Abstract

The effect of catalyst structure, acidity, and Ga addition of zeolites on the pyrolysis of polypropylene (PP) was investigated by comparing PP cracking efficiency and product distribution properties in this study. Thermogravimetric analysis result indicated that HY(SiO₂/Al₂O₃; 30) is the most effective catalyst lowering PP decomposition temperature, followed by Ga/HZSM-5(30), HZSM-5(30), HZSM-5(80), and HZSM-5(280). Meanwhile, Ga/HZSM-5(30) revealed the lowest apparent activation energy (Ea), 110 kJ/mol, than HY(30) (159 kJ/mol), and other HZSM-5 catalysts (122 ~ 172 kJ/mol), suggesting its high efficiency lowering Ea on PP pyrolysis. Py-GC/MS results also suggested that Ga/HZSM-5 produces the largest amount of aromatic hydrocarbons, followed by HZSM-5(30), HZSM-5(80), HY(30), and HZSM-5(280). The increase of Ga/HZSM-5(30) amount on PP pyrolysis led the further decrease of Ea value and increase of aromatics production efficiency.
