| Summary: | Catalytic co-pyrolysis of waste cotton fabric and polypropylene (PP) plastic at different temperatures and durations in a fixed bed reactor was carried out. Various Cr-Al catalyst loading that prepared via wet impregnation method were used. The gas, liquid and char product were analyzed to investigate its influence towards temperature and pyrolysis duration. A mixed trend of product yield was observed as temperature increases. At lower temperature (300°C), gaseous component dominates the overall product yield. However, liquid product as the desired component increased significantly and peaked (40.6 wt%) at 600°C. The highest liquid product yield in terms of quantity was achieved during 30 minutes of pyrolysis, whereas the best product quality was achieved for 60 minutes. Therefore, pyrolysis at 600°C for 60 minutes using 20% Cr-Al catalyst loading was the optimal condition for the catalytic co-pyrolysis of waste cotton fabric and PP. © 2024 American Institute of Physics Inc..
