A structured adsorbent sheet, is provided including a nano-adsorbent powder, and a binder material, wherein the nano-adsorbent powder is combined with the binder material to form an adsorbent material, and a porous electrical heating substrate, wherein the adsorbent material is applied to the porous electrical heating substrate thereby forming a structured adsorbent sheet. A structured adsorbent module is provided, including a plurality of stacked structured adsorbent sheets, configured to produce a plurality of fluid passages, wherein the plurality of fluid passages have a cross-sectional shape in the direction of a fluid stream. The structured adsorbent module may have a cross-sectional shape that is trapezoidal, rectangle, square, triangular or sinusoidal. A structured adsorbent bed is provided, including a plurality of modules, stacking the modules, thereby providing a plurality of process fluid passages, and a process fluid inlet and a process fluid outlet, in fluid communication with the plurality of process fluid.

1. A method of purifying a fluid stream with a structured adsorbent unit comprising, at least one structured adsorbent unit with a cycle time C, each structured adsorbent unit comprising N adsorbing beds, wherein N is greater than or equal to 3, each adsorbing bed comprising at least 2 adsorbent mod
1. A method of purifying a fluid stream with a structured adsorbent unit comprising, at least one structured adsorbent unit with a cycle time C, each structured adsorbent unit comprising N adsorbing beds, wherein N is greater than or equal to 3, each adsorbing bed comprising at least 2 adsorbent modules, each adsorbent module comprising a plurality of stacked sheets, each sheet comprising a nano-adsorbent powder affixed together with binder material onto a porous electrical heating substrate, in which each bed is subjected to a sequence comprising, in succession, an adsorption cycle, and a regeneration cycle,wherein each bed is out of phase with the cycle for all the other beds, provided that at least two beds are in the adsorption step at any time, wherein there is a lag time between the start of cycles in successive beds. 2. The method of claim 1, wherein said adsorption cycle comprises, introducing a fluid stream comprising a first component and a second component into the process fluid inlet the structured adsorbent bed, thereby producing an outlet stream rich in the first component and depleted in the second component, and enriching the nano-adsorbent with the second component, and removing the outlet stream from the process fluid outlet. 3. The method of claim 1, wherein said regeneration cycle comprises, introducing an electrical current into the porous electrical heating substrate of the structured adsorbent bed, thereby increasing the bed temperature for regenerating the structured adsorbent module and releasing the second component. 4. The method of claim 1, further comprising a cooling phase, comprising, introducing a cooling fluid stream into the process fluid inlet of the structured adsorbent bed, thereby cooling the regenerated adsorbent. 5. The method of claim 1, further comprising a re-pressurization phase before starting a new cycle. 6. The method of claim 1, wherein the lag time is C/N.
