Patent attributes
Systems and methods for capturing carbon dioxide (CO2) in exhaust gases of a vehicle include delivering the exhaust gas to a cooled section of a rotary contactor, the rotary contactor including openings that extend from a first side of the rotary contactor to a second side of the rotary contactor. The CO2 of the exhaust gas is adsorbed with a sorbent of the cooled section of the rotary contactor, where the non-CO2 components of the exhaust gas pass through the openings. The cooled section of the rotary contactor is heated with a hot fluid of the vehicle to release the adsorbed CO2 and convert the cooled section of the rotary contactor to a heated section of the rotary contactor. The heated section of the rotary contactor is cooled to convert the heated section of the rotary contactor back to the cooled section of the rotary contactor.
