- Abstract
- With growing levels of CO2 emission and severity of global warming, interest in carbon capture and utilization (CCU) has increased. However, the amount of CO2 reduction that can be realized is lower than that of CO2 emissions, and most of the existing CCU technologies cannot be commercialized owing to their limited economic feasibility. Therefore, it is necessary to identify new chemicals as CCU products. When CaO is added to a formate aqueous solution, it reacts with the formate to produce calcium formate (Ca(HCO2)2). In this study, Ca(HCO2)2 was synthesized using dolomite and CaO ash, an industrial waste. Process design and evaluation were performed based on the experimental data. When CaO ash and dolomite were used as the raw material, the production costs were 16% lower and 8% higher than those of the conventional process, respectively. Moreover, for both materials, the CO2 emissions were 20% lower than those of the conventional processes. © 2023 Elsevier B.V.
