| Abstract: | The Cu Zn Al catalyst for methanol synthesis were prepared by the high speed collision coprecipitation method.Although the Cu contents of both the Cu Zn Al and ICI 51-2 catalysts are similar, the dispersion of the former is 37.5% higher than that of the latter. Activity of the Cu Zn Al catalyst for methanol synthesis is 40% higher than that of ICI 51-2 when operated at 2.0 MPa, 210℃ and a space velocity 3600 h -1 . FTIR spectra suggests that formate acid is the intermediate in methanol synthesis and Cu + is the active surface state. |
