First Claim
Patent Images
1. A removable adsorbent cartridge for removal of gaseous contaminants comprising:
- a plurality of parallel, non-wound adsorbent sheets, mechanically spaced so as to allow gas flow between each sheet in the plurality, wherein each adsorbent sheet is formed from a mixture comprising a polymer and an adsorbent, wherein the sheets are spaced by ribs protruding from each sheet and molded directly out of the adsorbent sheet; and
one or more fasteners disposed within the adsorbent cartridge, wherein the one or more fasteners secures the plurality of said sheets together;
wherein the cartridge does not further comprise a rigid shell encasing the cartridge; and
wherein the cartridge is self-supporting without the need for external support or gluing or fusing the sheets together.

21. A gaseous contaminant removal system comprising:
-
(1) a removable adsorbent cartridge comprising; a plurality of parallel, non-wound adsorbent sheets, mechanically spaced so as to allow gas flow between each sheet in the plurality, wherein each adsorbent sheet is formed from a mixture comprising a polymer and an adsorbent, wherein the sheets are spaced by ribs protruding from each sheet and molded directly out of the adsorbent sheet; and one or more fasteners, wherein the one or more fasteners secures the plurality of said sheets together;
wherein the cartridge does not further comprise a rigid shell encasing the cartridge; and(2) a canister comprising; an inlet through which gas can flow to contact the adsorbent cartridge; an outlet for gas flow; and a plurality of support structures disposed on the interior walls of the canister, which provide mechanical stability to the adsorbent cartridge by restricting movement of the cartridge within the canister during use; wherein the cartridge is placed in the canister such that the gas flow from the inlet of the canister can flow between the adsorbent surfaces in said cartridge.
