a polymer binder or other chemical binder for maintaining the integrity of the briquette units it is noted that surprisingly such binder additives are not required for practice of the present invention not wishing to be bound by any particular theory it is noted that in certain embodiments binder materials can degrade adsorbent performance of sorbent briquette units and thus it is useful for the compressed particulate matter such as compressed adsorbent granules or compressed adsorbent powder to derive external support to maintain its form from a supportive envelop liner shell sheath vessel or membrane any appropriate material known in the art of any appropriate thickness for providing mechanical support for compressed particulate matter is appropriate for the liner or open vessel of the briquette unit in some embodiments the liner or open vessel includes a good heat conductor such as for example a metal or heat conducting plastic exemplary material include but are not limited to aluminum carbon steel stainless steel titanium magnesium zinc and copper in some embodiments the liner or open vessel includes a poor or moderate heat conductor laminated with a material of higher heat conductivity furthermore it is noted that the principles of the present invention can be applied to any compressed gas adsorbing particulate matter exemplary gas adsorbing materials include but are not limited to carbon such as activated carbon zeolite clays alumina and silica gel referring now to the drawings fig2 provides a diagram of an exemplary one volume storage tank for storage of adsorbed gas such as adsorbed natural gas although the exemplary storage tank 1 illustrated in fig2 is a one volume tank this is by no means a limitation of the present invention and in some embodiments a multicell tank storage tank is provided there is no particular.
