| Abstract: | In this paper,the influence of different mole ratio of Cu/Mn,Al 2O 3 content,calcination temperature and reaction temperature on the hydrogenation activity of carbon dioxide over Cu-MnO x/Al 2O 3 catalysts has been studied The changes of the Cu/Mn mole ratio,the content of Al 2O 3,calcination and reaction temperature are found to be very significant for the catalytic activity.Good catalytic activity and good methanol selectivity can be obtained when n(Cu)∶n(Mn)=12,Al 2O 3 content in catalyst is 5%～10%,and calcination temperature is 400 ℃ |
