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
This paper discusses an application of the fractal pore model introduced by Coppens and Froment (1994a,b): the gas phase production of vinyl acetate from ethylene and acetic acid on a Pd/AI203 catalyst. The true fractal morphology of the alumina surface has to be accounted for, because the predicted
