| titleOfInvention | Method for extracting and purifying microalgae biodiesel |
| abstract | The invention relates to a method for extracting and purifying microalgae biodiesel. The method comprises the following steps: crushing microalgae, namely, introducing an algae liquid into a crushing tank, crushing microalgae with ultrasonic waves, feeding into a settling pond, performing natural precipitation to form an upper layer and a lower layer, and sucking algae slurry of the lower layer into a reaction tank, wherein the upper layer is water, and the lower layer is algae slurry; performing in-situ extraction, namely, adding a reaction agent and an extraction agent into the reaction tank with the algae slurry, heating till the temperature is 60-70 DEG C, and stirring all the time; performing separation purification, wherein n-hexane is adopted as an extraction agent; the volume ratio of the reaction agent to the extraction agent is 1:1; the volume ratio of the reaction agent to the algae slurry is (1-2):1; and the extraction agent needs to be replaced once every 4-6 hours; and after extraction is completed, sucking the upper liquid obtained after extraction into a collecting tank, stirring while heating, and evaporating the extraction agent into a condenser, thereby obtaining the biodiesel which is left in the reaction tank. The method has the advantages that material consumption is reduced, the steps are simple, the operation is simple and convenient, and the yield can be approximate to 100%. |
