基于CaO/CaCO3循环的太阳能高温储热具有储能密度大、能效高等优点,钙基材料的循环储能稳定性和传热、传质性能受限是该技术亟需解决的瓶颈问题之一。本项目采用模板法并添加高热导率抗烧结支撑体,制备微纳中空结构复合钙基材料并实现精准调控。分别确定微纳中空结构复合钙基材料的合成参数及循环储能反应特性,探讨高浓度水蒸气储热条件下复合钙基材料的长期循环储能容量;建立复合钙基材料储能性能与微纳中空结构之间的内在联系,采用密度泛函理论阐明固态离子掺杂在CaO表面的迁移机制及储热结构动态演化规律,确立储热反应条件对复合钙基材料热动力学过程的影响机理;研究复合钙基材料热物性参数随改性参数的变化关系,建立适用于复合钙基材料导热系数的新方程,确定复合钙基材料内部温度分布规律及热扩散机制。项目实施为发展新型高效钙基储能材料提供新思路,为钙基储能材料的改性设计提供机理诠释,为热化学储能技术工程优化提供理论依据。
英文摘要
The high-temperature solar energy storage based on the CaO/CaCO3 cycle has advantages of high energy storage density and high energy efficiency. The instability of cyclic energy storage and the limited heat and mass transfer performance of calcium-based materials are main problems currently. The calcium-based materials with micro-nano hollow structure are prepared and accurately controlled using high thermal conductivity and anti-sintering support materials by template method in this work. The synthetic parameters and cyclic energy storage performance of the synthetic calcium-based materials with micro-nano hollow structure will be determined, respectively. The long-term cyclic energy storage capacities of the synthetic calcium-based materials under the condition of high-concentration steam will be investigated. The internal relationship between the energy storage performance of the synthetic calcium-based materials and the micro-nano hollow structure will be established. The migration mechanism of solid ion doped on the CaO surface and the dynamic evolution law of structure model during the heat storage process will be revealed by density functional theory. The mechanism of the effect of reaction conditions on the thermodynamic process of the synthetic calcium-based materials will be determined. The relationship between thermophysical properties of the synthetic calcium-based materials and their synthetic parameters will be studied. New equations for the thermal conductivities of the synthetic calcium-based materials will be established. The internal temperature distribution and the thermal diffusion mechanism of the synthetic calcium-based materials will be determined. The implementation of the project will provide new ideas for the development of efficient calcium-based energy storage materials, provide mechanism interpretation for the modification of calcium-based energy storage materials and provide theoretical basis for the engineering optimization of the thermochemical energy storage technology.
