The catalytic degradation of a mixture of polyethylene (PE) and polystyrene (PS) was investigated in a semi-batch reactor. The influence of the nature of the cracking catalyst and the reaction temperature was also studied. The main degradation product was liquid oils with gasoline range carbon number distributions. Natural clinoptilolite zeolite (HNZ) exhibited an equivalent catalytic performance to silica-alumina (SA). The HZSM-5 catalyst produced the highest amount of gaseous products. An increase in the degradation temperature resulted in a decrease in ethylbenzene and propylbenzene, but an increase in styrene. A Thermogravimetric analysis revealed an interaction between PE and PS in the catalytic degradation.
