Dual functional materials (DFMs) for ICCU-RWGS can be physically mixed adsorbent and catalyst, or one-unit catalytic sorbent, or adsorbent impregnated with catalyst. In this article,
The following content, obtained from https://doi.org/10.1016/j.jcou.2016.04.003, shows the procedure of ICCU-RWGS. The gas analysis was carried out using IR spectrometer. “The experimental system mainly consists
The following information is obtained from (https://doi.org/10.1016/j.jcou.2022.102049) regarding the calculation of CO selectivity and CO2 conversion. “In analysis, the moisture in the outlet gas was
In ICCU-RWGS, the composition of gases is determined normally by an online gas analyser. Key performance indicators include CO2 conversion, the capacity of CO2 capture,
Fixed bed reactors are normally used for ICCU-RWGS. CO2, N2 and H2 are used to provide the CO2 source, purge gas and reduction agent. Gas
Dr Wu’s group initially reported that pure CaO could act as sorbent and catalyst for ICCU-RWGS without transition metals; and high efficiency and conversion were

https://doi.org/10.1016/j.ccst.2021.100001 ” The formation of calcium carbonate (CaCO3) can be clearly observed from the in-situ DRIFTS after 30 mins CO2 adsorption and 8 mins purge.
https://doi.org/10.1016/j.ccst.2021.100001 “Based on the above results, we propose an improved ICCU process including CO2 capture, conversion and re-capture to deliver pure syngas from flue gas (as illustrated in Fig. 3).
The following content is related to the use of two beds to realise continuous ICCU-RWGS, by switching gases, and copied from https://doi.org/10.1021/acscatal.1c05339. “A long-term continuous
