A method of extending the life of an aromatization catalyst comprising identifying a rapid deactivation threshold (RDT) of the catalyst, and oxidizing the catalyst prior to reaching the RDT. A method of aromatizing a hydrocarbon comprising identifying a rapid deactivation threshold (RDT) for an aromatization catalyst, and operating an aromatization reactor comprising the catalyst to extend the Time on Stream of the reactor prior to reaching the RDT. A method of characterizing an aromatization catalyst comprising identifying a rapid deactivation threshold (RDT) of the catalyst. A method of extending the life of an aromatization catalyst comprising predicting a rapid deactivation threshold (RDT) for an aromatization reactor by employing the catalyst in a reactor system under an accelerated fouling condition to identify a test rapid deactivation threshold (t-RDT), predicting the RDT for the aromatization reactor based upon the t-RDT, and oxidizing the catalyst prior to the predicted RDT to extend the Time on Stream of the aromatization catalyst.
