Disclosed is a method for removing carbon dioxide from a gas stream, comprising placing the gas stream in contact with a resin, wetting the resin with water, collecting water vapor and carbon dioxide from the resin, and separating the carbon dioxide from the water vapor. The resin may be placed in a chamber or a plurality of chambers connected in series wherein the first chamber contains resin that was first contacted by the gas, and each successive chamber contains resin which has been wetted and carbon dioxide collected from for a greater period of time than the previous chamber, and so on, until the last chamber. Secondary sorbents may be employed to further separate the carbon dioxide from the water vapor.

Capture of carbon dioxide (CO2) from air

The present disclosure provides a method for removing carbon dioxide from a gas stream without consuming excess energy, wherein a solid sorbent material is used to capture the carbon dioxide. The solid sorbent material may utilize a water-swing for regeneration. Various geometric configurations are disclosed for advantageous recovery of COand regeneration of the sorbent material.
