The decline in activity of a commercial\* supported catalyst has been interpreted using a model of reolitic micropores uniformly distributed within a network of macropores representing the silica/alumina support. Using this model. simultaneous deactivation by site coverage end pore plugging can be s

A theoretical framework has been assembled for elucidation of the deactivation of a supported zeolite cracking catalyst used in a fixed bed, plug flow reactor. Intraparticle processes are based upon a parallel bundle model for the macropores and mesopores associated with the sihca alumina support. Z

## Abstract The problem of simultaneous convection, diffusion and reaction inside a porous catalyst slab is considered. A combination of perturbation and integral mathematical techniques are used to derive approximate analytical solutions for the concentration and temperature profiles, as well as f
