在这个工作,在用离子交换膜电解的 CO2 的吸收以后的钾碳酸盐答案的新生机制被介绍。钾碳酸盐(K2CO3 ) 和钾酸式碳酸盐(KHCO3 ) 的答案被用来在吸收 CO2 以后模仿答案。实验在各种各样的电极,温度和当前的密度被执行。结果显示膜电解能增加 K2CO3 和 KHCO3 的集中比率,并且完成 100% 变换。在这,过程,不是仅仅 CO2 从碳酸盐答案被使放出,而且作为一个副产品,氢在阴极被产生,它是主要贡献者减少精力消费。因此,膜电解在 K2CO3 吸收剂的新生是珍贵的。
In this work,the regeneration mechanism of potassium carbonate solution after absorption of CO2 using ion-exchange membrane electrolysis was presented.The solutions of potassium carbonate(K2CO3) and potassium bicarbonate(KHCO3) were used to simulate the solution after absorbing CO2.Experiments were carried out at various electrodes,temperatures and current densities.The results indicate that the membrane electrolysis can in-crease concentration ratio of K2CO3 and KHCO3,and achieve 100%conversion.In this process,not only CO2 is desorbed from carbonate solution,but also hydrogen,as a byproduct,is generated at the cathode,which is the main contributor to reduce energy consumption.Thus,the membrane electrolysis is valuable in the regeneration of the K2CO3 absorbent.
