ON THE SOLUTION OF A MODEL CASE F DEACTIVATION BY SITE POISONING ND PORE BLOCKAGE

Abstract

The problem of deactivation by active site poisoning and pore blockage is analyzed. A solution technique is presented which considerably simplifies the numerical effort involved in the analysis of the problem. For problems with slab geometry, in particular, closed form solutions are developed which can be conveniently utilized in reactor design problems.

Numerical examples are presented which show that the effect of pore blockage can be quite detrimental to the life of the catalyst, sometimes even more so than the effect of site coverage by a poison.

KEYWORDS:

• Deactivation
• Pore blockage
• Site poisoning
• Catalyst
