Application of Fluidized Bed Reactors for Carbon Capture

With the aim to mitigate the global warming, carbon capture, utilization and storage (CCUS) technology is expected to play a pivotal role in the decarbonization of industrial production and the achievement of a carbon-neutral future, thus attracting broad research interests. In particular, the promise of fluidized bed reactors for CO₂ capture from large industrial sources has been demonstrated by a suite of CCUS technologies. This review provides a perspective on CO₂ capture technologies that employ fluidized bed rectors, involving oxy-fuel combustion, chemical looping combustion, calcium looping, and low-temperature sorption. Based on an overview from the lab-based fluidized bed reactors to pilot-scale demonstration facilities, the state-of-the-art progress summarized and remaining challenges are discussed. Further research orientation of fluidized bed reactors for CO₂ capture is also outlooked in the end. We anticipate endeavors made in this review can impel the commercialization of fluidized bed-based reactors for CO₂ capture from large industrial source.
