Description
Summary:The suppression of greenhouse gas emissions is being considered more important than ever, and consequently, the development of methods to produce useful CO2 conversion products with excellent techno-economic feasibility and high CO2 reduction capability is of interest. A continuous CO2 conversion system and a heterogenized hydrogenation catalyst can be used to develop a process for the efficient and selective production of Ca(HCO2)2, which has not been considered as a CO2 conversion product so far, from waste resources, including CaO. Techno-economic analysis of the entire process showed that the production cost of Ca(HCO2)2 was reduced by around 16% compared with the conventional process, indicating a high possibility of market penetration. Furthermore, the estimation of the global warming index of the process through a life-cycle assessment showed that the global warming index could be reduced by about 20% compared with that of existing Ca(HCO2)2 production processes.
