The Influence of Pyrolysis Time and Temperature on the Composition and Properties of Bio-Oil Prepared from Tanjong Leaves (Mimusops elengi)

This research aims to evaluate the influence of pyrolysis time and temperature on composition properties bio-oil derived from Mimusops elengi. Experiments were conducted by varying 400 600 °C 30 120 min, respectively. Both found significantly composition. At enhanced temperatures, yield increased while ash gas yields decreased. In addition, extended produced a greater yield, indicating that higher temperatures longer durations promote additional decomposition biomass. Functional groupings, including alcohols, phenols, ketones, esters, aromatic compounds in bio-oil, identified via FT-IR analysis, bio-oil’s diversified chemical make it potential alternative feedstock. GC-MS analysis 26 which phenol was most abundant. However, high content can diminish quality enhancing acidity, decreasing heating value, encouraging engine corrosion. Temperature are crucial factors producing with desired physical properties. The maximum 34.13%, attained after 90 min operation at 500 °C. characteristics elengi produced, namely density, viscosity, pH, HHV 1.15 g/cm3, 1.60 cSt, 4.41, 19.91 MJ/kg, respectively, accordance ASTM D7544. Using as feedstock demonstrates its an environmentally friendly energy source for variety industrial environmental applications. is not optimal due formation tar, results blockage output flow during process.
