电场力作用下支撑熔盐膜脱除CO2^＋

Study on the removal of CO_2 by Electrochemical Cell with Molten Carbonates as Electrolyte

摘要: 在改变电极面积的条件下，对影响ＣＯ２分离的各参数，如端电压，电流密度、ＣＯ２浓度等进行了测定，同时对电极制备过程与性能的关系也进行了探讨。结果表明，在实验条件范围内，ＣＯ２通量唯一与电流密度相关，且与电流密度成近似直线关系；增大电极面积有利于能耗的减小；泡沫镍电极在相同操作条件下电压比多孔镍电极降低１５％￣２０％。

Abstract: A new process to remove CO_2 from the atmosphere by a molten cabonate electro chemical cell was proposed.The effect of various parameters such as electric current and voltage on CO_2 flux had been studied in this work with different electrode areas,The results,showed that the CO_2 flux remained constant under the given experimental conditions with the change of elec trod ares.In addition,a new electrode was used in this work,which was of lower cost and higher permeability for CO_2 compared with the conventional electrode.
