Abstract:
1. A natural gas adsorption device, comprising: at least one porous, flexible container comprising at least one porous layer, the porous layer having an average pore diameter and is permeable to natural gas, a natural gas adsorption material at least partially disposed in the container, the material having a volume average diameter larger than the average pore diameter of the container, and a storage tank having an opening, the tank enclosing the container and the natural gas adsorption material, wherein the container comprises a material having a melting temperature of at least about 85° C. or a material having a glass transition temperature of at least about 85° C., and wherein the container comprises a material selected from the group consisting in fibrous or expanded film form, of glass, polyesters, polyacrylates, polymethacrylates, epoxy polymers, polyimides, polyvinyl alcohols, polyurethanes, polyacrylnitriles, polyolefins, polyphenylene sulfides, nylons, celluloses, polycarbonates, polyvinylidene fluorides, perfluoroalkoxy Polymers, fluorinated ethylene-propylene polymers, polytetrafluoroethylenes, polyamides, and copolymers thereof, and wherein the porosity of the container is formed by the gaps between the fibrous form of said materials in woven or non-woven form, or by expanding the film form of said materials.
