Research progress on modification methods for calcium looping thermochemical heat storage
摘要
Abstract
Recent advances in calcium looping thermochemical heat storage technologies are summarized,with a focus on the current research status of physicochemical properties,modification strategies,reactor design,and system integration of calcium-based materials.The main types of calcium-based materials are introduced,including naturally occurring,chemically synthesized,doped,and composite calcium-based materials,followed by a detailed discussion of how their physical characteristics and chemical properties(particle size,specific surface area,pore structure,thermal conductivity,and mechanical strength)influence heat storage performance.The physicochemical properties of these materials are thoroughly discussed,indicating their significant influence on heat storage efficiency and cyclic stability.The modification methods for calcium-based materials are introduced in detail,including physical modification such as particle size control and support addition,and chemical modification like metal oxide doping and surface coating.Through these methods,the cyclic stability and sintering resistance of calcium-based materials can be significantly enhanced.The design and optimization of calcium looping heat storage reactors and systems are discussed,including fixed-bed,fluidized-bed,and other novel reactor types.These reactors exhibit respective advantages and challenges in terms of heat and mass transfer efficiency,particle attrition balance,and system integration flexibility.The synergistic effects between reactor types and system configurations are analyzed,and the advantages of calcium looping heat storage in terms of heat storage density and mechanical strength are further explored,as well as challenges such as material deactivation,low system efficiency,and economic feasibility.Future research directions are outlined,highlighting the need to further develop highly stable materials,optimize reactor design,and conduct full life-cycle techno-economic analysis to promote the commercial application of calcium looping thermochemical heat storage technology.关键词
