Abstract:
1. An integrated, self-supporting adsorbent cartridge assembly for removing carbon dioxide contaminant, comprising: (a) an adsorbent cartridge, comprising an adsorbent sheet wound into a roll, wherein the adsorbent sheet is formed from a mixture comprising a polymer and an adsorbent, wherein the sheet is spaced to form multiple layers by ribs protruding from the sheet and molded directly out of the adsorbent sheet, wherein said sheet wound into a roll comprises a first open end face, a second open end face, and an outer portion; wherein: the adsorbent comprises calcium hydroxide or lithium hydroxide; the adsorbent cartridge does not comprise a rigid outer housing; the open end faces are at opposite ends of the cartridge; said layers are disposed orthogonally with respect to the open end faces; and said layers are mechanically spaced so as to allow gas flow between said layers; and (b) an end cap secured around said first open end face, wherein said end cap allows gas flow through said first open end face, comprising: an outer sleeve circumscribing the outer portion of one end of the cartridge adjacent to said first open face; wherein said outer sleeve has a portion protruding beyond said one end of the cartridge; and the protruding portion comprises an inner surface; wherein the assembly has mechanical integrity during transportation and installation.
