the rate constants for the reactions
HO2 + OH, OH + OH, and HO2+HO2 were updated based on recent determinations.
The predicted H2 oxidation rate
was sensitive to the rate of the HO2 + OH reaction, particularly at lean conditions, and the present data support
recent values for the rate constant.

pressure of 50 bar, temperatures in the range of
700–900 K
initiated at 748–775 K and reaction is completed
at a temperature of 825 K
shows results for stoichiometric
conditions (U = 1.03). Here, the onset of reaction
is shifted to slightly higher temperatures,
798–823 K. The present mechanism predicts a
slightly faster consumption rate for H2 than the
model of Burke et al
in a laminar
flow reactor at 50 bar pressure and temperatures
of 700–900 K. Results provided information
about the onset temperature for reaction and the
H2 consumption rate upon initiation at conditions
above the third explosion limit.
