Abstract
Naphtha is selectively hydrodesulfurized in the presence of a sulfided, treated catalyst comprising at least a Group VIB metal catalytic component, to produce sulfur-reduced naphtha with reduced olefin loss due to saturation. The catalyst is treated with hydrogen, a selectively deactivating agent which deactivates its hydrogenation activity, and a protective agent which preserves its hydrodesulfurization activity during the treatment.
