Abstract: A series of catalysts for methanol synthesis were prepared by vacuum freeze drying. Catalytic properties of catalysts were investigated with XRD,H2-TPR,CO2-TPD,TEM,EDAX,and BET and evaluation of catalytic activity was conducted in a micro fixed-bed reactor. The results showed that the catalysts for methanol synthesis prepared by vacuum freeze drying had high specific surface area,high activity and high selectivity.

Key words: methanol, carbon dioxide, catalyst, vacuum freeze drying, methanol, carbon dioxide, catalyst, vacuum freeze drying
