Nickel Catalysts Supported on Coal for Steam Reforming of Ethyl Acetate |
| 초록 |
Ethyl acetate is a volatile organic compound (VOC) that has emerged as a major environmental pollutant. In this study, fine Ni particles (size: ＜10 nm) were dispersed on low-rank coal (LRC) by the ion-exchange process. Catalytic steam reforming of ethyl acetate (EA) was performed over Ni supported on Eco LRC (Ni/Eco) to reduce emissions and simultaneously produce H2. EA reforming over Ni/Eco at 400 °C is comparable to that achieved with reforming over commercial Ni/Al2O3. Advantageously, metallic Ni particles are dispersed on LRC, and therefore, the pre-reduction step routinely required for an alumina-supported catalyst can be skipped. Furthermore, deactivation by coking is slower with Ni/Eco than with Ni/Al2O3 during long-term operation, probably because of the smaller particle size and preferential adsorption on the coal support. Instrumental analysis such as XRD, TGA, SEM, TEM, BET, and XPS has been done; the results provided clear understanding of the chemical and structural characteristics of coal-supported catalysts. |
