- 化学化工－已发表论文 
用高速碰撞共沉淀法制备的Cu-zn-Al甲醇合成催化剂，其含Cu量与ICI51-2相近，但分散度比ICI51-2高37.3%。在2.067MPA、210℃、3600H-1反应条件下，其甲醇合成活性比ICI51-2高40%，fTIr实验表明，反应中间态是甲酸盐，Cu＋是活性表面物种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.
