A mathematical model of a packed bed reactor was developed to include radial and axial diffusion within the reactor as well as film and pore resistances to both heat and mass flows. The non‐linear partial differential equations which are coupled by a generalized reaction rate expression were finite‐differenced and integrated in the time domain. The performance of the detailed model was compared with those predicted for two simpler models: a homogeneous reactor model and a surface resistance reactor model. The range of variables over which these considerations are important is also indicated.
