Abstract

The formation of methane hydrate ($CH_4$ hydrate) in silica sand and decomposition experiments were performed at $7.0^{\circ}C$ using a newly designed reactor. Temperature profile within silica sand bed was measured by thermocouples installed at different height of reactor. Both temperature and pressure are the main parameters for the formation (measured by adsorption experiment) and decomposition (measured by desorption experiment) of methane hydrate. Experiment of methane hydrate formation at 8 MPa and $7.0^{\circ}C$ showed that 70% of methane was converted to hydrate and the recovery of methane by the decomposition of methane hydrate was 82%.
