Abstract
(EN)
Provided is a method for storing hydrogen using a structure-H clathrate hydrate. According to the method, by means of a hydrogenation reaction of an aromatic compound, hydrogen is stored in an alkane product obtained after the hydrogenation in the form of hydrogen protons, and then the alkane product forms a structure-H clathrate hydrate with water to form a cavity, so that hydrogen is encaged in the cavity of the clathrate hydrate. Compared with other hydrogen storage methods, the present method has the advantages of environmental protection, economy, and safety. Compared with conventional hydrate-based hydrogen storage methods, the present method has higher hydrogen storage density and milder conditions.

La présente invention concerne un procédé de stockage d’hydrogène au moyen d’un hydrate de clathrate de structure H. Selon le procédé, au moyen d’une réaction d’hydrogénation d’un composé aromatique, de l’hydrogène est stocké dans un produit alcane obtenu après l’hydrogénation sous la forme de protons d’hydrogène, puis le produit alcane forme un hydrate de clathrate de structure H avec de l’eau pour former une cavité, de sorte que l’hydrogène est encagé dans la cavité de l’hydrate de clathrate. Par rapport à d’autres procédés de stockage d’hydrogène, le présent procédé présente les avantages d’une protection environnementale, d’une économie et d’une sécurité. Par rapport à des procédés conventionnels de stockage d’hydrogène à base d’hydrate, le présent procédé présente une densité de stockage d’hydrogène plus élevée et des conditions plus douces.

提供一种利用H笼型水合物储氢的方法。该方法通过芳香族化合物的加氢反应,令氢气以氢质子的方式储存在加氢后的烷烃产物后,再将该烷烃产物与水形成H笼型水合物以形成空穴,从而将氢气包裹在笼型水合物的空穴中。与其他储氢方法相比,该方法具有环保,经济和安全等优点。与单纯的水合物储氢方法相比,该方法储氢密度更高,条件更温和。
