Abstract: The effect of methanol on the kinetics of CH₄/CO₂ exchange in gas hydrate below the ice melting point was studied. It was shown that in the presence of 2.5 wt% of methanol at P = 2.25 MPa and T = 263 K the molar fraction of CH₄ replaced with CO₂ increased more than three times.

Keywords: gas hydrate, carbon dioxide, methane, swapping, catalyst, methanol.
