Zusammenfassung: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. 본 발명은 젖은 미세조류에 산을 투입하는 전처리 단계; 전처리한 상기 젖은 미세조류에 알코올 및 헥산을 투입하여 지질을 추출한 후, 추출된 상기 지질이 바이오디젤로 전환되는 추출 및 전환 단계 및 상기 바이오디젤에 산을 투입하여 정제하는 정제 단계를 포함하는 젖은 미세조류로부터 바이오디젤의 제조방법을 제공하며, 모든 공정이 한 반응기에서 일어나는 상분리법을 이용하여 설비구축비용을 절감하며, 건조 공정이 불필요한 젖은 미세조류를 활용함으로 인해 공정 운영비용을 절감하며, 또한, 정제 단계를 포함하여 바이오디젤의 순도를 향상시키는 효과가 있다.
