Dehydrogenation of ethane and subsequent CO2 activation on iron impregnated ordered mesoporous TiO2 for chemical looping application |
| 초록 |
Chemical looping process using redox catalysts has been interested to selectively produce C2H4 by dehydration of C2H6 and greenhouse gas of CO2 activation to CO. The reduction reaction on the iron-loaded mesoporous TiO2 with 5 to 20 wt%Fe using C2H6 selectively produced C2H4, and the catalyst also subsequently activated CO2 to CO by oxidation reaction. The catalyst was prepared by impregnation method of iron precursor on the mesoporous TiO2. A maximum 88% selectivity of C2H4 with 15% conversion of C2H6 was obtained on 15wt%Fe/TiO2 at 600 oC, and CO2 conversion of 7.9% was separately obtained on the same catalyst at 700 oC through facile redox reactions of active metals. The structural properties of Fe/TiO2 were characterized by N2 sorption, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) and so on. |
