چکیده انگلیسی
An attempt has been made to optimize biodiesel production from Bombax ceiba oil (BCO) through calcium oxide nanoparticles (CaO-NPs) catalyzed transesterification. Characterization of CaO-NPs synthesised by solution combustion method was carried out using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), Brunauer-Emmett Teller (BET) and Thermogravimetric analysis (TGA). The influence of reaction parameters was studied and optimized by using Response Surface Methodology (RSM) in combination with central composite design (CCD). Two-stage transesterification technique was employed for biodiesel production and 96.2% yield of Bombax ceiba methyl ester (BCME) was achieved under optimum conditions. The CaO-NPs were reused up to 5 cycles with appreciable loss of yield. From the kinetic study performed at different reaction temperatures (55 °C, 60 °C and 65 °C) Ea = 35.99 kJ/mol was obtained. Fuel properties of produced methyl ester were also determined and compared with ASTM standards for biodiesel.
