Abstract

Mineral carbonation‏ ‏is one of the typical carbon capture, utilization, and storage technologies, ‎to obtain synthetic carbonates from metal oxide and CO2. However, the technology is known ‎to be extremely challenging to achieve economic feasibility ‎because expensive chemical ‎solvents‏ ‏used the account for most of the cost. To overcome this ‎limitation, we conducted a ‎pilot laboratory study to secure the economic viability of the ‎technology by replacing these ‎chemical solvents with costless metallic carbon dioxide ‎cylinders. For the current study, we ‎implement cement kiln dust (CKD), which is an alkali industrial by-product, together ‎with‏ ‏mineral CO2 gas. In this research paper, we attained CO2 storage and CaCO3 yield, ‎which is comparable‏ ‏in both quantitative and qualitative respects to the existing studies. With ‎a steady flow rate of 0.9 L/m of carbon dioxide furthermore fixed time, the carbonation of ‎CKD could increase dramatically, reaching 35% calcium carbonate at 550°C and 27% calcium ‎carbonate at 450°C respectively. It was also found that CO2 flow rate is one component, ‎which can elute Ca from‏ ‏CKD, and had significant effects on carbonation ‎efficiency. The ‎solid to liquid ratio was the most influential factor in the Ca elution process.‎‏ ‏the ‎microstructure, morphology, and thermal traits of the designed patches are characterized ‎using scanning electron microscopy (SEM) to indicate phases composition, X-Ray Diffraction ‎‎(XRD), and Fourier-transform infrared spectroscopy (FTIR) measurements.‎
