Methane hydrate is successfully prepared through the reaction of Al4C3 and H2O using a laboratory designed high pressure hydrate apparatus.Experimental results indicate that this method is an effective solution to introduce CH4 in the synthetic experiments of methane hydrates,and the pressure-temperature formation conditions of the methane hydrate approach the natural situation.In addition,the products of the reaction of Al4C3 and H2O can simulate the real formation process of methane hydrate in the ocean environment and offer an effective route to natural gas hydrate research.With this method,a preliminary study is presented concerning the formation,dissociation and dynamic processes of methane hydrate under different temperature and pressure conditions.
