Beschreibung
Zusammenfassung:	The invention describes a method of treating feeds from renewable sources comprising: a hydrotreatment stage a) comprising at least two catalytic zones in which the entry stream comprising said feed mixed with at least a part of a hydrotreated liquid effluent from stage b) is introduced into the first catalytic zone at a temperature comprised between 150 and 260° C., and the effluent from the first catalytic zone is then introduced, mixed with at least a part of a hydrotreated liquid effluent from stage b) and preheated, into the following catalytic zone or zones at a temperature comprised between 260 and 320° C., a stage b) of separation of the effluent from the hydrotreatment stage a) permitting the separation of a gaseous effluent and of a hydrotreated liquid effluent of which at least a part is recycled upstream from each catalytic zone of stage a).
