Catalytic co-pyrolysis of biomass and plastics (HDPE (high density polyethylene), PP (polypropylene) and
PET (polyethylene terephthalate)) has been performed in a fixed-bed reactor in presence of cobalt based
alumina, ceria and ceria-alumina catalysts to analyze the product distribution and selectivity. Catalysts
are synthesized using co-precipitation method and characterized by BET (BrunauereEmmetteTeller)
surface area and XRD analysis. The effect of catalytic co-pyrolysis at different temperature with product
distribution has been evaluated. The results have clearly shown the synergistic effect between biomass
and plastics, the liquid products gradually increases forming with rise in the plastic content in the blend.
Gaseous products have yielded most during pyrolysis of blend having biomass/plastics ratio of 5:1 with
the presence of 40% Co/30% CeO2/30% Al2O3 catalyst with hydrogen gas production touched its peak of
47 vol%. Catalytic performance enhanced with increase with the cobalt loading, with best performance
attributing to 40% Co/30% CeO2/30% Al2O3 catalyst.
