Beschreibung
Zusammenfassung:	A method for processing a mixture of recycled polyester material and a polyester prepolymer from a polyester manufacturing process, wherein a recycled polyester material is mixed with a polyester prepolymer, from a polyester manufacturing process, and treated in a bulk thermal treatment reactor (7) with a process gas which flows in a counter-current or a cross-current flow direction to the flow direction of the mixture. In this process, the process gas, before entering a catalyst vessel (14), is passed through a protective bed (11) containing a solid adsorbent material that removes high-boiling organic substances or organic substances, with a high combustion temperature, from the process gas stream.
