Abstract:
1. A method of aromatizing a hydrocarbon comprising: contacting the hydrocarbon with an aromatization catalyst comprising a crystalline aluminosilicate within a commercial-scale aromatization reactor to produce aromatic hydrocarbons; identifying, in situ within the reactor, a rapid deactivation threshold (RDT) of the catalyst, wherein identifying the RDT further comprises identifying a point or range at which a fouling rate of the catalyst as a function of Time on Stream becomes non-linear; identifying a point or range at which a fouling rate of the catalyst as a function of reactor temperature becomes non-linear; identifying a point or range at which a fouling rate of the catalyst as a function of a halogen content of the catalyst becomes non-linear; or identifying a critical amount of halogen required in the catalyst to inhibit catalyst deactivation during aromatization; and oxidizing, in situ within the reactor, the catalyst prior to reaching the RDT.
