| 摘 要： | 采用盐酸和氢氧化钾对膨润土(BEN)进行改性处理,通过浸渍法制备了改性后膨润土负载的镍催化剂,并对其在二氧化碳甲烷化过程中的催化性能进行了研究.借助BET、XRD、TPR和TPD等测试技术对催化剂进行了表征.结果表明,用碱处理后的膨润土比表面积小于酸处理膨润土的,但以碱处理的膨润土为载体所制备的镍催化剂(Ni/alka...

| Abstract: | HCl and KOH were used to modify bentonite(BEN).The Ni catalysts supported on acidified and alkalified bentonite had been prepared by aqueous impregnation.Methanation of carbon dioxide was used as a probe reaction to characterize the catalytic performance.The samples were characterized by BET,XRD,TPR and TPD.The results showed that a higher catalyst activity was achieved for Ni/alkali-BEN,although the alkali-BEN had lower surface area.CO2-TPD and H2-TPR study showed that Ni/alkali-BEN could absorb more carbo... |
