<p>A method for making a hydrotreating catalyst wherein the catalyst is prepared by mixing a peptized hydrated supporting oxide with a hydrated Group IVB metal oxide gel promoter. The Group VIII metals are mixed in with the Group IVB metal oxide gel promoter. A solution containing a soluble Group VIB metal and a basic compound is added. The catalyst is used for hydrodenitrogenation and Ramsbottom Carbon Residue reduction of a hydrocarbon feedstock.</p> |
