## Abstract The sensitivity behavior of the fixedβbed catalytic reactors is examined using the pseudohomogeneous twoβdimensional model with radial dispersion for the firstβorder irreversible reaction. The sensitivity criteria developed are tested. The relations between selfβsimilarity and thermal r

Most existing criteria for predicting the critical residence time (or jlow rate) at which runaway occurs in an adiabatic catalytic packed-bed reactor do not account for interphase heat-transfer resistance and intraparticle diffusion. When these transport limitations exist, the critical residence tim
## Abstract The countercurrent backmixing model of a fluidized bed reactor predicts axial concentration profiles quite different from those suggested by simple twoβphase models. The models can also be distinguished in terms of the dependence of conversion on operating variables. An experimental st
The performance of different two-dimensional models of fixed bed catalytic reactors is analyzed for different situations. The deviation of the response of the simplified models with respect to the heterogeneous one is explained in terms of the operative conditions and the value of dimensionless grou
