Embodiment 1

[0027] combine figure 1 And the introduction of above-mentioned structure, we describe in detail fatty acid methyl ester biodiesel production method of the present invention, and this production method comprises the following steps:

[0028] A. Select grease and co-solvent, the percentage by weight is 60% respectively, and the co-solvent is 20%. Add the grease and co-solvent to the reaction kettle at normal temperature and pressure, and stir for 30 minutes. The internal structure of the grease is affected by the mutual dissolution of the co-solvent. destroy;

[0029] B. Add methanol to the mixture in step A, and its weight percentage is 20%. After adding, heat it while stirring. The heating temperature is 100°C. After that, the mixture in the reactor is input to the mixing In the tank, the mixing tank is equipped with a solid acid catalyst;

[0030] After C, grease, co-solvent, methyl alcohol are mixed with solid acid catalyst, backflow in the reaction kettle in the step A,...

Abstract

The invention discloses a fatty acid methyl ester biodiesel production method and a production device thereof and relates to the technical field of biodiesel. According to the method, oil, cosolvent, alcohol and solid acid catalyst are selected, and the components are heated, stirred and subjected to a circular reaction in a reaction and distillation device to prepare fatty acid methyl ester biodiesel. The method has the advantages that the components are relatively simple, a production process device is very stable, the method is a renewable energy source synthetic route, the fatty acid methyl ester biodiesel production method and the production device of the production method are used in batches and are popular with users and accepted by the users, raw material adaptability is wide, an esterification and ester exchange reaction is completed in the same solid catalyst, waste acid emission is avoided, excessive acid, solvents and reaction water can be recycled and repeatedly used, three wastes are not emitted in the production process, the side product of glycerinum can directly serve as a raw glycerinum product and be used as a glycerinum pyrolysis gas raw material, and the raw material utilization rate is 99% or above.

Description

technical field [0001] The invention relates to the technical field of biodiesel, in particular to a method for producing fatty acid methyl ester biodiesel and a production device thereof. Background technique [0002] With the depletion of petroleum resources, the increasing demand for energy and the improvement of people's awareness of environmental protection, countries around the world have accelerated the pace of developing alternative fuels, and people urgently need to find a clean, environmentally friendly and renewable energy. The cleanliness and renewability of biodiesel (fatty acid methyl ester) meet this requirement, so its development and application have received widespread attention at home and abroad. [0003] The technical definition of biodiesel refers to fatty acid monoalkyl esters obtained by transesterification of animal and vegetable oils and alcohols (such as methanol or ethanol), the most typical being fatty acid methyl esters, represented by BD100. I...
