Sensitivity Analysis of Tubular Packed-Bed Reactor by Pseudohomogeneous 2-D Model
The sensitivity behavior of the fired-bed catalytic reactors is examined using the pseudohomogeneous two-dimensional model with radial dispersion for the first-order irreversible reaction. The sensitivity criteria developed are tested. The relations between self-similarity and thermal runaway are studied. The pseudoadiabatic type of operation is taken into consideration. The boundaries of the sensitivity region in the space Da-Pe are compared with those predicted by the standard one-dimensional model and the criterion of Hagan et al. The sensitivity behavior of the system in the space alpha-Bi is also discussed.
