The present invention relates to a method for regenerating polyester waste and a regeneration device thereof, wherein polyethylene terephthalate (PET) is converted into dimethyl terephthalate (DMT) and ethylene glycol (ethylene glycol), which are polyester raw materials. It relates to a regeneration method for raw material and a regeneration device thereof. More specifically, the present invention relates to a novel continuous regeneration method for recycling the produced methanol and achieving the efficiency and energy saving effect of the process through the crystallization process of dimethyl terephthalate.n n n n Methanolysis, glycolysis, depolymerization, dimethyl terephthalate, raw materialization, polyethylene terephthalate |
