| description | Abstract The high energy consumption of Carbon Capture Utilization and Storage(CCUS) promotes the research of integrated absorption and mineralization technology. A novel DEEA/AEP biphasic absorbent is used to absorb $$\hbox {CO}_{2}$$ . After phase separation, only one phase enriched with the absorption product is sent into the mineralization system, then reacts with $$\hbox {Ca(OH)}_{2}$$ to produce $$\hbox {CaCO}_{3}$$ at normal temperature and pressure. The effects of temperature, Ca/C and dispersion of the system were investigated, and cyclic utilization experiment was also conducted. The process was characterized and analyzed by Thermal gravimetric analysis (TGA), X-ray diffraction (XRD), and nuclear magnetic resonance (13C NMR). The results showed that at 50 $$^{\circ }$$ C, Ca/C = 1, the extent of mineralization of $$\hbox {CO}_{2}$$ -enriched phase mineralization was 95.73% after ultrasonic treatment for 30 min. During 6 cycles, the volume percentage of $$\hbox {CO}_{2}$$ -enriched phase could be maintained at 52–55%, and the $$\hbox {CO}_{2}$$ load was 11.92mol/L. The results above indicate that the $$\hbox {CO}_{2}$$ -enriched phase mineralization technology after absorption by biphasic absorbent can effectively capture $$\hbox {CO}_{2}$$ , realize recycling, and reduce CCUS energy consumption. |
