Abstract: Systems and methods are provided for performing direct air capture using a rotary sorbent bed configuration. The rotary sorbent bed is supported on a wheel that serves as a framework structure for supporting the sorbent bed. The sorbent bed can include one or more monoliths that form the support material for the sorbent bed, and a sorbent supported on the one or more monoliths. The rotational path of the sorbent bed passes through the enclosure that allows for sealing of the portion of the sorbent bed within the enclosure. Optionally, the enclosure can contain a plurality of sub-zones that facilitate temperature control and/or pressure control within the enclosure while allowing for recovery of a high purity CO2 stream from the desorption zone. The rotary sorbent bed configuration can allow for continuous or semi-continuous capture of CO2 while reducing or minimizing contact of the sorbent bed with oxygen at elevated temperature.
