摘要:
利用流体力学与化学动力学相结合的方法,探索高浓度过氧化氢在多孔介质(银网或复合离子催化剂)内的分解反应机理.采用Fluent流体仿真软件模拟过氧化氢在使用银网作为催化剂的催化床内的分解反应,分析过氧化氢的分解温度场分布及反应物和产物的组分分布等,讨论不同尺寸、质量流量和壁面条件对温度场和组分分布的影响.结果表明:数值仿真能够较真实地反应过氧化氢的催化分解过程,可为进一步的试验提供可靠的理论依据.
Abstract:
In combination of the hydrodynamics and the chemical kinetics, the decomposition mechanism of high test hydrogen peroxide in the porous media(silver mesh or composite ion catalyst)is explored. Fluid simulation software Fluent is employed to simulate the decomposition of hydrogen peroxide in the catalyst bed of the silver mesh. The decomposition temperature field distribution of hydrogen peroxide and the component distribution of reactants and products are analyzed. The effects of different sizes, mass flows and wall conditions on the temperature field and composition distribution are discussed. The results reveal that the numerical simulation can present the catalytic decomposition process of hydrogen peroxide well, which provides reliable theoretical basis for the further experiments.
