Transcript of Nicholas DiPreta. Non pyrophoric- does not deactivate in presence of oxygen or water- in fact,...
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
excellent stability at high temperatures Resistance to sulfur containing gases to
about 10 ppm H₂S
PGM Catalysts
Higher CO conversion percentage than CuZnO catalyst over wide range of temperatures (S. Swartz)
Temperature Range
Life Time
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.
Life Time
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) [Kim et al. 2005]
