| 摘 要： | 采用低温氮气吸脱附、X射线衍射(XRD)、电镜(TEM)以及热重差热(TG-DSC)等手段,对不同反应时间下Cu/ZrO2催化剂的物理结构、微观形貌以及积炭情况进行了表征,分析了催化剂的失活原因。结果表明,造成催化剂失活的主要因素是活性组分烧结;其次,表面积炭覆盖其活性中心也造成催化剂活性在一定程度上的降低;而催化剂比表面积对其活性的影响较小。

| Abstract: | The physical structure, microstructure and carbonaceous deposition of Cu/ZrO2 catalysts for methanol synthesis from CO2 hydrogenation were characterized by nitrogen sorption, X-ray diffraction (XRD), transmission electron microscope (TEM), and thermogravimetry and differential scanning calorimetry (TG-DSC) techniques. The results showed that the sintering of active components is the major factor for catalyst deactivation and the carbonaceous deposition is in the next place; the surface area has little effect on catalyst activation. |
