Due to the low-carbon transformation requirement of domestic coal power units in the “carbon peak and carbon neutrality” situation

exploring a new industrialization way in solid adsorption CO_2 capture technology on CCUS

and developing a new solid chemical sorbent to capture CO_2 from coal-fired flue gas

are important for realizing large-scale application of such technology. Current researches on solid adsorption CO_2 capture technology in China mainly focus on the theory level. This study systematically reviews and analyzes the research progress on solid sorbent materials at low

medium and high temperatures

points out the directions for further research

and identifies the research content needed for scaled application. A typical high-temperature calcium-based sorbent is used as an example to analyze the industrial applications of the entire process

including the sorbent preparation

sorbent scaling up

sorbent granulation and molding

reactor design

and CO_2 capture system verification for calcium looping. This study can provide references for aspects including further key technology research and breakthroughs

the construction of a full process for solid adsorption CO_2 capture with high activity and low energy requirement

and the realization of the large-scale application of solid adsorption CO_2 capture technology.
