摘要
A rigorous mathematical model based on the dusty gas model is developed to investigate the phenomenon of diffusion and chemical reaction in porous catalyst pellets for the steam reforming and methanation reactions under industrial conditions. Two simplified Fickian type diffusion reaction models are also developed and their results are compared with the results of the rigorous model. Parametric investigations on the single catalyst pellet are carried out using the dusty gas model as well as the simplified models in order to obtain a deeper insight into these complex catalytic gas-solid systems and to explore regions of applicability of the simplified models. The phenomenon of negative effectiveness factors is also investigated.
