Abstract
The invention relates to a method of treating feedstocks from renewable sources without intermediate gas-liquid separation in order to produce diesel fuel bases of excellent quality. The feedstocks used can be raw vegetable oils or such oils that have been previously subjected to a prerefining stage, animal fats, or mixtures of such feedstocks. The invention relates to a method allowing high diesel fuel base yields to be obtained from such feedstocks.
