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.
