Catalytic Degradation of HDPE Below 200°C by dpagor is a document available to read on EtoBox.
1) High density polyethylene (HDPE) can be catalytically degraded at temperatures as low as 200°C using finely dispersed superacid catalysts like Pt-stabilized ZrO2/SO4 at high loadings (50-70%), allowing for degradation of HDPE and waste plastics below usual pyrolysis temperatures of 400°C. 2) Maximum degradation rates were achieved at 200°C and 600 psig H2 when using Pt-stabilized ZrO2/SO4 at 50% loading, while minimal degradation occurred using non Pt-stabilized ZrO2/SO4 or HZSM-5 catalysts at the same
