Synthesis of Highly Ordered Mesoporous Metal Oxides as Solid Acid Catalysts for Glycerol Acetalization to Fuel Additives |
| 초록 |
Glycerol is produced at a large amount as a 10% by-product from biodiesel production. Therefore the development of new outlets from waste glycerol to value-added chemicals is of importance to enhance the economic profitability of biodiesel. In the present work, acetalization of glycerol has been carried out using ordered mesoporous metal oxides such as meso-MoO2, meso-WO3, meso-SnO2, meso-Co3O4 as a solid acid catalyst. The materials were characterized by X-ray diffraction, N2–sorption, Scanning electron microscope and Transmission electron microscopy. Among the catalysts, the meso-MoO2 catalyst showed highest activity than the other meso-MOx due to the presence of a large amount of acidic sites. The most excellent conversion of glycerol (96%) was obtained in 1h at 20℃ with 98% selectivity for solketal using meso-MoO2. Also, the meso-MoO2 catalyst was stable and reusable in most cases. These results indicate the potential of this catalyst for an environmentally benign process. |
