Resumen

Los materiales poliméricos están cada vez más presentes en la vida cotidiana y son desechados a gran escala, constituyendo un reto para su reciclaje. Este trabajo estudió la despolimerización por microondas de residuos de poliestireno expandido (EPS) utilizando negro de carbón como catalizador. La pirólisis catalítica se investigó en cinco proporciones de catalizador a polímero (0,0125:1, 0,125:1, 0,25:1, 0,5:1, 1:1). La pirólisis asistida por microondas tuvo lugar a 400 W en un tiempo fijo de 12 minutos. Se realizaron espectroscopia infrarroja por transformada de Fourier (FTIR) y análisis termogravimétrico (TGA) para evaluar la despolimerización. El mayor rendimiento de gases no condensables se obtuvo en la relación 0,25:1 con un rendimiento de gas del 53%. El análisis FTIR de la fracción líquida en la proporción 0,25:1 mostró nuevas bandas de absorción y nuevos picos de degradación a temperaturas más bajas se observaron en termogravimetría en comparación con los residuos de EPS. Este estudio demostró la posibilidad de despolimerización de EPS mediante microondas utilizando estructuras carbonosas, lo que puede contribuir al reciclaje de EPS.
