Methane gas hydrate, MGH, has cage-like crystal structures of water molecules having a methane gas in it. Under atmospheric temperature and pressure, the amount of methane gas contained in MGH is equivalent to 172 times volume of methane gas hydrate. Many researchers are planning to develop the storage and transportation system of methane gas using MGH according to gas hydrate properties. The goal of this study is to develop the technology of collection and transportation of the methane gas from small-scale methane sources. In this study, the possibility of catalyst of iron oxide and carbon was investigated. And effect of catalyst of iron oxide, carbon and its mixture on the methane hydrate formation under weak stirring condition was studied and kinetic analysis was carried out. The acceleration effect of catalyst of iron oxide, carbon and its mixture on the hydrate formation was elucidated, when they became fine and activated by the mechanical milling.
