Mixed metal oxides for oxidative dehydrogenation of ethane and CO2 activation by a cyclic redox reaction |
| 초록 |
An alternative route of oxidative dehydrogenation of ethane (CL-ODH) by chemical looping process with transition mixed metal oxides was investigated by a cyclic redox reaction, which was designed to convert ethane into ethylene by reduction step on the mixed metal oxides and subsequent CO2 activation to CO by oxidation step on the partially reduced metal oxides. A prototype Fe/TiO2 with 5wt%Fe exhibited a higher ethane conversion of 9.7% and ethylene selectivity of 91% by showing a volcano-plot in terms of Fe content between 5~20wt%Fe. In addition, Ce-incorporated FeTiOx with 5wt%Fe showed a further enhanced ethane conversion for CL-ODH. The reducibility of the mixed metal oxides was clearly related with the catalytic performance by increasing the Fe2+ content as well as oxygen vacant sites through a facile redox properties of mixed metal oxides. |
