Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 49 N° 5 (Mars 2010) . - pp. 2064–2069 Titre : Operating conditions for the pyrolysis of poly-(ethylene terephthalate) in a conical spouted-bed reactor Type de document : texte imprimé Auteurs : Maite Artetxe, Auteur ; Gartzen Lopez, Auteur ; Maider Amutio, Auteur Année de publication : 2010 Article en page(s) : pp. 2064–2069 Note générale : Industrial Chemistry Langues : Anglais (eng) Mots-clés : Pyrolysis  Poly-ethylene terephthalate  PET  Conical reactor  plastic Résumé : Continuous pyrolysis of poly-(ethylene terephthalate) (PET) was performed in a conical spouted-bed reactor. This reactor is especially suitable for this process, because of its excellent hydrodynamic behavior and its versatility. An optimization of the operating conditions has been performed to avoid particle agglomeration and defluidization, given that these are serious problems that hinder plastic waste pyrolysis. Moreover, the influence of temperature in the pyrolysis product distribution was studied in the range of 500−600 °C. PET pyrolysis led to a high yield of gas fraction, a low amount of liquids, a significant yield of solid fraction, and a solid residue that remained in the reactor coating sand particles. The main products obtained are carbon monoxide, carbon dioxide, benzoic acid, and acetaldehyde. Note de contenu : Bibliogr.
