Abstract:
1. A catalyst composition comprising a molybdenum component in an amount of less than 11 wt.%, with the wt.% being based on the total weight of said catalyst composition and assuming said molybdenum component is in the oxide form (MoO 3 ) regardless of its actual form, and a nickel component present in an amount such that said catalyst composition has a weight ratio of said nickel component-to-said molybdenum component exceeding 0.25, with said weight ratio being computed assuming said nickel component and said molybdenum component are each in the oxide form regardless of their actual forms; wherein the catalyst composition is prepared by mixing alumina powder, a nickel compound, and a molybdenum compound to provide a co-mulled mixture, comprising said nickel compound, said molybdenum compound and alumina; forming an agglomerate of said co-mulled mixture; and calcining said agglomerate in air without added steam under calcination conditions that include a calcination temperature exceeding 1150° F. to thereby provide said catalyst composition; wherein said mixing step further includes mixing calcined catalyst fines with said alumina powder, said nickel compound, and said molybdenum compound to thereby form said co-mulled mixture, wherein said co-mulled mixture includes an amount of said calcined catalyst fines so as to provide for a desired macroporosity of said catalyst composition; and wherein said catalyst composition has a total surface area in the range of from 240 m 2 /g to 360 m 2 /g; a total pore volume of at least 0.65 cc/g; and a pore size distribution such that at least 10% of the total pore volume is present in macropores of diameter greater than about 250 Å, from 19.5% to 37% of the total pore volume of said catalyst composition is present as pores having diameters of greater at least 160 Å; from 50% to 75% of the total pore volume of said catalyst composition is present as pores of diameter in the range of from 55 Åto 115 Å; from 20% to 30.5% of the total pore volume of said catalyst composition is present as pores in the range of from 250 Åto 500 Å; more than 20% of the total pore volume of said catalyst composition is present in pores of diameter in the range of from 50 Åto 100 Å; and less than 30% of the total pore volume of said catalyst composition is present in pores of diameter in the range of from 100 Åto 200 Å.
