| Summary: | Depletion issues and the negative environmental impact of fossil fuels have driven the need to develop renewable energy resources that are greener and environmentally friendly. Various efforts have also been made around the world to improve the efficiency of current energy conversion processes and develop efficient environmentally friendly energy conversion devices. Among the available renewable resources, biomass has received much attention as it is widely available and is the fourth largest energy resource after coal, natural gas, and petroleum. Biomass has huge potential to be versatile through various conversion processes such as combustion, pyrolysis, fermentation, gasification, and anaerobic digestion. Anaerobic digestion is based on the degradation of organic waste by bacterial action in the absence of oxygen and uses far less energy than gasification, pyrolysis, or combustion. Several types of biomass can be turned into a gas combination of methane (CH4) and carbon dioxide (CO2), often known as biogas, using this technique. This chapter focuses on biogas and its upgrading technologies, especially the dry reforming method (DRM), to convert it into highly valuable intermediates (e.g., syngas). The main challenges of DRM are highlighted in this work. The catalysts that are suitable for DRM are also presented. Lastly, plasma technology, particularly microwave plasma, is also proposed to overcome the highly-stable CO2 and CH4 during DRM. ? 2024 Elsevier Ltd. All rights reserved. |
