Extended Data Fig. 1: Catalytic performance of HDPE conversion in a one-stage reactor.

a, Product distribution of HDPE conversion at different temperatures in a one-stage reactor. Reaction conditions: HDPE, 100 mg; LSP-Z100, 12.5 mg; reaction time, 2 h; N2 flow rate, 10 sccm. b, Product distribution of HDPE conversion at different mass ratio of HDPE to catalyst in a one-stage reactor. Reaction condition: HDPE, 100 mg; LSP-Z100, 50 mg / 25 mg / 12.5 mg / 6.25 mg; reaction temperature, 260 °C; reaction time, 2 h; N2 flow rate, 10 sccm. Note that at the 16:1 ratio, the HDPE conversion was 76.4% in two hours, while the rest of the ratios had PE conversion of 100%. c, Product distribution of HDPE conversion at different temperatures in a one-stage reactor with two-catalyst bed. Reaction condition: 100 mg of HDPE and 12.5 mg of LSP-Z100 in the first bed, 100 mg of P-HZSM-5 in the second bed; reaction time, 2 h; N2 flow rate, 10 sccm.
