Abstract: Processes for desulfurizing a fluid catalytic cracker (FCC) naphtha feedstock, straight run naphtha feedstocks and combinations thereof are provided herein. Naphtha boiling range feed is passed over a silicon trap prior to being hydrodesulfurized in an olefin-retentive, catalytic naphtha hydrodesulfurization process. Processes for removing silicon from FCC naphtha feedstock, straight run naphtha feedstock and combinations thereof are also provided herein.
