This paper studies experimentally and numerically rich combustion of methane and propane inside inert porous media to examine the suitability of the concept for hydrogen production. Temperature velocities and chemical products of the combustion waves were recorder experimentally at the equivalence ratio range from stoichiometry (φ = 1.0) to φ = 2.5, at a filtration velocity of 12 cm/s. Two-temperature numerical model based on comprehensive heat transfer and chemical mechanisms was developed and found to be in a good agreement with experimental data. It is observed that the products of methane and propane partial oxidation (H2, CO, and C2 hydrocarbons) are dominant for ultrarich superadiabatic combustion where up to 60% and 55% of fuel, respectively, is converted to CO and H2. Propane conversion to hydrogen was significantly higher than for methane.
