The regeneration process of waste zeolites has been studied in order to find areas for their further usage. The physicochemical characteristics of zeolites after regeneration have been determined. By rising of temperature in the regeneration from 200oC to 400oC, an increase in the specific surface area is observed. In this temperature range, it occurs coke removal, that is, desorption of strongly adsorbed products in large and small cavities of zeolite.
