Abstract
The invention is drawn to a catalyst having a substantially bimodal support phase and an active metal phase that is suitable and stable for desulfurization of high-olefin content naphtha streams with minimal octane-loss running at low hydrogen pressure. The active metal phase preferably includes cobalt, molybdenum and at least one additional metal selected from the alkali-metals group.
