A method and a system for removing carbon dioxide directly from ambient air, using a sorbent under ambient conditions, to obtain relatively pure CO 2 . The CO 2 is removed from the sorbent using process heat, preferably in the form of steam, at a temperature in the range of not greater than about 130° C., to capture the relatively pure CO 2 . Increased efficiency can be achieved by admixing with the ambient air, prior to contacting the sorbent, a minor amount of a preferably pretreated effluent gas containing a higher concentration of carbon dioxide. The captured carbon dioxide can be stored for further use, or sequestered permanently.

The present invention generally relates to high rate adsorbents and a method for their manufacture involving the steps of component mixing, extrusion, spheronization and calcination. The component mixing can involve both dry mixing in addition to wet mixing of an adsorbent with a binder, if required, and a fluid such as water. The paste so formed from the mixing stage is extruded to produce pellets which are optionally converted to beads by spheronization using in one embodiment, a marumerizer. The product is harvested and calcined to set any binder or binders used and/or burn out any additives or processing aids. This basic manufacturing scheme can be augmented by extra processing steps including ion exchange and activation to alter the composition of the adsorbents, as required.
