| Popis: | An existing, validated elementary reaction model for hydrogen oxidation in supercritical water, with theoretically consistent modifications for high pressure, was expanded to allow modeling of carbon monoxide oxidation. The carbon monoxide model was less successful, exhibiting a higher overall activation energy than the data and lacking an oxygen dependence. Data for fuel-rich CO oxidation, including hydrogen formation, were well predicted, but results for fuel-lean conditions were not correctly predicted. Both models, when extended to subcritical conditions, successfully reproduced the majority of the experimentally observed pressure (water-density) dependence |
