Fluidized Bed Reactors for Carbon Capture A Review of Advancing Combustion and Sorption Techniques for Decarbonization

This open access book provides a perspective on CO2 capture technologies that employ fluidized bed rectors, (FBRs) involving pre-combustion gasification, oxy-fuel combustion, chemical looping combustion, calcium looping process, and low-temperature sorption. The state-of-the-art progress from the lab-scale FBRs to pilot-scale demonstration facilities is summarized, and the remaining challenges are discussed. Moreover, this book also discussed the future solutions to overcome existing barriers in the application of FBRs for CO2 capture and provided an outlook on potential advancements and improvements. The authors anticipate endeavors made herein can impel the commercialization of fluidized bed technologies for CO2 capture from large industrial sources.

Lunbo Duan obtained his doctoral degree in Environmental Engineering from Southeast University in 2010. Funded by Engineering and Physical Sciences Research Council (EPRSC), he worked as a research fellow at Cranfield University in UK from 2014 to 2015. He has received a grant from the Excellent Young Scientist Fund of National Natural Science Foundation of China in 2019. Now he is a professor at the School of Energy and Environment at Southeast University. Professor Duan has built the first oxy-fuel fluidized bed combustion system with warm flue gas circulation in the world. He has established an innovative method of oxy-fuel circulating fluidized bed combustion with high efficiency and low emission based on oxygen/warm flue gas circulation. He has published more than 100 SCI papers with an H-index of 47.
