PREPARATION METHOD OF BIODIESEL FROM WET MICROALGAE

摘要

The present invention provides a method of producing biodiesel from wet microalgae. The method comprises: a pretreating process of inputting an acid to wet microalgae; an extracting and converting process of inputting alcohol and hexane to the pretreated wet microalgae to extract lipids and converting the extracted lipids to biodiesel; and a refining process of inputting the acid to the biodiesel to refine the same. The method has effects of: reducing facility construction costs as the method uses a phase separation method in which all processes are performed in one reactor; reducing process operating costs as the method uses wet microalgae which does not need a dry process; and enhancing the purity of the biodiesel as the method comprises the refining process.
