Instability in the steady state operation of fixed bed catalytic reactors may arise from various sources, the most probable being parametric sensitivity as a consequence of the heterogeneity of the system, leading to temperature runaway, outside of the region of multiple steady states. A technique h

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
Previously reported design criteria for cooled tubular reactors are based on the prevention of reactor temperature runaway and were developed for single reactions only. In this paper it is argued that such criteria should be based on the reactor selectivity, from which eventually a maximum allowable
