Patent

CA 2481115

The invention is directed to a process for hydroprocessing of hydrocarbon feedstock containing sulfur and/or nitrogen contaminants, said process comprising first contacting the hydrocarbon feedstock with hydrogen in the presence of at least one first group VIII metal on a first acidic support catalyst, and thereafter contacting the feedstock with hydrogen in the presence of at least one second group VIII metal catalyst on a less acidic support.

Cette invention concerne un procédé d'hydrocraquage d'une charge d'alimentation en hydrocarbure contenant des contaminants soufrés et/ou azotés, lequel procédé consiste d'abord à mettre en contact la charge d'alimentation en hydrocarbure avec de l'hydrogène en présence d'au moins un premier catalyseur métallique du groupe VIII sur un support acide, puis à mettre en contact la charge d'alimentation avec de l'hydrogène en présence d'au moins un deuxième catalyseur métallique du groupe VIII sur un support moins acide.
