In recent years, methane hydrate has attracted much attention not only as a new energy resource but also as a means for methane storage and transportation. However, the slow formation rate of methane hydrate is considered to be a critical issue for the storage and transportation. This work investigated the synergistic effects of activated carbon and tetrahydrofuran (THF) on methane hydrate formation. Activated carbon is added to pre-adsorb water and THF solution with the ratio of water or THF solution to the dry carbon equal to 1. Then, the hydrate formation experiments were performed at 6 and 8 MPa and 277.15 K. The addition of the activated carbon enhanced the kinetics of the hydrate formation at 8 MPa. The presence of THF also enhanced the hydrate formation kinetics at the low pressure (6 MPa). Moreover, the experiment conducted with the activated carbon and THF showed multiple nucleation of the hydrate formation, indicating the synergistic effects of the two materials.
