摘要

为探索H2S在多孔介质内超绝热燃烧裂解制硫制氢的机理，采用计算流体力学(CFD)与CHEMKIN相结合的方法，使用标准k-ε湍流模型和一个17组分、57步复杂化学反应机理，模拟了H2S在直径为3 mm的Al2O3圆球堆积成的多孔介质内的燃烧，模拟结果与实验数据基本吻合.模拟结果显示：多孔介质内H2S的燃烧温度超过了绝热燃烧温度，为H2S的裂解制硫制氢提供高温环境，富燃条件下H2S部分地裂解生成单质硫和氢气.另外，对采用的复杂化学反应机理是否适用于多孔介质内H2S燃烧时各向异性火焰的模拟作了有意义的探索.

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.
