Platinum Ceria WGS catalyst. Nicholas DiPreta. PGM Catalysts. Non pyrophoric - does not deactivate in presence of oxygen or water- in fact, studies have shown that 1% oxygen presence decrease deactivation high activity over a wide range of temperatures
Higher CO conversion percentage than CuZnO catalyst over wide range of temperatures (S. Swartz)
Fuelcellmaterials.com reviewed next tech’s high temperature Pt/Ce catalyst and observed little loss in CO conversion % over 300 hrs continuous run time @ 400 C.
Very little degredation over time. Little to no regeneration period needed.
As opposed to Cu-Zn-Al which reduce to about ½ co conversion % within 10 hrs (w/o regeneration)
