CHAIN COMBUSTION FOR HYDROGEN STORAGE AND SEPARATION

This study was carried to directly produce hydrogen storage alloy based on the technology ofcombustion synthesis. The obtained accomplishments were:1) Direct synthesis ofMgH - D22 - D2+Mg - D22 - D2NiH - D24 - D2 was successfully obtained by simply heating up the well-mixedmetals at pressurized hydrogen atmospherewithout any activation treatment. The property of The product was measured by thermal analysis andPCT equipment.2) The lab-scale experimental apparatus also employedfor 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
