主　　题：membrane electrolysis Benfield regeneration carbon dioxide 

摘      要：In this work,the regeneration mechanism of potassium carbonate solution after absorption of CO2 using ion-exchange membrane electrolysis was *** solutions of potassium carbonate(K2CO3) and potassium bicarbonate(KHCO3) were used to simulate the solution after absorbing *** were carried out at various electrodes,temperatures and current *** results indicate that the membrane electrolysis can in-crease concentration ratio of K2CO3 and KHCO3,and achieve 100%*** 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 ***,the membrane electrolysis is valuable in the regeneration of the K2CO3 absorbent.
