A process is claimed for selectively removing nitrogen from petroleum distillate feedstocks, notably lube oil distillates or lube base stocks without significant desulfurization of said petroleum distillate feedstocks, especially lube oil distillates or lube base stocks, while hydrotreating the oil to improve stability, and the like. In accordance therewith, a supported, non (metalpromoted) carbon-containing molybdenum sulfide HDN/HDS selective hydrotreating catalyst is formed from a precursor composite made by compositing a preselected quantitiy of a porous, refractory inorganic oxide with a complex salt characterized by the formula B /SUB x/ (MoO /SUB y/ S/sub 4//sub -/ /SUB y/ ) where B is (a) an alkyl substituted diammonium ion, or (2) an alkyl substituted ammonium ion or quaternary ammonium ion; x is 1 where B is an alkyl substituted diammonium ion, or 2 where B is an alkyl substituted ammonium or quaternary ammonium ion; and y is 0, or a fraction or whole number ranging up to 3. The supported, non (metal-promoted) carbon-containing molybdenum sulfide HDN/HDS selective lube oil hydrotreating catalyst is then formed from the precursor composite by heating said composite, and heat decomposing the salt of said catalyst precursor composite in the presence of hydrogen, hydrocarbon and sulfur.
