Abstract

A process for activating an aromatization catalyst includes contacting an aromatization catalyst with a carburizing gas in a carburization reactor at a carburization pressure in a range of greater than 300 kPa to 800 kPa, or 500 kPa to 600 kPa, to obtain a calcined aromatization catalyst. The carburizing gas provides a carbon source, preferably the carburizing gas comprises at least one of methane, ethane, propane, butane, or carbon monoxide.
