Abstract  

Methanol dehydrogenation over CU/SiO2 prepared by different method was investigated in a fixed-bed reactor TPR was used to characterize the reduction property of the catalysts. Experimental results showed that catalysts with different initial structure exhibited different catalytic behavior in methanol dshydrogenation. With the reaction going on the activity and selecivity of methyl formate and CO decreased and the selectivity of formaldehyde increased due to the sintering and carbon deposition on the surface.



Key wordsCu/SiO2 catalysts      Methanol      Dehydrogenation      Catalytic properties
