Polyethylene terephthalate (PET) and CO2, two chem. wastes that urgently need to be transformed in the environment, are converted simultaneously in a one-pot catalytic process through the synergistic coupling of three reactions: CO2 hydrogenation, PET methanolysis and di-Me terephthalate (DMT) hydrogenation. More interestingly, the chem. equilibrium of both reactions were shifted forward due to a revealed dual-promotion effect, leading to significantly enhanced PET depolymerization The overall methanol yield from CO2 hydrogenation exceeded the original thermodn. equilibrium limit since the methanol was in situ consumed in the PET methanolysis. The degradation of PET by a stoichiometric ratio of methanol was significantly enhanced because the primary product, DMT was hydrogenated to di-Me cyclohexanedicarboxylate (DMCD) or p-xylene (PX). This synergistic catalytic process provides an effective way to simultaneously recycle two wastes, polyesters and CO2, for producing high-value chems.
