The report gives results of the evaluation of a large set of chemical reactions describing methane/air combustion to determine the significant reactions at atmospheric pressure, at temperatures of 1500-2500K, and at equivalence ratios of 0.8-1.25. The reactions were screened to eliminate: reactions with negligible net contribution to heat evolution or pollutant formation, species with no discernible effect on major species or temperature, and groups of reactions constituting only species exchange loops. A set of 26 reactions/17 species was derived which can duplicate within 5 percent the predictions of the 134-reaction/25-species master set. Ten additional pyrolysis reactions are cited for low-temperature and fuel-rich applications. The Zeldovich mechanism is the principal route to NO for stoichiometric combustion, but under lean conditions, a path to NO involving N2O is also active. For fuel-rich conditions, comparison with stirred reactor data suggests that NO formation cannot be explained by the Zeldovich mechanism alone: an alternate path involving species of the type RN may be of importance. Finally, prompt NO arising from oxygen-atom overshoot was not predicted for an idealized plug flow ignition case.
