Abstract
Disclosed is a catalyst including metal phosphide for preparation of biodiesel, and a method of preparing biodiesel from feedstock comprising vegetable oil through hydrotreating using the catalyst. When the catalyst including metal phosphide is used as a catalyst for preparation of biodiesel, preparation activity of hydrotreated biodiesel is high even without continuous supply of sulfiding agent, and hydrotreating and isomerization reactions occur at the same time, thus obtaining high-quality hydrotreated biodiesel having a low pour point.
