Abstract:
1. A process for hydrotreating a feedstock having a relatively high nitrogen content, comprising: contacting a hydrocarbon feedstock having a nitrogen content of at least about 3000 wppm with a supported hydrotreating catalyst under first hydrotreating conditions; and contacting the hydrotreated hydrocarbon feedstock with a sulfided bulk metal catalyst under second hydrotreating conditions to produce a hydrotreated effluent, said catalyst comprising a non-noble Group VIII metal molybdate in which at least a portion, but less than all, of the molybdenum has been replaced by tungsten, the hydrotreated effluent having a sulfur content of at least about 100 wppm and a nitrogen content of at least about 100 wppm, wherein the bulk metal catalyst, prior to sulfidation, is represented by the formula: (X)
