A Mathematical Model for Diffusion Coefficient through the Product-layer of Desulfurizer Particle in Sulfation Reaction |
| |
| Abstract: | 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. |
