Abstract
The present invention is a process for adsorbing carbon dioxide from a carbon dioxide containing gas mixture comprising contacting the gas mixture with an activated carbon adsorbent having a density in the range of approximately 0.56 to 0.61 g/cc (35 to 38 lbs./ft.sup.3) and adsorbing the carbon dioxide on the activated carbon adsorbent.
Claims6
A process for adsorbing carbon dioxide and methane from a carbon dioxide and methane containing gas mixture, which also contains a product gas selected from the group consisting of hydrogen, helium and mixtures thereof, comprising contacting said gas mixture with an activated carbon adsorbent having a density in the range of approximately 35 to 38 lbs./ft.sup.3 and adsorbing said carbon dioxide and methane on said activated carbon adsorbent, while said product gas is recovered as an unadsorbed product.
