다국어 초록 (Multilingual Abstract)

Carbon materials such as activated carbon (AC) can be used as a catalyst support because of its large specific area, high porosity, and adjustable pore size and its distribution. In this study, the performance of AC-based nickel catalysts were evaluated on both CO₂ methanation and methanol steam reforming (MSR) process. Those processes play important roles in supporting the shift to renewable energy. ACs were prepared by various conditions of activation process. The study showed that activated carbon supported nickel catalyst used for CO₂ methanation reaction can yield products up to 70% conversion of CO₂ and 65% of CH₄ carbon yield. AC-supported nickel catalyst used for MSR, meanwhile, could facilitate the process to achieve high value on both hydrogen yield (up to 79%) and selectivity of CO₂ (up to 90%). Methane as a side product also has a low selectivity on this process. Various analytical methods such as XRD, BET, and TEM, have also been done in order to support this study.
