Abstract:
1. A process for producing low sulfur diesel products from a diesel boiling range feedstream comprising: a) contacting a diesel boiling range feedstream containing aromatics, nitrogen and organically bound sulfur contaminants in a reaction stage with a bulk metal hydrotreating catalyst having metals consisting of Nb, Mo, and at least one metal selected from Group VIII metals in the presence of hydrogen-containing treat gas thereby producing a reaction product comprising at least a vapor product and a liquid diesel boiling range product, wherein said diesel boiling range feedstream is contacted with said catalyst under effective hydrotreating conditions, wherein said bulk metal hydrotreating catalyst comprises about 15 to about 20 wt. % Nb, about 15 to about 30 wt. % Mo, and about 30 to about 40 wt. % of said at least one Group VIII metal selected from Co, Ni, Rh, Pt, Pd, Ir, and mixtures thereof.
