This study numerically investigates a two-dimensional physical model of methane/air mixture combustion in catalytic and non-catalytic porous media. The temperature distribution and flame stability of combustion in inert alumina (Al 2 O 3) pellets and platinum (Pt) catalyst-supported alumina (Al 2 O 3) pellets, were studied by changing the burner structure, operating parameters, and physical properties of alumina pellets. The simulation results indicated that the gas temperature in the inert porous medium is higher than that in a catalytic porous medium, while the solid temperature in an inert porous medium is lower than that in a catalytic porous medium. The flame moved toward the burner exit with the increasing diameter of the packed pellets at a lower equivalence ratio and moved toward upstream with the increased thermal conductivity of packed pellets. The flame location of the catalytic porous burner was more sensitive to the flame velocity and insensitive to thermal conductivity compared to the inert porous burner. The distance of the flame location to the burner inlet is almost constant with the increasing length of the porous media for both the catalytic and inert porous burner, while the relative position of the flame location moved toward the upstream.

“…To the best of our knowledge, this is the first paper presented on partial oxidation of a gasifier product gas using the reverse-flow concept. Previous work in this field has been focused on partial oxidation of pure methane or natural gas [18][19][20][21][22]. The reforming of a gasifier product gas presents unique challenges as the gas contains not only methane but also hydrogen and other hydrocarbons.…”

This is the published version of a paper published in Journal of Computational Methods in Sciences and Engineering.Citation for the original published paper (version of record):Tunå, P., Svensson, H., Brandin, J. (2015) Modelling of a reverse-flow partial oxidation reactor for synthesis gas production from gasifier product gas.. Abstract. Biomass gasification followed by fuel synthesis is one of the alternatives for producing liquid fuels and chemicals from biomass feedstocks. The gas produced by gasification contains CO, H2, H2O, CO2, light hydrocarbons and tars. The light hydrocarbons can account for as much as 50% of the total energy content of the gas, depending on the type of gasifier, operating conditions and feedstock. The gas also contains catalyst poisons such as sulphur, in the form of H2S and COS. This paper presents simulations of a reverse-flow partial-oxidation reformer that converts the light hydrocarbons into more synthesis gas, while achieving efficiencies approaching that of conventional catalytic processes. Variations in parameters such as pressure, amount of oxidant and steam-to-carbon ratio were also investigated. Simulations of the reforming of natural gas were included for comparison. The results show the benefits of using reverse-flow operation with lean gases such as gasifier product gas. Journal of Computational Methods in Sciences and
