| titleOfInvention | Method for preparing biodiesel by using high-acid value oil |
| abstract | The invention discloses a method for preparing biodiesel by using high-acid value oil. The method comprises the following steps of: 1, esterifying high-acid value oil; 2, carrying out alcoholysis on esterified oil; 3, rectifying biodiesel; and 4, recycling crude glycerine. The crude glycerine and the high-acid value oil are subjected to an esterification reaction to prepare the biodiesel, the cost of the crude glycerine is far lower than that of methanol; and meanwhile, the crude glycerine obtained through the alcoholysis reaction can also be used as a reactant in the esterification reaction of the former process, and can be recycled, and thus the cost of raw materials is saved. An alkali catalyst adopted in the esterification has the advantages of less consumption, high catalysis activity, no need of separation after reaction, and the like. Because the energy is saved, the cost of the catalyst is low and the crude glycerine obtained in the production process can be recycled, thus the processing cost of the biodiesel prepared by adopting the high-acid value oil is greatly reduced, no waste water and waste residue are emitted during the production, no three-waste emission problem is caused, and good social benefit and economic benefit are obtained. |
