Abstract
This invention relates to a process for regeneration of a zeolite catalyst, specifically an aluminosilicate zeolite with germanium substituted in the framework for silicon and with platinum deposited on the zeolite. The catalyst may be used in a process for aromatization of alkanes, specifically C-Calkanes. The regeneration process 1) removes coke and sulfur from the catalyst via oxidation, 2) redisperses platinum on the surface of the catalyst via chlorine gas, 3) removes chlorine and bind Pt to the surface of the zeolite by steaming, 4) reduces the catalyst in hydrogen, and 5) optionally, resulfides the catalyst. The zeolite may be a MFI zeolite. The catalyst may be bound with an inert material which does not act as a binding site for platinum during the regeneration process, for example, silica.
