methanol in which the sodium hydroxide is dissolved into the illegal cooking oil, stirring for 1 hour, standing for 4-6 hours, and separating out the glycerin at the bottom layer to obtain the biodiesel.
Example 2
Taking 1 liter of the processed illegal cooking oil without impurities and water, and heating the illegal cooking oil to the range of 61-65 ℃; taking 230 ml of methanol, and putting the methanol into a measuring cup; 13 g of sodium hydroxide was taken and put into methanol, and stirred to be sufficiently dissolved. And when the temperature of the illegal cooking oil reaches the range of 61-65 ℃ and the sodium hydroxide is completely dissolved in the methanol, pouring the methanol in which the sodium hydroxide is dissolved into the illegal cooking oil, stirring for 1 hour, standing for 4-6 hours, and separating out the glycerin at the bottom layer to obtain the biodiesel.
The basic description of the invention is given above, and any modification, equivalent transformation or improvement made according to the principle and technical scheme of the invention shall be covered within the protection scope of the invention.
