Catalytic upcycling of waste plastics over nanocellulose derived biochar catalyst for the coupling harvest of hydrogen and liquid fuels

A powerful simple biochar catalyst derived from nanocellulose was applied to the catalytic upcycling of waste plastics into H2 and liquid fuels for first time. For results model low-density polyethylene (LDPE) pyrolysis, C8-C16 aliphatics monocyclic aromatics were dominant constitutes product with yields ranging 22 68 wt%. At temperature 500 °C LDPE ratio surpassing 3, could be completely degraded gas without wax production. yield 16 wt% observed at 450 4, which dramatically lower than that (77 wt%) absence °C. Up 92 vol% detected in gaseous a 36 The temperatures higher ratios favored increasing generation expense light CnHm especially CH4. Moreover, this tested effectively convert real including grocery bags packaging tray valuable H2-enriched gas.
