相变石蜡是一种重要的相变贮能材料,其应用十分广泛。相变石蜡中的有色物质对石蜡发生相变的温度范围以及贮（放）热量都有很大的影响。本试验采用活性白土、硅胶以及活性炭为吸附剂分别对相变石蜡进行脱色,研究了吸附温度、吸附时间和吸附剂用量对脱色率的影响,并对这3种吸附剂的吸附性能进行比较。

Phase change paraffin is widely used as an important material for thermal energy storage. The color substances in the paraffin are detrimental to its thermal performance. The decolorizing of the paraffin was carried out using activated clay, silicon gel, and activated carbon as absorbents. The effects of adsorbing temperature, absorbing time, and amount of absorbents on decolorizing rate of the paraffin were investigated. The adsorption characteristics of activat...
