Resumen:
The main objective decided in 2015 Paris Agreement was to maintain the globalaverage temperature rise below 2 K compared to the levels in the pre-industrial era. Therefore, reduction of the CO2 concentration in the atmosphere is urgent. CO2 capture and storage (CCS) technologies at high temperatures result attractive for industrial applications due to the possibility of direct operation with the exhaust gases. Materials such as alkali ceramics, alkaliearth oxides, etc. have been developed for this purpose [1]. However, the technologies that combine the capture and regeneration/conversion of CO2, require the development of dualfunction catalysts [2,3]. Therefore, this contribution presents some data corresponding to a mechanistic approach of the CO2 Storage-Regeneration process of an unsupported Ni-Ba model catalyst capable of operating in transient and cyclic regime, alternating a stage of capture of CO2 contained in exhaust gas streams and a second stage of catalyst regeneration through the injection of methane pulses with the production of hydrogen enriched streams (syngas) by preferential dry reforming in situ using labeled molecules (13CO2 and CD4).
