Carbon complex supported nano-catalysts for gas-to-liquids |
| 초록 |
A hexagonally ordered mesoporous carbon (OMC) and other materials were utilized as supports for Fischer-Tropsch catalysts. Each array of elongated pore structure with metal nanoparticles can be regarded as a nanochannel reactor. Due to the pore confinement and the hydrophobic nature of the OMC, this catalyst demonstrated the excellent catalytic performance for synthetic fuels. Regarding non-porous carbon sphere supported Rh catalyst, FT-IR spectroscopy of adsorbed CO has revealed the presence of linearly bonded CO at Rh0 sites and gem dicarbonyl species at Rh+ sites, which are crucial to chain growth and oxygenate formation, in promoted Rh catalysts encapsulated in carbon spheres. Although syngas-to-alcohols technology has focused primarily on production of ethanol, this study has shown that carbon spheres and ordered mesoporous carbon supports enhance CO adsorption and selective production of C3 and C4 alcohols as well as ethanol. |
