Abstract

The globally plastic produced expanded over years because of the variety applications of plastics in various sectors that caused the accumulation of waste plastic in the landfill. The growth rate of plastic demand obviously affected the resources of petrolium availability as non-renewable fossil fuel since plastics were the petroleum-based material. some options that have been considered for waste plastic management were recycling and energy recovery methods.The present work involves the comparative study of catalytic pyrolysis of waste polypropylene (PP) using various type of catalyst such as silica alumina, kaolin clay and calcium bentonite. The effect of silica alumina, which has been extensively studied by different investigators for the pyrolysis of waste polypropylene and compared with that of catalytic performance of kaolin and calcium bentonite. from the study it is found that silica alumina is found to be best as a catalyst for the degradation of plastics waste to liquid fuel and valuable chemicals and also improved the yield fraction and reaction time. From the optimization study it is found that, the maximum oil yield in thermal pyrolysis of polypropylene waste was 84 wt% at 500°C.and the maximum oil yield in catalytic pyrolysis with using silica alumina was 91 wt% at 500°C with feed ratio of plastic to catalyst 3:1. The rate of reaction, oil yield and quality of oil obtained in the catalytic pyrolysis using silica alumina catalysts are significantly improved compared to the thermal pyrolysis and catalytic pyrolysis using kaolin and calcium bentonite catalyst. The fuel properties of the produced oil with the help of catalytic pyrolysis of polypropylene are same as that of petro-fuels. Therefore, they can be used directly as an fuel after fractionation of liquid.
