| titleOfInvention | A kind of preparation method of biodiesel |
| abstract | The invention discloses a method for preparing biodiesel, comprising: (1) in a decompressed state, glycerin and high-acid fat are reacted at 80° C. to 260° C., the acid value is reduced to below a set value, and liquid separation is performed to obtain low-acidity oil. oil and unreacted glycerin; (2) the obtained low-acid oil and fat, under the action of an alkaline catalyst, are subjected to a transesterification reaction with a low-alcohol to obtain biodiesel. Compared with the prior art, the beneficial effects of the present invention are as follows: the raw material sources of the present invention can be widely used in acidified oil, waste oil, swill oil, etc., and the raw material acid value has no special requirements and has a wide application range. There is no catalyst added in the acid reduction process, and it has the characteristics of green environmental protection and simple post-treatment. During the high temperature reaction, the water is removed in time, the reaction is continuously carried out in the positive direction, and the acid reduction is more thorough; the present invention has high transesterification yield, light product color and low soap content. |
