CA 2423799

The invention relates to a process for forming a low-sulfur motor gasoline and the product made therefrom. In one embodiment, process involves separating a catalytically cracked naphtha into at least a light fraction boiling below about 165 ~F and a heavy fraction boiling above about 165 ~F. The light fraction is treated to remove sulfur by a non-hydrotreating method, and the heavy fraction is hydrotreated to remove sulfur to a level of less than about 100 ppm.

L'invention concerne un procédé destiné à produire une essence pour moteur à faible teneur en soufre, ainsi que le produit ainsi obtenu. Dans un mode de réalisation, ce procédé consiste à séparer un naphta soumis à un craquage catalytique en au moins une fraction légère bouillant à une température inférieure à environ 165 ·F et une fraction lourde bouillant à une température supérieure à environ 165 ·F. La fraction légère est traitée en vue d'extraire le soufre au moyen d'un procédé sans hydrotraitement, la fraction lourde étant soumise à un hydrotraitement en vue d'extraire le soufre jusqu'à l'obtention d'une concentration inférieure à environ 100 ppm.
