Abstract: The present invention provides a catalyst composition comprising: a) an inorganic, porous, mesoporous binder material, wherein the binder material comprises at least silica and alumina; b) a supported material, wherein the supported material has a framework comprising silica and alumina in a weight ratio of silica to alumina of about 10:1 to about 50:1, and has an average pore diameter of about 15 to about 40 Å; and c) a hydrogenation-dehydrogenation component, which is selected from the Group VIII noble metals and mixtures thereof; wherein the catalyst composition has a collidine uptake at 200° C. of greater than 150 μmol/g, 200 μmol/g, or 300 μmol/g, or 350 μmol/g. The catalyst is used in the hydroprocessing of a hydrocarbon feedstream to reduce an aromatic content of the hydrocarbon feedstream.
