Abstract: |
Carbon capture and utilization (CCU) represent a promising strategy to reduce CO2 emissions and promote a sustainable economy. We report an integrated CCU (ICCU) process by integrating CO2 capture with reverse water gas shift reaction by applying simple and low-cost CaO as both sorbent and catalyst. By switching the feeding gas from CO2 source to H2 isothermally, up to 75% of captured CO2 was 100% converted into CO at 600-700 °C and the cycle performance of CaO was significantly improved under ICCU condition. In addition, the simulation confirms the significant economic advantage compared to similar traditional processes. The work could dramatically reduce the cost of materials and simplify CCU processes to advance the development and deployment of carbon neutrality technologies.One-Sentence Summary: A low-cost and widely used material, CaO, was used to not only adsorb CO2 efficiently but also in situ convert CO2 into valuable syngas with > 75% CO2 conversion to realise carbon neutrality, which is a vital target for sustainable future development. |
