Green energy production: hydroprocessing of waste plastic to diesel fuel using bimetal of Mn/Zn supported on activated carbon.

ABSTRACT: This research introduces a Mn/Zn-activated carbon (AC) bimetallic catalyst for hydroprocessing polypropylene pyrolysis oil (PPO) into hydroprocessed polypropylene pyrolysis oil blend (HPPO-B), which closely mimics commercial diesel. Under optimized conditions (70 bar, 350 °C), the catalyst efficiently converts PPO into iso-alkanes, n-alkanes, and aromatics, achieving a 95% compositional match with diesel. HPPO-B meets European EN590 diesel standards, with viscosity (3.9 mm² s^-1), density (855 kg m^-3), and cetane index (64), ensuring compatibility with diesel engines. Combustion tests show HPPO-B exhibits peak pressure and heat release rates within 96% and 95% of diesel values, respectively. Emission analysis reveals slightly higher CO (4-9 ppm) and C
