METHOD FOR STORING HYDROGEN USING STRUCTURE-H HYDRATE

摘要

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.
