Catalysts for hydroconversion of heavy oils, particularly those containing Ramsbottom carbon precursors, comprise nickel or cobalt and molybdenum on porous alumina containing 1-3% silica. The catalysts have total pore volume of 0.5 to 1.5 ml/gm with at least 70% of the pore volume in pores of 40-60Å

Catalysts for hydroconversion of heavy oils, particularly those containing Ramsbottom carbon precursors, comprise nickel or cobalt and molybdenum on porous alumina containing 1-3% silica. The catalysts have total pore volume of 0.5 to 1.5 ml/gm with at least 70% of the pore volume in pores of 40-60Åpore radius and with only about 10-35% of the nickel or cobalt in acid extractable form.

A catalyst composition useful in the hydroconversion of heavy oils containing 0.5-5% of nickel or cobalt and 1.8-18% molybdenum calculated as the oxides on a porous alumina support containing 1-3% silica, characterized by having 15-30% of the nickel or cobalt in an acid extractable form and further

A catalyst composition useful in the hydroconversion of heavy oils containing 0.5-5% of nickel or cobalt and 1.8-18% molybdenum calculated as the oxides on a porous alumina support containing 1-3% silica, characterized by having 15-30% of the nickel or cobalt in an acid extractable form and further characterized by a total pore volume of 0.5-1.5 ml per gram and a pore size distribution of: at least 70% of total pore volume in pores of 40-60Åradius, not more than 0.03 ml per g. of pore volume in pores of less than 40Åradius, at least 0.05 ml per g. and not more than 0.1 ml per g. of pores greater than 60Åradius, said pore size distribution being calculated from desorption data of the nitrogen sorption isotherm.
