| Title: | Heterogeneous alkaline earth metal-transition metal bimetallic catalysts for synthesis of biodiesel from low grade unrefined feedstock | Authors: | Kwong, TL Yung, KF |
Issue Date: | 2015 | Source: | RSC advances, 2015, v. 5, no. 102, p. 83748-83756 | Abstract: | A bimetallic alkaline earth metal-transition metal oxide, synthesized through a method of direct low-temperature decomposition of the bimetallic complex, is reported for the synthesis of biodiesel. Due to the high phase purity of the Ca/Fe catalytic system and its catalytic stability and robustness, the Ca/Fe catalyst was selected for further investigation. A transesterification conversion of 99.5% could be achieved in 1 h under the optimal conditions: feedstock to methanol, 1:20; catalyst loading, 6 wt%; temperature, 120 °C. ANOVA tests suggested that the reaction temperature was discerned as the most prominent factor which contributed 82.84% to the overall catalytic feedstock conversion. In addition, the Ca/Fe catalytic system demonstrated a high FFA tolerance of 2 wt% and a water tolerance of 1 wt% with remarkable catalytic activity in one-step biodiesel synthesis. | Publisher: | Royal Society of Chemistry | Journal: | RSC advances | EISSN: | 2046-2069 | DOI: | 10.1039/c5ra13819a | Rights: | This journal is © The Royal Society of Chemistry 2015 The following publication Kwong, T.
