    • 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.
    • 延长芳构化催化剂寿命的方法,包括鉴定催化剂的快速失活阈值(RDT),并在达到RDT之前氧化催化剂。 一种芳构化烃的方法,包括鉴定用于芳族化催化剂的快速失活阈值(RDT),以及操作包含催化剂的芳构化反应器以在达到RDT之前延长反应器上的时间。 表征芳构化催化剂的方法包括鉴定催化剂的快速失活阈值(RDT)。 一种延长芳构化催化剂的寿命的方法,包括通过在加速结垢条件下在反应器系统中使用催化剂来预测芳族化反应器的快速失活阈值(RDT),以鉴定测试快速停用阈值(t-RDT),预测 基于t-RDT的芳构化反应器的RDT,并且在预测的RDT之前氧化催化剂以延长芳构化催化剂的时间。
