Abstract
A method of treating feedstocks from renewable sources in order to produce diesel fuel bases of excellent quality. The feedstocks used can be, for example, raw vegetable oils or such oils that have been previously subjected to a prerefining stage, animal fats, or mixtures of such feedstocks. The method includes fixed bed catalytic hydrotreatment, followed by fixed bed hydroisomerization with a catalyst based on monodimensional 10 MR zeolite and at least one metal from group VIII and/or VIB.
