Abstract

Carbon dioxide (CO2) is one of the biggest contributors to the greenhouse effect. Based on International Energy Agency (IEA) data, global emissions of carbon dioxide (CO2) from burning energy and industrial activities will reach 36.8 billion tons in 2022. The increase in emissions in 2022 will mainly come from burning coal and fuel oil (Fuel Oil). Carbon dioxide emissions from coal rose 1.6% while fuel oil emissions increased 2.5%. One effort to reduce carbon dioxide emissions is to convert carbon dioxide into methane gas (CH4) which can be used as fuel. This research aims to produce methane gas from carbon dioxide using Ni/Al2O3 catalyst treatment and varying CO2 flow rates. In this research, CO2 was used as a raw material with a Ni/Al2O3 catalyst and Zn metal. Based on the research results, the highest conversion yield of methane gas was 49.23% with a variation of 0.05 L/minute with Ni_R4 catalyst treatment

Abstract

Carbon dioxide (CO2) is one of the biggest contributors to the greenhouse effect. Based on data from the International Energy Agency (IEA), greenhouse gas (GHG) emissions continue to increase, reaching 37.8 billion tons in 2024. One way to reduce carbon dioxide (CO2) is to convert carbon dioxide (CO2) into methane (CH4) through a methanation process using a Fixed Bed Reactor. This study was conducted by varying the mass of Ni/Al2O3 catalyst between 55 grams and 60 grams and the operating time between 90, 100, 110, 120, and 130 minutes, as well as adding 20 grams of Zn promoter to improve catalyst stability performance. A Multi Gas Detector Analyzer was used to analyze the methane (CH4) gas produced. The results of this study showed that the highest percentage of methane gas (CH4) produced was obtained in sample 10 with a Ni/Al2O3 catalyst mass of 60 grams and an operating time of 130 minutes, which was 58.35%.
