Abstract
Effects of H2SO4 and KOH treated activated carbon and tetrahydrofuran (THF) on methane hydrate formation kinetics were investigated in a fixed volume crystallizer at 6 and 8 MPa and 277.15 K. The addition of the untreated activated carbon enhanced the kinetics of the hydrate formation at 8 MPa, while adding the carbon treated by H2SO4 and KOH increased the gas consumption during the hydrate formation and its kinetics at 6 MPa. Similarly, the presence of THF also enhanced the hydrate formation kinetics at the low pressure (6 MPa). Moreover, the experiment conducted with the treated activated carbon and 5.88 mol% THF showed multiple nucleation of the hydrate formation. The highest water conversion to the hydrates was achieved at 64.9% in the system with H2SO4 treated activated carbon.
