High Active Cu/SiO_2 Catalyst Prepared by Hydrolysis-Polymerization Method for 2-Butanol Dehydrogenation

摘要

Cu/SiO_2 catalyst by using Na_2SiO_3 as the silicon source, and the catalytic activity for 2-butanol dehydrogenation was compared with the conventional traditional industrial catalysts (Cu/Al and Cu/Zn). The catalysts were characterized by FTIR and XRD. The copper hydrosilicate was detected as the main phase in the dried sample. Cu_2O was detected in reduced sample, and can effectively prevent Cu~0 to forming big size particle. The Cu/SiO_2 catalyst compared with Cu/Al and Cu/Zn presented a much higher activity and stability in 2-butanol dehydrogenation process.
