This study demonstrated the non-thermal plasma-assisted hydrogenolysis of high-density polyethylene at room temperature, producing light alkanes with high selectivity. The findings highlight a novel strategy for upcycling plastics to valuable hydrocarbons under ambient conditions.
Upcycling is an attractive approach for valorization of waste plastics to valuable chemicals. Here we report the first case study of non-thermal plasma-assisted hydrogenolysis of high-density polyethylene (HDPE) to C-1-C-3 hydrocarbons. Light alkanes, predominately CH4, C2H6 and C3H8 with >95% selectivity, were obtained under ambient condition as result of favorable thermodynamics and fast reaction kinetics. The findings demonstrated that hydrogenolysis that typically demands above 300 degrees C with thermal catalysis can occur at room temperature in assistance of non-thermal plasma. This proof-of-concept study showcases a novel strategy for upcycling of plastics to valuable hydrocarbons under ambient condition.
