A particulate catalyst composition characterized as a composite of a refractory porous inorganic support and platinum, rhenium, and iridium each in concentration of at least 0.1 wt.%, at least one metal is present in concentration of at least 0.3 wt.%, and the sum total concentration of the metals exceeds 0.9 wt.%. A process utilizing such catalysts can be operated at ultra-low pressures and ultra-low recycle rates to provide acceptable catalyst activity and C5<+> liquid yield stability. |
