This research work includes the effect of Zeolite-A catalyst on the thermal degradation behavior of six different consumer plastic wastes like high density polyethylene (HDPE), polypropylene (PP), polyethylene terephthalate (PET), polymethylene methacralate (PMMA), polystyrene (PS) and polytetrafluoro ethylene (PTFE) through kinetic approach by using thermogravimetric analysis (TGA) data. Kinetic parameters such as reaction order, activation energy, and Arrhenius constant for the degradation of different waste plastics is determined using model fitting Coats–Redfern method. All the plastics show one-step degradation in the temperature range of 300–600°C. There is a significant decrease in activation energy (E_a) for the thermo-catalytic decomposition of the plastics in presence of Zeolite A catalyst. The extent of catalytic effect is found different for different plastics in the order of HDPE < PP < PS < PET < PMMA < PTFE. The order of the thermal degradation reaction is also found different for different types of plastics. The order of the reaction is altered in case of PET, PS and PTFE in presence of the catalyst but it is unaffected in case of remaining plastics. This treatment would reduce the energy consumption of pyrolysis process and also make the process economical viable.

这项研究工作包括Zeolite-A催化剂对六种不同消费塑料废料（如高密度聚乙烯（HDPE），聚丙烯（PP），聚对苯二甲酸乙二醇酯（PET），聚甲基丙烯酸甲酯（PMMA），聚苯乙烯（PS））的热降解行为的影响。 ）和聚四氟乙烯（PTFE）通过动力学方法使用热重分析（TGA）数据。使用模型拟合Coats–Redfern方法确定降解不同废塑料的动力学参数，例如反应顺序，活化能和Arrhenius常数。在300–600°C的温度范围内，所有塑料都会显示出一步降解的趋势。活化能（E _a）用于在沸石A催化剂存在下对塑料进行热催化分解。对于不同的塑料，发现催化作用的程度是不同的，依次为HDPE <PP <PS <PET <PMMA <PTFE。对于不同类型的塑料，热降解反应的顺序也不同。在有催化剂的情况下，在PET，PS和PTFE的情况下，反应顺序会发生变化，但在剩余塑料的情况下，反应顺序不会受到影响。这种处理将减少热解过程的能量消耗，并使该过程在经济上可行。
