<p>Treating charges obtained from renewable sources comprises: (a) hydrotreating comprising at least two catalytic areas in which the incoming stream comprises the charge mixed with at least a part of a hydrotreated liquid effluent obtained from step (b) and a hydrogen-rich gas is introduced into the first catalytic area at a temperature of 150-260[deg] C; and (b) separating the effluent obtained from the step (a) of hydrotreatment allowing the separation of a gaseous effluent and a hydrotreated liquid effluent of which at least a part is recycled at the top of each catalytic area of step (a). Treating charges obtained from renewable sources comprises: (a) hydrotreating comprising at least two catalytic areas in which the incoming stream comprises the charge mixed with at least a part of a hydrotreated liquid effluent obtained from step (b) and a hydrogen-rich gas, and is introduced into the first catalytic area at a temperature of 150-260[deg] C, in which the effluent obtained from the first catalytic area is then introduced, mixed with at least a part of a hydrotreated liquid effluent obtained from step (b) and preheated in the following catalytic areas at a temperature of 260-320[deg] C; and (b) separating the effluent obtained from the step (a) of hydrotreatment allowing the separation of a gaseous effluent and a hydrotreated liquid effluent of which at least a part is recycled at the top of each catalytic area of step (a), the process implementing in at least the catalytic areas following the first of step (a) of hydrotreatment, where bulk catalyst or supported catalyst comprises an active phase constituted of at least one element of group VIB, and the element of group VIB is molybdenum.</p> |
