An embodiment of the present invention provides a method for producing bio-diesel, the method comprising the steps of: mixing animal lipids, a solvent, and a catalyst in a reactor to cause an esterification reaction, and producing a crude bio-diesel; removing the solvent from the crude bio-diesel through first vacuum distillation; removing glycerol from the crude bio-diesel through layer separation; removing the catalyst from the crude bio-diesel by washing with water; and removing a sulfur component from the crude bio-diesel from which the solvent, the glycerol, and the catalyst have been removed, through second vacuum distillation, and producing a high-purity bio-diesel. Un mode de réalisation de la présente invention concerne un procédé de production de biodiesel, le procédé comprenant les étapes consistant à : mélanger des lipides d'origine animale, un solvant et un catalyseur dans un réacteur pour provoquer une réaction d'estérification, et produire un biocarburant brut ; éliminer le solvant du biodiesel brut par une première distillation sous vide ; éliminer le glycérol du biodiesel brut par séparation de couches ; éliminer le catalyseur du biodiesel brut par lavage à l'eau ; et éliminer un composant soufré du biodiesel brut dont le solvant, le glycérol et le catalyseur ont été éliminés, par une seconde distillation sous vide, et produire un biodiesel de haute pureté. 본 발명의 일 실시예는, 반응기 내에서 동물성 지질, 용매, 및 촉매를 혼합하여 에스테르화 반응을 수행하고, 크루드 바이오디젤을 생성하는 단계; 상기 크루드 바이오디젤에서 1차 감압증류를 통해 상기 용매를 제거하는 단계; 상기 크루드 바이오디젤에서 층분리를 통해 글리세롤을 제거하는 단계; 상기 크루드 바이오디젤에서 수세를 통해 상기 촉매를 제거하는 단계; 및 상기 용매, 상기 글리세롤, 및 상기 촉매가 제거된 상기 크루드 바이오디젤에서 2차 감압증류를 통해 황 성분을 제거하고 고순도 바이오디젤을 생성하는 단계를 포함하는, 바이오디젤 제조방법을 제공할 수 있다.
