✦ Synopsis

Ah&act-Effectiveness factor correlations are derived for the kinetic model describing a pseudo firstorder mechanism up to the point of penetration in the catalyst pellet at which the non-key reactant is completely consumed. The pseudo first-order approximation is shown to be satisfactory for the rate equation describing the hydrogenation of ethylene on a copper-magnesia catalyst, and the model predictions are found to be in good agreement with previously published experimental results for this system.

The selectivity of two first-order, parallel reactions, one reversible and one irreversible, can be altered substantially by the presence of an intraparticle diffusion resistance. At very large resistances, the relative selectivity approaches an asymptotic limit which depends on the kinetic, transpo
