中文摘要	hydrogen is viewed as the most potential and clearest gas energy, which is the direction for the energy future developing and has a very huge application prospect. the application of hydrogen is a new field which is involved in production, storage, translation, fuel-cell application and so on. especially, the storage of hydrogen is the restrictive factor in hydrogen economy. the traditional storage methods of hydrogen by compressing and liquefaction can not satisfy the requirement of application. therefore, attention is currently focused on the new hydrogen storage technology. and the hydrate as the solid storage material namely clathrate hydrogen hydrates opens a new direction for hydrogen storage. in this thesis, a new equipment for the hydrogen hydrate formation in high pressure was built, and the formation of hydrate in h2/the second guest (thf/ cyclopentane, both in 5.56mol% )/water system without stirring in a constant volume was studied under the condition of different pressures (10,12,14,16,18mpa) and temperature (0,2,4℃) respectively. and two different formation methods of the hydrogen hydrate were compared: (1) in h2-the second guest-water sulotion system; (2) in h2-the second guest hydrates powder system. the formation processes in the two systems were investigated and the amounts of hydrogen stored in the clathrate hydrates were calculated. the formation mechanism of hydrogen clathrate hydrate in two systems was analyzed. the results show that: (1) under the experimental conditions, the hydrogen hydrate could both be formed in two methods. (2) capacities of hydrogen in all experiments didn’t exceed 1wt%, which were improved by the pressure/temperature growing. (3) the formation rate in h2-the second guest hydrates powder system was faster than in h2-the second guest-water sulotion system obviously. (4) in h2-the second guest hydrate powder system, the hydrogen hydrate phase diffusion model was built. according to the experimental data, the adsorption coefficient and effective diffusion coefficient could be simulated, and the acticatin energies were caculated, the maximum could reach 77.5kj/mol .
