Catalytic upcycling of waste polyethylene to fuels over a nanosized beta zeolite under mild conditions

Abstract

We herein report that a nanosized beta zeolite can achieve the upcycling of waste polyethylene into gasoline-range fuels under mild conditions. High accessibility to rich acidic sites intrinsic to the nanosized beta zeolite is crucial to the cracking of polyethylene, leading to a high fuel yield of over 90% at 250 °C for 3 h.
