The objective of the present work is to realize the kinetic modeling regarding
deactivation of Pt-HY zeolite and monitor the isomerization reaction of n-hexane. The
catalyst has been prepared with o.4% Pt and evaluated during the isomerization reaction
of n-hexane. Based on the results of catalytic investigation, a kinetic model was proposed
to deactivate the catalyst by coke formation. The present method provides information on
apparent overall kinetics as well as deactivation parameters and would seem to provide a
rapid method for screening of reaction/deactivation behavior. Accordingly the
deactivation order was found to be 3.72. The obtained correlation of deactivation predicts
the activity pattern under the applied reaction conditions, closely mimics those observed
experimentally, and spans those obtained from empirical correlations.
