Translational diffusion coefficient D and mean residence time τ. Temperature dependencies of D (a) and τ (b) for methane hydrate in the sI–sII clathrate at 0.8 GPa, as obtained in the 3D and 2D diffusion models employed in this work. Error bars correspond to one standard deviation. Arrhenius fits of D are shown as dashed lines. Estimated value for D in pure methane from literature40, 41 is also reported. Legend of a also applies to b
