Abstract
Procedimento per la purificazione di gas inerti contenenti impurezze di natura organica, in particolare di gas (azoto) provenienti da reattori di policondensazione allo stato solido di resine poliestere comprendente il trattamento del gas con la quantità stichiometrica (o leggermente superiore) di ossigeno rispetto alle impurezze presenti, a temperatura tra 250° e 600°C impiegando catalizzatori al Pt o Pt/Pd supportati su un solido poroso ed il riciclo del gas direttamente al reattore di policondensazione previo essicamento al fine di eliminare l'acqua prodotta nella reazione di ossidazione delle impurezze.
