| Abstract: | Mounting concerns about green house gas emissions as well as increasing demands for energy have been encouraging the use of alternative fuels such as those gases derived from biomasses, which are made up primarily of methane and carbon dioxide. Safety and potential hazard considerations associated with such usage require additional information about the autoignition behaviour of such fuel-air systems when heated. Accordingly, their behaviour was analytically investigated for a homogeneous CH4-O2-CO2 system under constant volume conditions where the dependence of pre-ignition reaction activity and the associated ignition delay were investigated over a wide range of initial key operating parameters, including initial temperature, pressure and mixture composition. These results were compared with the corresponding behaviour of CH4-O2-N2. The role of speeding the reaction rates of such mixtures through the addition of hydrogen was also investigated.
