Abstract: In order to probe into the mechanism of production of sulfur and hydrogen in the super-adiabatic combustion of hydrogen sulfide in porous media, computational fluid dynamics (CFD) was employed combining with CHEMKIN to model the combustion of hydrogen sulfide in porous media of a 3-mm-diameter-Al₂O₃-sphere packed bed.The standard k-ε turbulence model and a 17-species, 57-elemental reaction mechanism were used in numerical simulation.The numerical results showed good agreement with the experimental data.The combustion temperature exceeded the theoretical combustion temperature which offered a high temperature for the decomposition of hydrogen sulfide.Sulfur and hydrogen could be obtained through combustion in porous media in rich-fuel condition.The numerical results also showed that the combination of CFD with complex chemical reaction mechanism performed well in modeling the anisotropic flame of hydrogen sulfide in porous media.
