Abstract:
(EN) A process for producing a hydrogen-generating material comprising at least one metal powder selected from the group consisting of an aluminum powder and an aluminum alloy powder, characterized by mechanically pulverizing aluminum or an aluminum alloy in a treating solvent comprising an organic solvent having the property of corroding aluminum to thereby form a metal powder composed of flaky particles. The hydrogen-generating material comprises, for example, at least one metal powder selected from the group consisting of an aluminum powder and an aluminum alloy powder, the metal powder being composed of flaky particles and at least 60 wt.% of the aluminum contained in the metal powder being present in a metallic state. The metal powder has a carbon content, as determined by the infrared absorption method after combustion, of 0.5 wt.% or lower.
(FR) La présente invention concerne un procédé de production d'une matière générant de l'hydrogène comprenant au moins une poudre métallique choisie dans le groupe comprenant une poudre d'aluminium et une poudre d'alliage d'aluminium. Le procédé est caractérisé par la pulvérisation mécanique d'aluminium ou d'un alliage d'aluminium dans un solvant de traitement comprenant un solvant organique capable de corroder l'aluminium afin de former une poudre métallique composée de particules lamellaires. La matière générant de l'hydrogène comprend par exemple au moins une poudre métallique choisie dans le groupe comprenant une poudre d'aluminium et une poudre d'alliage d'aluminium, la poudre métallique étant composée de particules lamellaires et au moins 60 % en poids de l'aluminium contenu dans la poudre métallique étant présent dans un état métallique. La teneur en carbone de la poudre métallique, déterminée par le procédé par absorption des infrarouges après combustion, est inférieure ou égale à 0,5 % en poids.
(JA)  本発明は、アルミニウム粉末およびアルミニウム合金粉末よりなる群から選択される少なくとも1種の金属粉末を含有する水素発生材料を製造するにあたり、アルミニウムに対する腐食性を有する有機溶媒を含む処理用溶媒中で、アルミニウムまたはアルミニウム合金を機械的に粉砕して、鱗片状の形状を有する金属粉末とすることを特徴とする。また、本発明が提供する水素発生材料は、例えば、アルミニウム粉末およびアルミニウム合金粉末よりなる群から選択される少なくとも1種の金属粉末を含有し、前記金属粉末は鱗片状の形状を有し、前記金属粉末に含有されるアルミニウムの60重量%以上が金属状態で存在しており、かつ、燃焼赤外吸収法により測定される前記金属粉末の炭素含有量が0.5重量%以下である。
