✦ Synopsis

An algorithm for simulation and optimization of adiabatic fixed-bed reactors subject to catalyst deactivation is developed. It is applied to the low-temperature CO converter, the kinetic model for which is deduced from some industrial data and considering chlorine as the main cause of catalyst poisoning. Sintering is not considered due to the short range of variation of temperature in the catalyst bed. Optimal inlet temperature trajectories are determined to maximize the obtained total amount of reaction over a fixed operation time. Approximate optimal trajectories in discrete steps of temperature are proposed to be followed in industrial practice.

Theoretical and experimental work on tubular reactors has shown that a high temperature reaction zone can be induced to move counter to the flow of reactants by conduction and/or radiation through the solid phase. This naturally occurring phenomenon represents a transient mode of operation that can
