Abstract
Mesoporous calcium titanate (MCT) catalyst was synthesized via a sol-gel-hydrothermal method and investigated as a catalyst for biodiesel production from waste cooking oil (WCO). Calcium was supported on titanate in order to increase their surface area, stability and consequently, improve its performance in the transesterification of WCO to biodiesel. Synthesized catalyst was characterized with powder X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), N2 physisorption, Fourier transform-infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA) and carbon dioxide temperature-programmed desorption (CO2-TPD). The catalyst possessed high surface area, basicity and stability than calcium oxide (CaO) catalyst. The highest biodiesel yield achieved was 80.0% in 3:1 of methanol to WCO molar ratio, 0.2 wt.% of MCT catalyst for 1 h at 65 °C. Reusability study suggested that this catalyst can be recycled for five successive runs.
