Catalytic Degradation of High-Density Polyethylene over a Clay Catalyst Compared with Other Catalysts

The catalytic activity of a clay catalyst was studied through the degradation of high-density polyethylene (HDPE) using a thermogravimetric (TG) and fixed bed batch reactor and comparison of that with other catalysts (HZSM-5, all-silica MCM-41, Al2O3, and CaO). The results of TG experiments showed that clay had the same catalytic effects on degradation temperature as Al2O3 and CaO, while HZSM-5 and MCM-41 were able to shift the degradation...
