| 摘 要： | 实验以CS2为硫源,考察硫对完全液相法制备Cu-Zn-Al催化剂活性的影响,并用X射线粉末衍射(XRD)、氢气程序升温吸附(H2-TPR)、氨气程序升温脱附(NH3-TPD)等方法对催化剂性能进行了表征。结果表明,对完全液相法制备的Cu-Zn-Al催化剂而言,加入小于4mg/L 的CS2对催化剂的活性影响不大;催化剂的活性随着加入硫含量的增加,下降程度增大。

| Abstract: | This article reports the study on the effects of CS2 exposure on the Cu-Zn-Al slurry catalysts prepared by a complete liquid phase technology and characterized by X-ray diffraction(XRD),H2-TPR,and NH3-TPD.For the Cu-Zn-Al catalyst prepared by complete liquid-phase technology,low-level sulfur addition(<4 mg/L)did not significantly influence the conversion of CO.But the addition of a higher-level loading of sulfur(>100 mg/L)resulted in severe sulfur poisoning of the catalysts. |
