title: Experimental study of methane replacement in gas hydrate by carbon dioxide.
abstract: The process of replacement of methane molecules in clathrate hydrate by carbon dioxide is studied experimentally. The dependence of the replacement extent on the concentration of the gas mixture coexisting with the hydrate is determined. The kinetics of the replacement is governed by two relaxation modes with a characteristic time ratio of about 10.
