Summary, etc. |
A<strong> </strong>Nano-alumina-zirconia composite catalyst was synthesized by a simple aqueous sol-gel method using AlCl<sub>3</sub>.6H<sub>2</sub>O and ZrCl<sub>4</sub> as precursors. Thermal decomposition of the precursor and subsequent formation of γ-Al<sub>2</sub>O<sub>3</sub> and t-ZrO<sub>2</sub> were investigated by thermal analysis. XRD analysis showed that γ-Al<sub>2</sub>O<sub>3</sub> and t-ZrO<sub>2 </sub>phases were formed at 700 °C. FT-IR analysis also indicated the phase transition to γ-Al<sub>2</sub>O<sub>3</sub> occurred in corroboration with X-ray studies. TEM analysis of the calcined powder revealed that spherical particles were in the range of 8-12 nm. The nano alumina-zirconia composite particles were mesoporous and uniformly distributed in their crystalline phase. In order to measure the catalytic activity, esterification reaction was carried out. Biodiesel, as a renewable fuel, was formed in a continuous packed column reactor. Free fatty acid (FFA) was esterified with ethanol in a heterogeneous catalytic reactor. It was found that the synthesized γ-Al<sub>2</sub>O<sub>3</sub>/ZrO<sub>2</sub> composite had the potential to be used as a heterogeneous base catalyst for biodiesel production processes. |
