Abstract
The present invention relates to a process for preparing a bio-diesel, comprising the steps of, in the presence of an additional free fatty acid source, reacting a raw oil-fat with C-Cmonohydric alcohol in a reactor, and separating fatty acid esters from the reacted materials, so as to produce the bio-diesel, wherein the amount of the free fatty acid in the free fatty acid source ranges from 2-100 wt % and is higher than the amount of the free fatty acid in the raw fat-oil. The present process can increase the fatty acid ester yield and purity of raw oil-fats having a low reaction activity, and has a high adaptability to raw materials.
