Method for the co-production of renewable kerosene and diesel by two-stage hydroprocessing using a specific catalyst for the hydroconversion stage without recycling

Abstract

The present invention describes a process for treating a raw material derived from a renewable source, comprising a hydrotreatment step (a), a step (b) of separating at least a portion of the effluent obtained from step (a) into at least a light fraction and at least a hydrocarbon effluent, a step (c) of hydroconverting the hydrocarbon effluent obtained from step (c) using at least one specific bifunctional catalyst comprising at least one noble metal of Group VIII selected from platinum and palladium and a support comprising at least one zeolite selected from zeolites with structural code MTW and zeolite IZM-2, alone or as a mixture, and at least one binder, and a step (d) of separating the effluent obtained from step (c), which allows the separation of at least a gaseous fraction and at least a liquid hydrocarbon effluent.a stage e) of fractionating the hydrocarbon effluent obtained from stage d) into at least a diesel cut and a kerosene cut, without recycling, in the hydrotreating stage a) and / or the hydroconversion stage c), of all or some of the effluents obtained from the hydroconversion stage c), of the effluents from the separation stage d) and / or of the effluents from the fractionation stage e).
