An updated combustion kinetic model for syngas fuels and C₁ oxygenates

The present work addresses updating the recent C1 model of Li et al. (IJCK, 2007) based upon the recently updated H₂ combustion model of Burke and co-workers (IJCK, accepted) as well as further considerations of recent work on the kinetics of CO, CH₂O, and CH₃OH. A larger validation range as well as more recent experimental and theoretical studies of sensitive reactions such as OH+CO→Products, CO+HO₂→CO₂+H and CH₃OH+HO₂→Products are considered. Predictions of the current updating compare favorably with those using the Li et al. experimental validation targets, as well as additional burning velocity and ignition delay experiments spanning larger pressure ranges and dilution with H₂O or CO₂. The updated model will serve as a core around which to construct kinetic models for larger hydrocarbons and oxygenates.
