Beschreibung
Zusammenfassung:	Systems and methods are provided for producing an improved product slate during hydrocracking of a feedstock that results in production of naphtha and distillate fuels. The methods can include use of stacked beds and/or sequential reactors so that a feedstock is exposed to suitable catalysts under hydrocracking conditions and aromatic saturation conditions. The catalyst for performing the aromatic saturation process can be a catalyst including a Group VIII noble metal, such as Pt, Pd, or a combination thereof, while the hydrocracking catalyst can include Group VIB and Group VIII non-noble metals. L'invention concerne des systèmes et des procédés de production d'un produit aux spécifications améliorées pendant l'hydrocraquage d'une charge d'alimentation donnant de l'essence et du gazole. Ces procédés peuvent comprendre l'utilisation de lits empilés et/ou de réacteurs séquentiels de sorte que la charge d'alimentation est exposée à des catalyseurs appropriés dans des conditions d'hydrocraquage et de saturation aromatique. Le catalyseur utilisé pour le processus de saturation aromatique peut être un catalyseur comprenant un métal noble du groupe VIII, tel que Pt, Pd ou une combinaison de ceux-ci, tandis que le catalyseur d'hydrocraquage peut comprendre des métaux non nobles des groupes VIB et VIII.
