The following table is obtained from this reference (https://doi.org/10.1016/j.seppur.2022.121604), which summarised a few reports regarding the performance of ICCU-RWGS, in relation to the conversion of
“The stability of Ni/CeO2-CaO bifunctional combined material was presented by carrying out 20 cycles of ICCU-RWGS at 650 °C (Fig. 9). The Ni/CeO2-CaO possessed a < 5% decrease
“The performances of ICCU-RWGS were also significantly affected by the reaction temperature. For example, 87.4% and 25.6% of CO2 conversions were obtained over Ni/CeO2-CaO at 550 °C
During ICCU-RWGS, two key steps are involved, including the capture of CO2, and the regeneration of sorbent (simultaneous CO2 utilisation). The following work (https://doi.org/10.1016/j.seppur.2022.121604) reported
The following work reported the use of different supports for Ni-based catalysts, which were physically mixed with CaO for ICCU-RWGS. “The ICCU-RWGS performance using Ni/support-CaO
Membrane based materials have also been developed for ICCU-DRM. The details methods are indicated below, copied from this reference (https://doi.org/10.1016/j.cej.2019.122182): “Preparation of the powder materials
The simple method for the preparation of dual functional materials (or combined functional materials) is to mix adsorbent (e.g. CaO) and catalysts (e.g. Ni/Al2O3) together.
Except physical mixing of sorbent and catalyst, and impregnating sorbent with catalyst, one-pot synthesis of dual functional materials (DFMs) is another common method. In the
