Summary

The performance of pyrophyllite and halloysite clays in the degradation of polystyrene (PS) was investigated. The degradation was carried out in a semi-batch reactor with a mixture of polystyrene and catalysts at 400-450oC. The catalysts showed good catalytic activity for the degradation of PS with high selectivity to aromatics liquids. Styrene is the major product, and ethylbenzene is the second most abundant one in the liquid product. The catalytic degradation showed much less production of styrene dimers and higher selectivity to ethylbenzene than the thermal degradation did. High degradation temperature favored the production of styrene monomer, but it decreased the ethylbenzene production.
