A process is provided for selectively producing diesel fuel with increased cetane number from a hydrocarbon feedstock. The process includes contacting the feedstock with a catalyst which has a large pore crystalline molecular sieve material component having a faujasite structure and alpha acidity of less than 1, preferably 0.3 or less. The catalyst also contains a dispersed Group VIII noble metal component which catalyzes the hydrogenation/hydrocracking of the aromatic and naphthenic species in the feedstock.
L'invention concerne un procédé permettant de produire sélectivement un gazole à indice de cétane amélioré à partir d'une charge d'hydrocarbures. Ledit procédé consiste à placer la charge au contact d'un catalyseur constitué d'un composant tamis moléculaire cristallin à larges pores ayant la structure de la faujasite et une acidité alpha inférieure à 1, de préférence inférieure ou égale à 0,3. Le catalyseur renferme également un composant dispersé constitué d'un métal noble du groupe VIII permettant de catalyser l'hydrogénation/hydrocraquage des espèces aromatiques et naphténiques de la charge.
