Influence of copper surface area of Cu/ZnO/Al2O3 on the catalytic performance in methanol, dimethyl etherand desulfuriztion reactions |
| 초록 |
The influence of metallic copper surface area of Cu/ZnO/Al2O3 was investigated in the synthesis of methanol and dimethyl ether (DME) from syngas, water-gas shift reaction and adsorptive desulfurization. The structural promoters such as ZnO and Al2O3 play significant roles in varying the dispersion of active copper species and result in altered catalytic performance. The nature of acidic component such as zeolite on DME synthesis from syngas significantly affects DME yield. In methanol synthesis, Ga (or Zr) addition on Cu/ZnO/Al2O3 enhances copper surface area by acting as structure promoters. The catalysts showing high activity on methanol synthesis also presents high activity on water-gas shift reaction. In addition, the concentration of structural promoter (Al2O3) in Cu/ZnO/Al2O3 is also optimized to obtain high copper surface area and high capacity in adsorptive desulfurization reaction. |
