description	The invention relates to 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, and the protective bed (11) removes high-boiling organic substances or organic substances, with a high combustion temperature, from the process gas stream. La presente invención está relacionada con un método para procesar una mezcla de material de poliéster reciclado y un prepolímero de poliéster de un proceso de fabricación de poliéster, en donde un material de poliéster reciclado se mezcla con un prepolímero de poliéster de un proceso de fabricación de poliéster y se trata en un reactor de tratamiento térmico a granel (7) con un gas de proceso en contracorriente o contracorriente a la dirección de flujo de la mezcla. En este proceso, el gas de proceso pasa a través de un lecho protector (11) que contiene un material adsorbente sólido que elimina sustancias orgánicas de alto punto de ebullición o sustancias orgánicas con alta temperatura de combustión de la corriente de gas de proceso, antes de entrar en un recipiente de catalizador (14).
