摘要
介绍了熔融碱金属碳酸盐的物理化学特性及其在能源转化过程中的应用,包括作为催化剂、反应介质、电解质及热载体等。混合熔盐比纯组分具有更低的熔点及较高的催化活性,通过对不同碱金属碳酸盐的合理匹配可以优化其物化性能(如熔点、黏度等),从而可提高其催化活性、增强流动性及降低电极材料NiO在熔融碳酸盐中的溶解度。
The properties and applications in energy conversion technology as catalyst, reaction medium, electrolyte and heat carrier of molten alkali carbonate ate briefly reviewed. The eutectic of molten alkali carbonate mixture has lower melting point and higher catalytic activity as compared with single molten salt. The physical properties （e. g. melting point and viscosity ） can be optimized by means of adjusting optimal combination of different alkali carbonates, hence the catalytic activity and fluidity of the molten salt can be improved and the solubility of electrode material NiO in molten alkali carbonate can be decreased.
