Example Embodiment
[0028] Implementation example 1
[0029] The mineralization process of this embodiment is as attached figure 1 Shown. The electrolyzer is divided into positive electrode area, middle area and negative electrode area by a cation exchange membrane 2 that only allows cations to pass through but can prevent anions from passing through, and an anion exchange membrane 3 that only allows anions to pass through but can prevent cations from passing through. area. Add 2mol / L of H 2 SO 4 The solution is put into the positive electrode electrolyzer as the positive electrode electrolyte, adding 1.2mol / L MgCl 2 The solution is transferred to the negative electrode electrolyzer as the negative electrode electrolyte, and 0.4 mol / L hydrochloric acid is added to the intermediate chamber. The gas diffusion electrode 1 is used as the positive electrode, and the platinum electrode 4 is used as the negative electrode. CO bubbling at the bottom of the negative electrode electrolyzer 2 The flow rate i...

[0030] Implementation example 2
[0031] The mineralization process of this embodiment is as attached figure 2 Shown. The electrolytic cell is divided into positive and negative regions by an anion exchange membrane 3 that allows only anions to pass through but can prevent cations from passing through. Add 2 mol / L HCl solution to the positive electrode electrolyzer as the positive electrode electrolyte, and add 2 mol / L MgCl2 solution to the negative electrode electrolyzer as the negative electrode electrolyte. The metal titanium iridium electrode 6 is used as the positive electrode, and the metal nickel electrode 4 is used as the negative electrode. CO bubbling at the bottom of the negative electrode electrolyzer 2 The flow rate is 20 ml / min, and the electrolysis reaction is carried out at a voltage of 2.6 V for 1 h. Heat the liquid in the negative electrolytic cell to obtain CO 2 The mineralization product of basic magnesium carbonate solid. The current efficiency for produ...
