Abstract
The invention relates to a bulk metal hydrotreating catalyst, suitable for the production of low sulfur diesel fuels, said bulk metal hydrotreating catalyst being in the oxide state and having a composition of MoxCoyNbz, excluding the oxygen, wherein x, y, and z represent about 0.1 to about 2 moles of Mo, about 0.5 to about 2 moles of Co, and about 0.1 to about 2 moles Nb and wherein Nb is present in amounts from about 2 to about 45 wt. %, Mo is present in amounts from about 1 to about 50 wt. %, and Co is present in amounts from about 10 to about 45 wt. %.
Claims16
A bulk metal diesel-boiling-range hydrotreating catalyst in the oxide state consisting essentially of MoxCoyNbz, excluding the oxygen, wherein x, y, and z represent about 0.1 to about 2 moles of Mo, about 0.5 to about 2 moles of Co, and about 0.1 to about 2 moles of Nb, and wherein Nb is present in amounts from about 2 to about 45 wt. %, Mo is present in amounts from about 1 to about 50 wt. %, and Co is present in amounts from about 10 to about 45 wt. %, calculated as oxides, based on the total weight of the bulk metal hydrotreating catalyst.
