Abstract: Provided is a hydro-regeneration catalyst system, comprising: (a) a first graded bed comprising a guard bed material; and (b) a second graded bed, fluidly connected to the first graded bed, comprising a noble metal catalyst on a support having mesopores and macropores; wherein the noble metal catalyst has an average pore diameter of 20 to 1,000 nm (0.02 to 1 μm), a total pore volume of greater than 0.80 cc/g, and a macropore volume of 0.10 to 0.50 cc/g. Also provided is a guard bed system, comprising: (a) a first guard bed comprising a first adsorbent having 10 μm or larger pores with an average pore diameter of 100 to 1,000 μm; and (b) a second guard bed fluidly connected to the first guard bed, comprising a second adsorbent material having mesopores and macropores with a second average pore diameter of 20 to 1,000 nm.

Abstract: A catalyst system has been designed that disrupts the sedimentation process. The catalyst system achieves this by saturating key feed components before the feed components are stripped into their incompatible aromatic cores. The efficacy of this disruptive catalyst system is particularly evident in a hydrocracker configuration that runs in two-stage-recycle operation. The catalyst is a self-supported multi-metallic catalyst prepared from a precursor in the hydroxide form, and the catalyst must be toward the top level of the second stage of the two-stage system.
