Effect of Co dispersion on the catalytic properties of Co/Al2O3 in Fischer-Tropsch synthesis |
| 초록 |
The Fischer-Tropsch (FT) synthesis on cobalt-based catalysts has been a promising route to synthesize clean and environmentally benign fuels. Alumina is one of the most employed supports for cobalt FT catalysts due to its favorable mechanical properties and adjustable surface properties. The present study focuses on the development of simple dispersion method of cobalt on Al2O3 by changing the pH of solution during the catalyst preparation, and correlating cobalt particle size with the activity. Our results suggest that the control of cobalt particle sizes during preparation of catalysts plays an important role in the catalytic properties on FT reaction. The activity and selectivity of FTS depend on the reducibility of cobalt particles with different size. The increase of C5+ selectivity is found on the catalyst with larger cobalt particles, which are easily reduced at much lower temperature. This would be mainly due to easy readsoprion of formed molecules on larger cobalt particles. |
