摘要：
Ethanol synthesis from syngas was studied over Cu/Zn/Al catalysts promoted with different B contents using the complete liquid-phase technology. It is found that ethanol selectivity is strongly influenced by B content. When the B content is 6.0 wt%, the ethanol selectivity is the highest (37.6%). The characterization results indicated that a suitable B promoter prevents the growth of copper particles, strengthens the interaction between Cu and Al or Zn species, increases the relative amount of Cu2O on the catalysts surface, and keeps the balance of Cu+-Cu degrees.
