| 摘 要： | 采用共沉淀法合成水滑石,等体积浸渍法将碳酸钾负载于水滑石孔道及层状结构中;在一定空速条件下,考察了吸附温度、碳酸钾添加量、活化温度对碳酸钾修饰水滑石吸附二氧化碳性能的影响;利用SEM、BET等手段对修饰后的水滑石进行了表征。在一定实验条件下,水滑石吸附容量可以达到9.10mol/kg。

| Abstract: | This paper adopted co-precipitation method to synthesize LDH,and volumetric immersion method was also used to load potassium carbonate into the pore water and the layered structure of talc.The author investigated adsorption temperature,adding amount of potassium carbonate,and the influence of activation temperature on potassium carbonate modification on the adsorption of carbon dioxide,under certain space velocity condition.Furthermore,SEM,BET and other means were performed to characterize the hydrotalcites after treated;the adsorption capacity of hydrotalcite was up to 9.10mol/kg at a given set of experimental conditions. |
