Embodiment 1

[0017] A method for preparing microemulsified fuel oil by using waste animal fat, comprising the steps of:

[0018] (1) Pretreatment of chicken fat: Boil waste chicken fat at 120°C for 30 minutes, increase the temperature and control it at 135°C as the water content decreases, until deep red color appears, and keep it for 90 minutes to get the pretreatment processed chicken fat;

[0019] (2) Modification of chicken fat: take by weighing 65g of pretreated chicken fat and 60g of methyl acetate, the purity of methyl acetate is 98%; slowly stir the chicken fat at 60°C, and take 1 drop of chicken fat through a separatory funnel Add methyl acetate dropwise at a speed of / second, after the dropwise addition is completed, continue to stir for 20min to make a modified solution;

[0020] (3) Preparation of mixed solution: Weigh 10g of methanol, 2g of isobutanol and 1g of fatty alcohol polyoxyethylene ether (AEO-3); stir methanol continuously at 40°C, and mix isobutanol and fatty alcoh...

Embodiment 2

[0023] A method for preparing microemulsified fuel oil by using waste animal fat, comprising the steps of:

[0024] (1) pretreatment of chicken fat: same as step (1) operation among the embodiment 1;

[0025] (2) Modification of chicken fat: take by weighing 65g of pretreated chicken fat and 30g of methyl acetate, the purity of methyl acetate is 97%; slowly stir the chicken fat at 70°C, and add 1 drop of chicken fat through a separatory funnel Add methyl acetate dropwise at a speed of 1 / sec, after the dropwise addition is completed, continue to stir for 10min to make a modified solution;

[0026] (3) Preparation of mixed solution: Weigh 5g of methanol, 2g of n-butanol and 2g of fatty alcohol polyoxyethylene ether (AEO-3); keep stirring methanol at 50°C, and mix n-butanol and fatty alcohol polyoxyethylene ether ( AEO-3) was added into the heated methanol, and continued to stir for 5 minutes to make a mixed solution;

[0027] (4) Microemulsification: Pour the modified solution...

Embodiment 3

[0029] A method for preparing microemulsified fuel oil by using waste animal fat, comprising the steps of:

[0030] (1) pretreatment of chicken fat: same as step (1) operation among the embodiment 1;

[0031] (2) Modification of chicken fat: take by weighing 41g of pretreated chicken fat and 27g of methyl acetate, the purity of methyl acetate is 96%; slowly stir chicken fat at 55°C, and use 1 drop of chicken fat through a separatory funnel Add methyl acetate dropwise at a speed of 1 / sec, after the dropwise addition is completed, continue to stir for 15min to make a modified solution;

[0032] (3) Preparation of mixed solution: Weigh 2g of methanol, 2g of isobutanol and 0.4g of fatty alcohol polyoxyethylene ether (AEO-3); stir methanol continuously at 30°C, and mix isobutanol and fatty alcohol polyoxyethylene ether (AEO-3) was added into the heated methanol and continued to stir for 10 minutes to make a mixed solution;

Abstract

The invention belongs to the technical field of fuel oil processing, and relates to microemulsion fuel oil prepared from waste and abandoned animal grease and a processing method thereof. The microemulsion fuel oil is prepared from 40 to 70 parts of animal grease, 25 to 60 parts of methyl acetate, 1 to 10 parts of methyl alcohol, 0.2 to 10 parts of co-emulsifiers and 0.2 to 2 parts of emulsifiers,wherein the animal grease is waste and abandoned animal grease and is prepared from one or several kinds of materials in chicken oil, cow oil, sheep oil or duck oil. By using the microemulsion fuel oil, the raw materials are waste and abandoned animal grease and industrial production byproducts of methyl acetate; the sources are wide; the cost is low; the prepared fuel oil has low sulfur content,low moisture content and high calorific value, can not easily explode, can be conveniently stored and transported, can be matched with diesel oil and gasoline, and has high combustion efficiency; thepreparation method is simple, low-carbon and the environmentally-friendly; the effective utilization of resources can be realized; the added value of the animal grease can be improved.

Description

technical field [0001] The invention belongs to the technical field of fuel oil processing, and relates to a microemulsified fuel oil prepared from waste animal fats and a processing method thereof. Background technique [0002] Micro-emulsion fuel oil has processing advantages such as energy saving, less environmental pollution, and simple process equipment. Its products can be used equally with standard heavy oil, and the heat obtained is similar and the cost is low. It is currently a very promising alternative fuel. The attention of scientific researchers in various countries is a hot spot in current research. At present, the preparation of microemulsion fuel oil mainly adopts the transesterification method, and the acid or alkali catalysts commonly used in this method not only severely corrode equipment, are difficult to separate, but also have very limited direct economic benefits. Therefore, it is not conducive to the long-term production of microemulsion fuel oil. de...
