Abstract

New rate constant determinations for the reactions (1), (2), (3) were made at 1000 K by fitting species profiles from high-pressure flow reactor on moist CO oxidation perturbed with methane. The experiments were selected to minimize the uncertainty in the rate constant determinations. This uncertainty was estimated using model sensitivity coefficients, derived for time-shifted flow reactor experiments. The model sensitivity analysis was also used to characterize the mechanistic dependence on the new rate constant values. Linear sensitivities of the fitted rate constants to the unfitted values are given. Singular value decomposition was used to determine which of these four could affect the fitted rates without changing the fit norm.
