Implication

Research shows catalytic pyrolysis yields 70% liquid fuel from polyethylene waste, indicating improved efficiency over thermal methods.

Key Points

  • The catalytic method produced a 70% liquid fraction compared to 60% from the non-catalytic method.
  • GC-MS analysis revealed that catalytic products contain liquid compounds comparable to diesel, specifically in the C10 to C15 range.
  • The char from catalytic pyrolysis showed better porosity, suggesting enhanced properties for potential applications.
  • XRD analysis confirmed the presence of magnesium oxide within the activated char, pointing to possibilities for catalyst recovery.
