Techno-economical and energy analysis of sunflower oil biodiesel synthesis assisted with waste ginger leaves derived catalysts

Abstract The present study was carried out to investigate biodiesel production via transesterification of sunflower oil employing heterogeneous catalyst derived from indigenous ginger (Zingiber Officinale) leaves. It also aims compare the techno-economy performance ginger-based catalysts in 3 different forms viz. calcinated (CGL), activated by KOH (KGL) and NaOH (NGL). plant-based were characterised Scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) Fourier transform infrared spectroscopy (FTIR). parametric effects on such as reaction time, methanol ratio loading investigated. experimental result shows that 1.6 wt % catalyst, 6:1 M alcohol oil, 1 h 30 min time with a speed 200 rpm gave best results. found KGL obtained highest yield 93.83% under optimum conditions. Subsequently, specific energy productivity be 1.2728, 26.1544 MJ/kg 0.0382 kg/MJ, respectively, per 1 L biodiesel. Meanwhile, renewable non-renewable for CGL, NGL is 3.17, 4.01 3.67, respectively. A higher sustainable energy-yield overall economical profit cost are preferable process.
