A catalyst composition is provided which comprises a magnesium aluminate spinel having a surface area of greater than about 50 m2/g, a total pore volume of greater than about 0.475 cc/g from about 50 to about 70 percent of the total pore volume in pores of diameter of from about 50 Angstroms to about 150 Angstroms, greater than about 30 percent of the total pore volume in pores of diameter of from about 80 Angstroms to about 150 Angstroms and from about 5 to about 20 percent of the total pore volume in pores of diameter of greater than 300 Angstroms, said magnesium aluminate spinel having deposited thereon from about 1 to about 5 weight percent cobalt oxide and from about 8 to about 20 weight percent molybdenum oxide. |
