β¦ Synopsis
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 has been developed for predicting regions of temperature runaway in heterogeneous lixed bed reactors, which is not denendent on te-mnerature nradients. The relationship between this form of instability and that due to multiple steady &es is ex&nined. '.' -SH 500 *

The aim of the present work is to contribute to the analysis of parametric sensitivity in fixed bed reactors using an heterogeneous two dimensional model. The sensitivity functions are calculated along with the state variables and the bound of the region of parametric sensitivity is drawn by the max
Although many theoretical studies are available in the literature dealing with parametric sensitivity and runaway of chemical reactors, experimental studies are relatively few. This paper describes an investigation in which an attempt was made to experimentally verify theoretical results for paramet
