CHAIN COMBUSTION FOR HYDROGEN STORAGE AND SEPARATION

本研究已被用于直接生产基于燃烧合成技术的氢储存合金。The obtained accomplishments were ：1） Direct synthesis of MgHイD22イD2+MgイD22イD2 was successfully obtained by simply heating up the well-mixed metals at pressurized hydrogen atmosphere， without any activation treatment。该产品的特性是通过热分析和PCT设备测量的。2）实验室规模实验设备也已使用，用于优化操作条件。作为一个结果，产品达到了7质量%的氢存储容量;这是一个世界记录，相当于基于镁合金的氢存储容量。

This study was carried out to directly produce hydrogen storage alloy based on the technology of combustion synthesis. The obtained accomplishments were :1) Direct synthesis of MgHィイD22ィエD2+MgィイD22ィエD2NiHィイD24ィエD2 was successfully obtained by simply heating up the well-mixed metals at pressurized hydrogen atmosphere, without any activation treatment. The property of the product was measured by thermal analysis and PCT equipment.2) The lab-scale experimental apparatus was also employed, for optimizing operating conditions. As a result, hydrogen storage capacity of the product reached 7mass% ; this was a world record as hydrogen storage capacity of magnesium based alloy.
