IMPROVED SELECTIVE CRACKED NAPHTHA DESULFURIZATION USING ARSENIC TRAP CATALYSTS

Arsenic trap catalyst can be used as part of a process for selective hydrodesulfurization of a naphtha feed. Use of an arsenic trap catalyst can allow for use of a reduced amount of hydrodesulfurization catalyst. This can allow for an increased start of run temperature, which can enhance the octane...

Summary:Arsenic trap catalyst can be used as part of a process for selective hydrodesulfurization of a naphtha feed. Use of an arsenic trap catalyst can allow for use of a reduced amount of hydrodesulfurization catalyst. This can allow for an increased start of run temperature, which can enhance the octane number for the resulting desulfurized naphtha product. Selon l'invention, un catalyseur de piégeage d'arsenic peut être utilisé comme partie d'un procédé d'hydrodésulfuration sélective d'une charge naphta. L'utilisation d'un catalyseur de piégeage d'arsenic permet d'utiliser une dose réduite de catalyseur d'hydrodésulfuration, ce qui autorise un début augmenté de la température d'exécution, ce qui peut renforcer le nombre d'octanes pour le produit naphta désulfuré qui en résulte.
