We have calculated the equilibrium adsorption for all clathrates at 6 pressures and 7 temperatures between 200 K and 350 K. For the examples presented here, we have extended the temperature range to 400 K to better show the We note that the adsorption isotherms are generally not strictly monotonic, which is an artefact that arises because the calculations are not completely converged. Longer Monte Carlo simulations are probably needed to obtain reliable quantitative estimates for the gas adsorption, but to completely converge all 10.000 simulations would be prohibitively costly and beyond the scope of this initial screening.
