Abstract:
The present study investigates the performance of a homogeneous Cd-Mncatalyst in the cleaner production of biodiesel from the novel non-edible seed oilof Prunus cerasoides D. Don., containing 51.8% oil and a free fatty acid (FFA)content of 0.52 mg KOH/g. The catalyst was characterized using X-rayDiffraction (XRD), Scanning Electron Microscopy (SEM), Energy DispersiveX-ray (EDX), and Fourier Transform Infrared Spectroscopy (FTIR).Underoptimized transesterification conditions- 4 h reaction time at 110 °C, a 10:1molar ratio of methanol to oil, and 3% catalyst loading-the process achievedthe highest fatty acid methyl ester (FAME) yield of 88%. The resulting biodieselwas further analyzed using FTIR, Gas Chromatography-Mass Spectroscopy(GC-MS), and Nuclear Magnetic Resonance (¹H, ¹³C NMR).Fuel properties ofthe synthesized biodiesel were determined as density (0.8654 kg/L), kinematicviscosity (4.36 mm²/s), flash point (78 °C), cloud point (-8 °C), and pour point(-11 °C). All measured values were in accordance with China’s GB/T 20828(2007), American (ASTM D6751, D951), and European (EN 14214) biodieselstandards.Kinetic analysis revealed that the transesterification reaction followeda pseudo-first-order model, with a correlation coefficient (R²) of 0.9285,indicating a good fit with the experimental data. These findings suggest that thehomogeneous Cd-Mn catalyst offers a cost-effective, stable, and highly efficientalternative for biodiesel synthesis, with strong potential for industrial application.
