Combustion analysis of a novel fuel and oxidizer mixture consisting of 50% hydrogen peroxide (by weight with water) and methanol was conducted in a constant volume hot gas combustor. Highly diluted hydrogen peroxide was chosen to reduce the handling difficulties associated with high test peroxide. Despite the presence of copious amounts of water in the reactant stream, ignition was initiated by H2O2 decomposition on a manganese dioxide catalytic bed, liberating steam and highly reactive oxygen, which react with methanol in the gas phase to produce environmentally benign steam and carbon dioxide. An analysis of the heterogeneous combustion of a stoichiometric mixture of 50% hydrogen peroxide and methanol mixture depicted that combustion proceeds with reasonable ignition delays to produce hot gaseous products, leading to rapid increments in chamber pressures. Approximately 1 ml of the mixture was combusted within the chamber using four glow plugs at varying chamber pressures of 0, 2, and 4 bar (gauge). The homogeneous gas phase combustion was simulated using a closed volume reactor in Chemkin. The experimental and theoretical results were compared to better comprehend the ignition and combustion phenomena.
