As implemented in Cantera, the activation energy in the BMA expression is calculated from the reaction enthalpy evaluated at the current system temperature, not a reference temperature of 298 K. The species' enthalpies are calculated using NASA polynomials as a function of temperature. The activation energy in the BMA rate parameters is therefore slightly a↵ected by the temperature, causing a small deviation from the Arrhenius rates. Thus, minor di↵erences between CMPO and CMPO-BMA models are observed in the synthesis gas conversion and full oxidation yield. showing di↵erences in reactions that are relatively insensitive, and the sensitivity ranks of the two base models are more alike at higher C/O inlet ratio.
