    摘要： A process for removing heteroatoms from a hydrocarbonaceous feedstock using a catalyst composition comprised of: about 0.005 to 5.0 wt. % noble metal, about 0.5 to 5 wt. % of at least one Group VIII metal, and about 3 to 18 wt. % of a Group VI metal, and a refractory support, wherein the noble metal is incorporated into the refractory support by use of a precursor represented by ML.sub.2 when the noble metal is Pt or Pd, and ML.sub.3, when the noble metal is Rh or Ir, where M is the noble metal and L is a ligand selected from the dithiocarbamates, dithiophosphates, dithiophosphinates, xanthates, thioxanthates, and further wherein L has organo groups having a sufficient number of carbon atoms to render the noble metal complex soluble in oil.

    摘要： A process for selectively removing lower molecular weight naphthenic acids from an acidic crude by treating the crude with a small pore hydrotreating catalyst at temperatures of from about 200.degree. to 370.degree. C. Removing these lower molecular weight naphthenic acids reduces the corrosive nature of acidic crudes.

    摘要： A process for producing ultra clean distillate and naphtha products wherein a distillate boiling range stream which contains heteroatoms and aromatics to subjected to three stage processing. The first stage is conventional hydrotreating, wherein the resulting effluent is further hydrotreated, but with a noble metal zeolite catalyst which is typically used for hydrocracking. The effluent from this second stage, which is now substantially free of heteroatoms, is passed to a third stage. This third stage is a hydrocracking stage, the severity of which will determine if the ultimate product will be a distillate or a naphtha.
