Process for removing carbon dioxide from a gas stream

The invention relates to a process for removing carbon dioxide from a carbon dioxide containing gas (1) stream comprising the steps of: (a) contacting the carbon dioxide containing gas stream with fluidized solid adsorbent in a riser adsorption zone (2) to obtain a carbon dioxide-depleted gas stream and fluidized carbon dioxide-enriched solid adsorbent; (b) separating (4) at least part (5) of the carbon dioxide-depleted gas stream from the fluidized carbon dioxide-enriched solid adsorbent (6); (c) passing at least part of the fluidized carbon dioxide-enriched solid adsorbent (6) as obtained in step (b) to a riser regeneration zone (7) to obtain a carbon dioxide-enriched gas stream and a fluidized carbon dioxide-depleted solid adsorbent; (d) separating (10) at least part (11) of the carbon dioxide-enriched gas stream as obtained in step (c) from the fluidized carbon dioxide-depleted solid adsorbent (12) as obtained in step (c); and (e) recycling at least part (12) of the fluidized carbon dioxide-depleted solid adsorbent as obtained in step (d) to step (a).
