General equation for linear mechanisms of catalyst deactivation

A rigorous approach to designing deactivation kinetic models is proposed, based on detail mechanisms of catalytic reaction and deactivation. It is demonstrated that deactivation equations can be derived using the Bodenstain principle of quasi-steady state approximation. A general equation applicable to any linear mechanism is suggested. Several examples are given regarding various reaction mechanisms and deactivation. (c) 2006 Elsevier B.V. All rights reserved.
