Process for removing arsenic with a trap catalyst before desulfurizating it

摘要

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.
