Influence of reaction temperature using Ca1Ni0.1Ce0.033 for ICCU-RWGS

https://doi.org/10.1016/j.apcatb.2018.11.040

“The influence of reaction temperature was studied using the Ca₁Ni_0.1Ce_0.033 catalyst. When increasing the carbon capture and conversion temperature from 650 to 700 and further to 750 °C, as shown in figures below, it is found that the decomposition rate of CaCO₃ is dramatically increased after switching to H₂. However, the rate of the RWGS reaction is marginally increased due to the controlling step of CO₂ conversion with limited active Ni species. Therefore, 650 °C is optimal for carbon capture and CO production in this work.”
