Making Methane Gas from CO2 using Ni/Al2O3 Catalyst in a fixed bed reactor

Abstract

CO2 emissions are a component of greenhouse gases, it is estimated that around 18.35 billion tons of CO2 are released each year (Sulistyono, 2012). This is the result of the global economic recovery from the COVID-19 pandemic. IEA data shows that industrial processes and energy combustion account for nearly 89% of the energy sector's greenhouse gas emissions by 2021, with greenhouse gas emissions from gas combustion of just 0.7%. Converting CO2 to chemicals, or hydrogenating CO2 to methane, is one way of reducing CO2 in the atmosphere. Many studies have been conducted on how CO2 turns into CH4 using various methods, catalysts and other variables. The aim of this research is to make a fixed reactor bed for CO2 methanation. In addition, this research will use a nickel catalyst with alumina support (Al2O3).The method used is in situ. In this study, CO₂ was used as a raw material with a Ni/Al2O3 catalyst. The NaOH concentration was adjusted with variations of 1M, 1.5M, 2M, 2.5M, 3M. The CO2 flow rate was adjusted with 0.1 L/Minute, 0.2 L /Minute, 3 L/Minute Operating Time 60 minutes at 55°C. For the analysis of the Methane (CH) gas produced, it will be analyzed using a Multi Gas Detector Analyzer.
