Various metal oxides such as BaO, TiO2, MnO2, MoO3 and ZnO have been used as a catalyst for catalytic degradation of polystyrene. In this reaction, the degradation of polystyrene to oil including styrene monomer, ethylbenzene and a-methylstyrene and the selectivity of styrene to ethylbenzene and a-methylstyrene were greatly affected by the acidity and basicity of metal oxides. When metal oxide has more acidic property, the reactivity on degradation is increased but selectivity to styrene was decreased with increase of acidity. |
