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

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.
