Hydrogen/nitrogen dioxide kinetics - Derived data for the reaction H2 + NO2 = HONO + H at 833 K

New experimental data are reported for the reaction of H2 with NO2 at temperatures near 833 K and pressures of 1.2-5.0 atm. Numerical predictions from a previously published reaction mechanism are in good agreement with the measured species profiles at 833 K only when the recommended rate constant f...

description New experimental data are reported for the reaction of H2 with NO2 at temperatures near 833 K and pressures of 1.2-5.0 atm. Numerical predictions from a previously published reaction mechanism are in good agreement with the measured species profiles at 833 K only when the recommended rate constant for the reaction is reduced by a factor of 30. The rate data derived here are in good agreement with the theoretical expression of Park et al. (1998). Steady state analyses of a simple five-step mechanism are used to develop an analytical expression for NO2 consumption that predicts well the high-pressure data. (AIAA)
