Abstract
The present invention pertains to a sulfur-containing catalyst composition suitable for the hydrotreating of hydro-carbon feeds which comprises a Group VIB metal component selected from molybdenum, tungsten, and mixtures thereof, a Group V metal component selected from vanadium, niobium, tantalum, and mixtures thereof, and a Group VIII metal component selected from nickel, cobalt, iron, and mixtures thereof, the metal components (calculated as oxides) making up at least 50 wt. % of the catalyst, wherein the molar ratio between the metal components satisfies the following formula: (Group VIB+Group V):(Group VIII)=0.5-2:1. This catalyst has been found to show a high activity in sulfur removal in combination with good aromatics removal properties.
