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

“The influence of reaction temperature was studied using the Ca1Ni0.1Ce0.033 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.”
