摘要
叙述了钙基固硫剂固硫反应的原理,反应中所存在的五个主要阻力。简化反应过程,独立出固硫反应的产物层扩散阻力,推导出产物层扩散的数学模型;由试验数据,求得产物层扩散系数Ds。
The paper has explained the theory of sulfation of calcium-based sorbent and five kinds of capital resistance existing during reaction process.Based on hypotheses given,the reaction process is simplified,isolating the diffusive resistance through product-layer from others.A mathematical model for diffusion coefficient through the product-layer has been deduced.On basis of experimental data,the model has been solved,obtaining gas diffusion coefficient Ds.
