Abstract[English]
The present invention aims to provide a method for producing kerosene from a paraffinic feedstock produced by Fischer-Tropsch synthesis, the method comprising at least one hydrocracking step and at least one hydroisomerization step arranged in series, the operating conditions and the catalysts used in the steps being specifically selected to selectively produce a kerosene fraction while minimizing the production of light fractions such as C1-C4 light gases and naphtha, by virtue of specific management of the recycle gases, and also making it possible to carry out hydroisomerization step e) and/or hydrocracking step c) at a pressure lower than hydrotreating step a).[French]
Un objectif de la présente invention est donc de fournir un procédé de production de kérosène à partir d'une charge paraffinique produite par synthèse Fischer-Tropsch comprenant au moins une étape d'hydrocraquage et au moins une étape d'hydroisomérisation disposées en série, les conditions opératoires et les catalyseurs mis en œuvre dans lesdites étapes étant choisies de manière bien spécifique, pour produire sélectivement une coupe kérosène, tout en minimisant la production de coupes légères telles que les gaz légers en C1-C4, naphta grâce à une gestion spécifiques des gaz de recycle et permettant également d'opérer l'étape e) d'hydroisomérisation et/ou l'étape c) d'hydrocraquage à un niveau de pression inférieur à l'étape a) d'hydrotraitement.
