英文摘要As a new mineral carbonation process for co(2) sequestration, electrolysis of nacl solution and serpentine as the source of me(2+) to adsorb co(2) in the simulating flue gas is introduced, which used the electrolyze nacl solution to produce the hcl solution and naoh solution. the hcl solution was used to dissolve me(2+) from serpentine, and the naoh solution was used to adsorb co(2) in simulation smoke, then these two solutions were mixed to form mgco(3) deposition at 358 k, which could be processed at relative low temperature and pressure. in order to further increase the solubility of me(2+) from serpentine, the heat pretreatment of serpentine under nitrogen was investigated. the results indicated that the heat activation dramatically enhanced serpentine carbonation. xrd, tga, ft-ir and icp-aes analyses indicated that the best activation temperature was 650 degrees c, at which the crystalline features were changed from lizardite to amorphous followed the decomposition of hydroxyl groups. the dissolved capacity decreased with further increasing heat activation temperature, which might be related to the formation of a new crystalline feature. the xrd and tga analyses showed that the solid product was mainly pure basic magnesium carbonate.
