Hydroconversion process employing a catalyst with specified pore size distribution and no added silica

摘要: A process for hydroconverting a hydrocarbon feed containing components boiling above 1000 °F (538 °C), sulphur, metals and carbon residue into product decreased levels of having point greater than particularly sulphur contents in the unconverted °F+ °C+) products reduced sediment, which comprises: contacting said with hydrogen at isothermal hydroprocessing conditions presence of, as catalyst, porous alumina support ≤ 0.5 wt.% silica, no silicon being intentionally added, bearing 2.2-6 Group VIII metal oxide, 7-24 VIB oxide 0.0-2.0 phosphorus catalyst Total Surface Area 195-230 m2/g, Pore Volume (TPV) 0.82-98 cc/g, Diameter Distribution wherein 27.0-34.0 % TPV are macropores diameter > 250 A, 66.0-73.0 micropores 55-64.5 pores diameters < within ± 25 pore mode by volume 110-130 0.05 cc/g micropore 80 A.
