Modelling of Catalyst Pellet Poisoning for Benzene Hydrogenation

Based on the kinetic of benzene hydrogenation, pore diffusionand catalyst deactivation, time- dependent effectiveness behaviorof a single Ni- SiO2-Al2O3 catalyst pellet where the chemicalreaction rate is determined by pore diffusion was simulated fordifferent conditions of operation. Poisoning kinetics were measured in a series of differentialreactor experiments at atmospheric total pressure at temperaturesranging from 403 to 473 K. A computed effectiveness factor has been compared withexperimental values for a catalyst pellet of industrial size. Agood degree of correlation between theoretical prediction and theexperimental results was found.
