Method for the production of renewable kerosene or 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 step a) of hydrotreating said raw material, a step b) of separating the effluent obtained from step a) into a light fraction and a liquid hydrocarbon effluent, a step c) involving the liquid hydrocarbon effluent obtained from step c), said step c) being characterized by the use of 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 structure code MTW and zeolite IZM-2, and at least one binder, and a step d) of separating the effluent obtained in step c), which allows the separation of a gaseous fraction and a liquid hydrocarbon effluent, and a step e) of stabilizing the hydrocarbon effluent obtained in step d).in order to separate three hydrocarbon fractions: a light gaseous fraction, a naphtha fraction and, alternatively, a gas oil fraction or a kerosene fraction, without recycling, in the hydrotreatment stage a) and / or the hydroconversion stage c), from all or some of the effluents obtained from the hydroconversion stage c), from the effluents from the separation stage d) and / or from the effluents from the stabilization stage e).
