Effects of CS₂ on the performance of Cu-Zn-Al catalyst prepared for DME synthesis by complete liquid-phase technology

摘要

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(<4mg/L)did not significantly influence the conversion of CO. But the addition of a higher-level loading of sulfur(>100mg/L)resulted in severe sulfur poisoning of the catalysts.
