Feasibility of hybrid thermal energy system which combines magnesium oxide/water chemical heat storage system and high-temperature process was discussed experimentally as an energy saving system. New heat storage composite material mixed with expanded graphite and magnesium hydroxide was demonstrated as high-performance material compared with conventional pure magnesium hydroxide. Pelletized material using the composite was developed also. The pellet was charged into a packed bed reactor of chemical heat storage system and measured its thermal performance. The chemical heat storage system using the composite was expected to contribute on load leveling and energy saving of a high-temperature process.

实验研究了氧化镁/水化学蓄热与高温过程相结合的复合热能系统作为一种节能系统的可行性。与传统的纯氢氧化镁相比，膨胀石墨和氢氧化镁混合的新型储热复合材料是一种高性能的储热材料。还开发了使用该复合材料的造粒材料。将该颗粒装入化学蓄热系统的填充床反应器中，对其热性能进行了测试。使用该复合材料的化学蓄热系统有望为高温过程的负荷均衡和节能做出贡献。
