Experimental study on the cyclic mineralization of CO₂ enriched phase after absorption by a novel biphasic absorbent composed of DEEA and AEP.

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 [Formula: see text]. After phase separation, only one phase enriched with the absorption product is sent into the mineralization system, then reacts with [Formula: see text] to produce [Formula: see text] 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 [Formula: see text]C, Ca/C
