Abstract
Hydro-carbon thermal ignition processes were analyzed by using the tools developed by the authors, "Contribution Matrix" and "Atomic Balance". It was proposed to explain the thermal ignition process from four view points, H2O2 Chemistry, HO2 Chemistry, H2-O2 System Chemistry and CO2 Chemistry. In case of the pure Hydrogen-Oxygen system, Reaction of (R12) OH+H2→H2O+H plays a significant role. In case of Hydrocarbon thermal ignition, however, contribution of this reaction is not important because of the lower H2 concentration. (R13) CO+OH→CO2+H plays a predominant role in place of (R12). The only path to generate CO2 is this reaction. In the H2O2 Chemistry dominant regime, (R12) convert CO slowly into CO2. The mafor portion of CO2 is generated by the same reaction during the final stage of the H2-O2 System Chemistry.
