| 摘 要： | 用热重分析方法研究了HY沸石与改性Y沸石(UHY)作为催化降解聚苯乙烯的催化剂对聚苯乙烯催化降解的作用及影响，对聚苯乙烯的催化降解与热降解反应产物进行了比较。结果表明，催化剂的存在能显著地降低聚苯乙烯的降解温度，催化剂的酸量和孔结构对聚苯乙烯的降解温度、活化能、积炭的生成量及裂解产物有很大的影响。

| Abstract: | Thermo-gravimetric analysis was used in the study on the catalytic degradation of polystyrene with HY zeolite and modified Y zeolite (UHY) as catalysts.The products of polystyrene catalytic degradation were compared with the products of polystyrene pyrolysis.The results show that catalyst can significantly decrease the degradation temperature of polystyrene,and the acid amount and porous structure of catalyst have important effects on degradation temperature and activation energy of polystyrene and coke yield. |
