<![CDATA[Carbon dioxide (CO2) is one of the most critical greenhouse effect causes. One method that can reduce the problem of global warming is by converting CO2 and utilizing it into a CO2 hydrogenation reaction into methane. This research aims to obtain methane gas from CO2 gas using a Fixed Bed Reactor for the CO2 methanation process. This research uses Ni/Al2O3 catalyst as support and Fe metal as a promoter with in situ method by varying the amount of Fe metal promoter up to 1gr - 5gr and time variation of 30 minutes, 45 minutes and 60 minutes. The highest methane gas yield was obtained in sample 15 with more Fe metal promoter 5 gr (variation 1-5 gr) for 60 minutes (variation 30, 45, and 60 minutes), which amounted to 12.54%. The amount of Fe metal promoter and the length of time used is directly proportional to the methane gas (CH4) produced. This is because the addition of Fe as a promoter can increase catalyst activity and catalyst stability, so that the catalyst can work well in converting CO2 into methane thermal gas.Keywords: Carbon Dioxide, CO2 Methanation, Catalyst Ni/Al2O3, Promoter Fe, Methane (CH4).]]>
