<p>This invention relates to a selective adsorption of carbon dioxide from mixtures thereof with non-acidic gases such as e.g. nitrogen and methane. The adsorption and regeneration cylces are suitably performed at pressures from 1 mbar absolute to 40 bar absolute and at temperatures from -80 DEG C to 150 DEG C. Separation of carbon dioxide and methane is particularly important in the petroleum industry for use of recovered CO2 in enhanced oil recovery process.</p> |
