Outline of Final Research Achievements

The catalyst of a ferrous-oxide-graphite system which takes effect was used for the generation speed of CO2 gas-hydrate. The carbon fiber which the large surface area accompanied by fine structure has was made to support the catalyst, and the contact probability of 3 phase-boundaries (gas, fluid, and catalyst) was controlled. Introducing the carbon fiber catalyst estimated the performance of the heat cycle by gas-hydrate. As a result, the generation speed of gas-hydrate increased two to three times over the past. It is expected that development of the new gas-hydrate storage-of-electricity system driven by a small temperature gradient progresses from now on.
