Experimental and kinetic modeling investigation on laminar flame propagation of CH4/CO mixtures at various pressures: Insight into the transition from CH4-related chemistry to CO-related chemistry

In this work, laminar flame speeds of CH4/CO/air mixtures were measured at the unburnt temperature of 353 K and pressures from 1 to 10 atm in a high-pressure constant-volume cylindrical combustion vessel. Effects of pressure, equivalence ratio and CO content in CH4/CO mixtures on laminar flame speeds were investigated. A kinetic model for CH4/CO combustion was developed based on recent progress in elementary reactions and validated against...
