Abstract
Thermal and catalytic cracking of waste high density polyethylene, HDPE (Discarded yoghurt bottles), using CuO/Al2O3 catalyst at 430-5200C into fuel oils were carried out using a self-designed stainless steel laboratory reactor. Waste HDPE was cracked into liquid fuel oil, solid residue and gaseous hydrocarbon products. It was observed that catalytic cracking, using CuO/Al2O3 catalyst, had lower degradation temperature, faster gaseous and liquid product generation rate and higher yield of paraffinic hydrocarbons than thermal cracking. In contrast, thermal cracking had higher yield of liquid product and more olefinic hydrocarbons than catalytic cracking. GC-MS analysis results gave the compositions of the liquid products of thermal and catalytic cracking to be in the range of C8-C24, and distributed between paraffinic and olefinic hydrocarbons.
