The present invention relates to a process for the selective conversion of hydrocarbon feed having a Conradson Carbon Residue content of 0 to 6 wt%, based on the hydrocarbon feed (8). The hydrocarbon feed (18) is treated in a two-step pro-cess. The first is thermal conversion (12) and the second is catalytic cracking (26) of the products of the thermal conversion (12). The present invention results in a process for increasing the distillate production (16) from a hydrocarbon feedstream for a fluid catalytic cracking unit. The resulting product slate from the present invention can be further varied by changing the conditions in the thermal (12) and catalytic cracking (26) steps as well as by changing the catalyst in the cracking step (26).

La présente invention porte sur un procédé pour la conversion sélective d'une charge d'alimentation hydrocarbonée dont la teneur en résidu Conradson est de 0 à 6 % en poids, par rapport à la charge d'alimentation hydrocarbonée. La charge d'alimentation hydrocarbonée est traitée dans un procédé en deux étapes. La première étape est une conversion thermique et la seconde étape est un craquage catalytique des produits de la conversion thermique. La présente invention concerne un procédé permettant l'augmentation de la production de distillat à partir d'un courant d'alimentation hydrocarboné pour une unité de craquage catalytique fluide. Les spécifications du produit résultant de la présente invention peuvent en outre être modifiées en faisant varier les conditions dans les étapes thermiques et de craquage catalytique ainsi qu'en faisant varier le catalyseur dans l'étape de craquage.
