a The direct hydrogenolysis of single-component PET plastics. Reaction conditions: 0.1 g CuCo/CoOx, 0.1 g plastic, 10 mL 1,4-dioxane, 250 °C, 2 MPa H2, 600 rpm, 12 h. b The direct hydrogenolysis of PET-based mixed plastics. Reaction conditions: 0.1 g CuCo/CoOx, 0.1 g plastics, 10 mL 1,4-dioxane, 250 °C, 2 MPa H2, 600 rpm, 12 h. c The direct hydrogenolysis of PET with additives. Reaction conditions: 0.1 g CuCo/CoOx, 0.1 g of PET plastics, 5 wt% additives, 10 mL 1,4-dioxane, 230 °C, 2 MPa H2, 600 rpm, 10 h. d Comparison of environmental and economic benefits between naphtha-to-PX and PET-to-PX routes. PET refers to polyethylene terephthalate, PX refers to p-xylene.
