Recently, Wijngaarden and Westerterp (1989) derived a dimensionless criterion as to whether or not a homogeneous model can be used instead of a heterogeneous one in modelling wall-cooled tubular reactors. Their work is an extension of the well-known criteria of e.g. Mears (1971) for the neglect of i
## Abstract Unsteadyβstate operations are known to enhance the performance of some packedβbed reactor systems. However, negative effects of this type of operation should not be neglected. Temperature excursions developed during transients may accelerate some deactivation mechanisms, reducing cataly
