Chemical looping deoxygenated gasification: An implication for efficient biomass utilization with high-quality syngas modulation and CO2 reduction

Chemical looping gasification is a promising technology for biomass utilization. However, the biomass-derived products contain tar and CO2, which seriously affects the syngas quality and hinders its development. A new approach, chemical looping deoxygenated gasification (CLDG), was proposed for high-quality, H2/CO-tunable syngas generation with CO2 utilization via redox looping of CaO + Fe ↔ Ca2Fe2O5. The CLDG process involves a deoxygenation...
