Syngas transformations to clean fuels using mesoporous materials |
| 초록 |
The syntheses of valued-added chemicals from syngas were investigated using the ordered mesoporous metal oxides such as the cobalt or iron-based catalysts for CO hydrogenation to form paraffinic hydrocarbons (Fischer-Tropsch synthesis, FTS) and Cu supported on the M-modified mesoporous alumina (M = Zn, Ga) for DME synthesis form syngas. A higher catalytic activity and its stability on the mesoporous metal oxides were obtained by modifying them with optimal contents of structural promoters. For the FTS reaction, the mesoporous CoAlOx and FeZrOx catalysts showed a stable catalytic activity with higher C5+ hydrocarbon formation rate due to the preserved mesoporous structures. For the direct DME synthesis from syngas, the ordered mesoporous Cu/Ga-Al2O3 showed a slower deactivation phenomenon due to the phase transformations of the Ga2O3 modifier in the matrix of Al2O3 without any significant aggregations of copper nanoparticles. |
