CONTINUOUS-MOTION DIRECT AIR CAPTURE SYSTEM

A system and a method for continuously separating carbon dioxide from gas mixtures, utilizing a continuous loop of porous monoliths which support a sorbent within its pores. Continuously exposing a portion of the continuous loop of monoliths to a flow of gas mixture containing a minor proportion of carbon dioxide, to adsorb carbon dioxide from the flow. The loop passes through a sealed regeneration and carbon dioxide capture assembly located astride a portion of the loop, and which is capable of sealingly containing a monolith in relative movement through the assembly. The assembly chamber comprises a plurality of separately sealed zones, including at least one zone for purging oxygen from the monoliths, -a subsequent zone for heating the monolith to release the adsorbed carbon dioxide, and another cooling zone for cooling the monolith prior to reentering the adsorption portion of the loop where it is exposed to oxygen.
