Emerging Technologies and Biological Systems for Biogas Upgrading

Emerging Technologies and Biological Systems for Biogas Upgrading systematically summarizes the fundamental principles and state-of-the-art of biogas cleaning and upgrading technologies, with a special emphasis on biological process for CO2, H2, H2S, siloxane, and hydrocarbon removal. After analyzing the global scenario of biogas production, upgrading and utilization, this book discusses the integration of methanation processes to power-to-gas systems for methane production and physiochemical upgrading technologies, such as chemical absorption, water scrubbing, pressure swing adsorption and the use of membranes. It then explores photosynthetic processes using algae, hydrogen-mediated microbial techniques, electrochemical, bioelectrochemical and cryogenic approaches, and the use of crystalline microporous metal-organic frameworks (MOFs). In addition, hydrogen sulfide removal with biofilters for hydrogen sulfide is covered, as well as the removal of siloxanes through polymerization, peroxidation, biological degradation and gas-liquid absorption. Finally, issues of mass transfer limitation in biomethanation from waste gas, biogas upgrading and syngas, life cycle assessment of upgrading technologies, techno-economic aspects, challenges for upscaling, and future trends are presented and considered.
