(563c) Electrified Biogas Upgrading into Value-Added Chemicals

High-temperature methane upgrading through electrification methods has emerged as a promising alternative to the traditional syngas process for converting methane into valuable products such as olefins, aromatics, and hydrogen. This study delves into the feasibility of various electrification techniques by comparing conventional, microwave-assisted, and continuous and pulse Joule-heated coupling of methane. The research emphasizes the significance of managing gas-phase reactions and carbon formation to ensure stable operation. Furthermore, the impact of introducing CO₂ and H₂O into the methane upgrading process is assessed, offering insights into the possibility of directly upgrading wet biogas. The outcomes of this study contribute to the advancement of cost-effective and environmentally friendly approaches for enhancing the value of biogas and natural gas, potentially reducing energy consumption and capital investments associated with producing fuels and chemicals from methane.
