摘要：
In this work, the synergistic effect of the gamma-ray irradiation and catalyst on the pyrolysis of High-Density Polyethylene (HDPE) waste was investigated in a batch reactor. Two catalysts, Zeolite Socony Mobil-5 (ZSM-5) and Ferric oxide, were used, and their loading was optimized. The results revealed that the degradation temperature significantly reduced with increasing dosage of irradiation. The complete pyrolysis of HDPE waste occurs at a temperature of 400 degrees C and reaction time of 240 min (4 h), while in a case of irradiation-induced pyrolysis, there is higher yield and decrease in the residence time of pyrolysis. Irradiation with a higher dosage (2,000 kGy) increases the rate of thermo-catalytic pyrolysis for HDPE waste and gives maximum conversion.
