Reaction mechanisms for hydrogen

1) Surface reactions: Catalytic combustion of hydrogen on palladium

Version: 1.0 (Summer 1994)
Evaluation:evaluated by comparison between simulated and experimentally determined catalytic ignition temperatures for stagnation point flows on an electrically heated palladium foil.

2) Surface reactions: Catalytic oxidation of hydrogen over rhodium

Version: 1.1 (2012)
Evaluation: evaluated on steady-state experimental measurements in stagnation-point reactor over Rh/Al2O3 catalyst at 673 -873K; experimentally determined catalytic ignition temperatures for stagnation point flows of H2/O2mixtures; experimentally measured species profiles in annular flow reactor (320 – 970K). Surface kinetics is thermodynamically consistent for a temperature range 273 – 1273K.
