“…Many of the published works on the separation of CO 2 from biogas streams are based on adsorption on zeolites [21,23,[31][32][33]. However, activated carbons show a high adsorption capacity at atmospheric pressure and present important advantages over zeolites, such as their hydrophobicity, their significant lower cost and the lower amount of energy required to regenerate them.…”

The biological production of H 2 by dark fermentation is being extensively investigated due to the great potential of the two-phase hydrogen/methane fermentation process for recovering energy from carbohydrate-rich wastes. However, the purification of the bio-hydrogen and biogas obtained is needed to produce high-purity H 2 and CH 4 streams appropriate for industrial application. In this study, the performance of three activated carbons (No1KCla-600, No1KClb-1000 and No2OS-1000), synthesized from phenol-formaldehyde resins, as potential adsorbents for CO 2 capture from bio-hydrogen and biogas streams has been evaluated under dynamic conditions. Adsorptiondesorption cycles by means of temperature swings were conducted at ambient temperature and atmospheric pressure with CO 2 /H 2 (40/60 and 70/30 vol.% at normal conditions) and CO 2 /CH 4 (50/50 vol.% at normal conditions) binary gas mixtures in a purpose-built fixed-bed set-up. The performance of the resin-derived carbons to separate CO 2 was superior to that of reference commercial carbons in terms of CO 2 uptake, breakthrough time and column efficiency. These adsorbents presented high * Corresponding author.

“…Our previous calculations show that the aperture of ZIF-7 is increased by 0.09 nm with the adsorption of CO 2 at the narrowest site, surrounding by three benzene rings [35]. This high flexibility of the narrow windows in ZIF-7 upon the adsorption of guest molecules is responsible for the step region of adsorption isotherms within a narrow pressure range and the strong adsorption/desorption hysteresis [33,36]. This phenomenon is also applicable to other gases, including N 2 O and C 2 eC 4 hydrocarbons [9,35].…”
