Abstract

The transportation sector is one of the largest contributors to greenhouse gas emissions, which play a significant role in global climate change. One preventative measure that can be taken is to convert carbon dioxide (CO₂) into methane (CH₄), known as the CO₂ methanation process. The purpose of this study was to produce methane gas with a higher conversion percentage, as well as to observe the effect of variations in operating temperature and KOH liquid concentration on the methane gas produced. In this study, CO₂ was used as the raw material with a Ni/Al₂O₃ catalyst and zn promoter. The temperature was set at 165°C, 175°C, 185°C, 195°C, and 205°C, with KOH liquid concentrations varying from 4M to 5M. The resulting methane (CH₄) gas will be analyzed using a Multi Gas Detector Analyzer.
