Numerical simulation of hydrogen production in porous media from hydrogen sulfide by partial oxidation
多孔介质内H2S贫氧燃烧制氢数值模拟

In order to probe into the mechanism of recovery of sulfur and hydrogen from hydrogen sulfide in porous media by superadiabatle partial oxidation, the combination of computational fluid dynamics and ehemcial kinetics investigation was employed to model the filtration combustion of hydrogen sulfide in a 3-mm-diameter-Al2O3 -sphere packed bed through a 17-species, 57-elemental reaction mechanism. The results of the simulation show good agreement with experimental data. The numerical results also show that the combustion temperature exceeds the theoretic combustion temperature, which can offer the high-temperature environment for the decomposition of hydrogen sulfide to produce hydrogen and sulfur.
