Abstract
"PROCESSO PARA RECICLAGEM QUìMICA DE POLI (TEREFTALATO DE ETILENO) PóS-CONSUMO E EQUIPAMENTO PARA REALIZAR RECICLAGEM QUìMICA DE POLI (TEREFTALATO DE ETILENO) PóS-CONSUMO". Compreendendo um processo químico que realiza a despolimerização de poli(tereftalato de etileno) - PET - com o intuito de promover a reciclagem química pós-consumo desse polímero. Descreve, ainda, o equipamento necessário para a sua execução. Tal processo está baseado em reação de hidrólise, a qual ocasiona a ruptura das ligações éster formadas entre os precursores do polimero (ácido tereftálico e etileno glicol) quando de sua polimerização. o objetivo é recuperar, a partir de sucata de PET e de PET pós-consumo, o ácido tereftálico e o etilenoglicol. A vantagem da presente patente são as condições de trabalho em pressões de baixa a moderada, em temperaturas de 215 a 450 <198>C, que permitem, atingir o nivel energético necessário para a desejada hidrólise do PET, e simultaneamente promover a separação e purificação do ácido tereftálico e etilenoglicol e/ou outro glicol presente na formulação do PET formados nessa reação de hidrólise. o produto obtido nessa reciclagem é o ácido tereftálico e o etilenoglicol, que dessa forma fecha o ciclo de vida do PET fazendo-o retornar às suas matérias primas, evitando seu acúmulo na biosfera do planeta.
