Ethanol synthesis from syngas over Cu/Zn/Al-B catalysts: The promoting effect of boron
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%). Th...

Summary: | 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 Cu
