| Abstract: | Catalytic effects of alkali earth oxides and transition metal oxides on pyrolysis of waste polystyrene is studied and influence of alkalescence of catalysts on pyrolysis products is researched. A catalyst CaO as its main component, MgO and NaOH as auxiliary is developed. Experiments show that the catalyst has a good performance on pyrolysis of waste polystyrene. The effect of pyrolysis temperature on catalyst activity and products composition is also discussed. |
