    Abstract: A capacitive deionization system includes first and second electrodes comprising tire derived carbon particles obtained from a carbonaceous waste-tire source material containing carbon black. A conductive polymer coating on the carbon particles forms coated carbon particles. The first electrode and the second electrode define a flow channel there between, having a first opening for conducting saline solution into the flow channel and a second opening for conducting treated saline solution from the flow channel. A first current collector is provided for the first electrode and a second current collector is provided for the second electrode. An electrical connection between the first and second electrodes. A method of making a system for the capacitive deionization of a salt from a liquid, and a method for the capacitive desalination of a saline solution are also disclosed.

    Abstract: A packing device for mass and heat transfer with a subject fluid includes a housing having opposing ends, and subject fluid openings at each opposing end defining a subject fluid flow path for at least one subject fluid flowing through the packing device. A plurality of mass and heat transfer plates each include an interior heat exchange fluid channel disposed between interior heat transfer surfaces of the mass and heat transfer plates. A heat exchange fluid inlet and fluid outlet can supply and remove heat exchange fluid to the heat exchange fluid channels of the mass and heat transfer plates. The mass and heat transfer plates can be oriented to define there between fluid flow channels for the subject fluid. A method and system for mass and heat transfer with a subject fluid, and a method and system for the removal of CO2 from a gas stream are disclosed.

    Abstract: A method of capturing carbon dioxide (CO2) present in air is provided. The method includes adding a carbon-dioxide-capturing device to a heating, ventilation, and air conditioning (HVAC) system of a building. The carbon-dioxide-capturing device is added to one or both of an air handler and air-distribution ductwork of the HVAC system. The method further includes circulating air including carbon dioxide through the carbon-dioxide-capturing device in the HVAC system. A direct decarbonization system for capturing carbon dioxide present in air is also provided. The system includes an HVAC unit, air-distribution ductwork connected to the HVAC unit, and a carbon-dioxide-capturing device disposed in one or both of the HVAC unit and the air-distribution ductwork. Carbon dioxide gas present in air passing through the HVAC unit or the air-distribution ductwork is removable from the air by the carbon-dioxide-capturing device.

    Abstract: A method for regenerating a bis(iminoguanidine) (BIG) carbon dioxide sorbent, the method comprising: (i) providing a carbonate or bicarbonate salt of the BIG carbon dioxide sorbent, and (ii) directly contacting the carbonate or bicarbonate salt of the BIG carbon dioxide sorbent with steam heated to a temperature within a range of 80° C.-130° C. to result in regeneration of the BIG carbon dioxide sorbent with simultaneous conversion of the carbonate or bicarbonate anions into carbon dioxide, wherein the regenerated BIG carbon dioxide sorbent is substantially removed of carbonate or bicarbonate and may optionally contain one or more adduct water molecules. In some processes, the regenerated BIG carbon dioxide sorbent is dissolved in water condensing from the steam during the contacting step to form an aqueous solution of the regenerated BIG carbon dioxide sorbent.

    Abstract: A method for regenerating an amine-containing sorbent material useful in CO2 capture, the method comprising exposing an amine-containing sorbent-CO2 complex to microwave radiation to result in release of CO2 and regenerated amine-containing sorbent that is uncomplexed with CO2, wherein the amine-containing sorbent-CO2 complex contains either: (i) a carbamate bond; or (ii) an ion pair bond of the formula




    wherein Ra, Rb, and Rc are selected from H and hydrocarbon groups containing at least one carbon atom, wherein at least one of Ra, Rb, and Rc is H; Xm− is a carbonate or bicarbonate anion, with m being 1 for bicarbonate and 2 for carbonate; and n is an integer of 1 or 2, provided that n×m=2. The method may also include re-using the regenerated amine-containing sorbent to capture carbon dioxide.
