Abstract
A process for hydrotreatment of a feed from renewable sources such as vegetable oils for the production of paraffinic hydrocarbons comprising pre-treatment by crystallisation and/or precipitation allowing the elimination of insoluble inorganic impurities under hydrotreatment conditions. The flow of the total feed is divided up into a certain number of different, part flows equal to the number of catalytic zones in the reactor, and the different part flows are injected in the successive catalytic zones in increasing proportions to produce an effluent containing paraffinic hydrocarbons.
