Abstract

The progressive deactivation of isopropyl alcohol dehydration over the chrominophosphate catalysts was studied by a continuous-flow micro-reactor in the temperature range of 423-573 K at atmospheric pressure. The deactivation of the catalyst is mainly due to coke deposit, rather than the presence of water. The deactivation kinetics is first order and the decaying phenomena can be described by the shrinking core model. The coke deposition was correlated by the modified Voorhies empirical equation. Coke deposition on an active site would influence the activities on its neighboring sites.
