Catalyzing the Hydrocracking of Low Density Polyethylene

The hydrocracking of squalane and low density polyethylene (LDPE) into low molecular weight hydrocarbons has been demonstrated with the use of bifunctional zeolite catalysts, Pt-impregnated USY and Beta, with selectivity toward isomers of C4–C6 alkanes. Quantification of liquid and gaseous products via GC-FID and GC-MS demonstrated that appropriate catalyst selection can yield >95% conversion of polymer to fluid products at mild reaction conditions of 330 °C and 20 bar of H2 and short reaction times of
