Patent ID: 8580108

Claim:
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comprising a non-noble Group VIII metal molybdate in which at least a portion, but less than all, of the molybdenum has been replaced by tungsten, the hydrotreated effluent having a sulfur content of at least about 100 wppm and a nitrogen content of at least about 100 wppm, wherein the bulk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) b (Mo) c (W) d O z , wherein X is a non-noble Group VIII metal, the molar ratio of b:(c+d) is from about 0.5:1 to about 3:1, the molar ratio of c:d is greater than about 0.01:1, and z=[2b+6(c+d)]/2.
