CO₂ Capture-Mineralization for Calcium-Looping Integrated with Methane Dry Reforming.

ABSTRACT: Chemical absorption of carbon dioxide using monoethanolamine (MEA) is a well-established method for postcombustion CO₂ capture. In this study, we aimed to integrate (1) the MEA-based CO₂ capture with the regeneration of MEA using calcium-based mineralization, followed by (2) direct utilization of captured CO₂ to form syngas via a calcium looping-based dry reforming of methane (CaL-DRM), an interfacial catalytic process. The results show that room-temperature CO₂ capture-MEA regeneration was achievable by using calcium-based mineralization. The formed Ni-Ca material was shown to be active for converting the captured CO₂ into syngas via the CaL-DRM reaction at 600 °C. A 10-cycle stability test confirmed the operational stability of the N
