This study evaluates CO2 methanation over Ni/Co zeolite catalysts with CeO2 promoters, comparing thermal catalysis (TC) at 200-400°C and plasma-assisted thermal catalysis (PTC) at low temperatures. TC achieved 94-99% CO2 conversion at 400°C, while PTC enabled low-temperature CH4 production, highlighting potential for energy-efficient CCUS.

📄 Abstract（原文）
Carbon capture utilization and storage (CCUS) is a crucial strategy platform for meeting net-zero emissions goals. In this research, the methanation reaction - carbon dioxide (CO2) waste gas converted into methane (CH4) fuel gas - was evaluated at elevated temperatures (200-400 °C) using a thermal catalytic (TC) process and at low temperatures (25-150 °C) using a plasma-assisted thermal catalytic (PTC) process. The dry-impregnation method was used to prepare catalysts in the formula of Ni-xCeO2/LTA-5A and Co-xCeO2/LTA-5A, where x is a CeO2 promoter amount varied from 0-15 wt.%. It aims to seek its effect on catalytic activity and productivity. A constant 15 wt.% of Ni and Co active metals were mobilized on zeolite LTA-5A supporters. The advanced techniques i.e. SEM-EDX and BET chemisorption were performed to characterize the surface and bulk properties of all catalysts. In the TC process for all prepared catalysts, the temperature variable highly affected the CO2 conversion and CH4 selectivity - resulting in 94-99% CO2 conversion and 93-95% CH4 selectivity at 400 oC. An appropriate amount of 5 wt.% CeO2 prompter could promote and stabilize the catalytic performance. The nickel-based metal catalyst showed a positive sign of CH4 production at low-temperatures DBD plasma-assisted thermal catalytic (PTC) process.
