Han Buxing’s group at the CAS Institute of Chemistry, in collaboration with researchers from Beijing Normal University, Peking University, etc., have used layered self-supporting molecular sieves as catalysts to achieve > 90% conversion of polyethylene plastics into high-quality gasoline under low-temperature, no-noble-metal, no-hydrogen, and no-solvent conditions. The liquid product is primarily composed of branched alkanes (selectivity of 72%), affording a high research octane number of 88.0 that is comparable to commercial gasoline (86.6).
