AB  - With ever-increasing plastic waste, a robust and sustainable methodology to 
      valorize the waste and tweak, the composition of the value added product is the 
      need of the hour. The present study describes the effect of different 
      heterogeneous catalyst systems on the yield, composition and nature of the 
      pyrolysis oil produced from various waste polyolefins like high-density 
      polyethylene (HDPE), linear low-density polyethylene (LLDPE), and polypropylene 
      (PP). The waste polyolefins were subjected to thermal as well as catalytic 
      pyrolysis. Liquid, gas, and solid products were obtained during the pyrolysis. 
      Various catalysts such as activated alumina (AAL), ZSM-5, FCC catalyst, and 
      halloysite clay (HNT) were used. Usage of catalysts has reduced the temperature 
      of the pyrolysis reaction from 470 to 450  degrees C with better liquid product yield. PP 
      waste generated higher liquid yield compared to LLDPE and HDPE waste. The highest 
      liquid yield of 70.0% was achieved with PP waste using AAL catalyst at 450  degrees C. 
      The sulfur and chloride content was found to be < 10 and < 20 ppm respectively in 
      all the pyrolysis liquid. Pyrolysis liquid products were analyzed using gas 
      chromatography (GC), nuclear magnetic resonance (NMR) spectroscopy, 
      Fourier-transform infrared (FTIR) spectroscopy, X-ray fluorescence (XRF) 
      spectroscopy, and gas chromatography coupled with mass spectrophotometry (GC-MS). 
      The obtained liquid products consist of paraffin, naphthene, olefin and aromatic 
      components. Catalyst regeneration experiments with AAL showed that the product 
      distribution profile remains the same up to three cycles of regeneration.
