Claims
- 1. A catalyst composition consisting essentially of a porous alumina support bearing 2.5-6 wt % of a non-cobalt Group VIII metal oxide, 14.5-24 wt % of a Group VI-B oxide selected from an oxide of tungsten and molybdenum, and 0-4 wt % of a phosphorus oxide, said catalyst having a Total Surface Area of 240-320 m.sup.2 /g, Pore Volume of 0.65-0.90 cc/g, and a Pore Diameter Distribution whereby 50-62.8% of the Total Pore Volume is present as micropores of diameter 55-115 .ANG., 27.5-37% of the Total Pore Volume is present in large pores of a diameter greater than 160 .ANG., and 20-30.5% of the Total Pore Volume is present as macropores of diameter greater than 250 .ANG..
- 2. A catalyst composition as claimed in claim 1 wherein said Group VIII metal is present in amount of 2.8-3.5 wt. % as oxide.
- 3. A catalyst composition as claimed in claim 1 wherein said Group VI-B metal is present in amount of 15.0-17.0 wt. % as oxide.
- 4. A catalyst composition as claimed in claim 1 wherein said phosphorus oxide is present in amount of 1.5-3 wt. %.
- 5. A catalyst composition as claimed in claim 1 wherein said porous support is alumina.
- 6. A catalyst composition as claimed in claim 1 wherein said Group VIII metal is nickel.
- 7. A catalyst composition as claimed in claim 1 wherein said catalyst has a Total Surface Area of 240-280 m.sup.2 /g.
- 8. A catalyst composition as claimed in claim 1 wherein said catalyst has a Total Pore Volume of 0.80-0.90 cc/g.
