Abstract
A channelized sorbent material comprises porous sorbent particles characterized by an average pore diameter. Each sorbent particle has at least one interior channel of an average transverse dimension (i.e. transverse diameter) that is at least ten times larger than the average pore diameter of the porous sorbent particle. The interior channel may constitute a single cylindrical through-bore in the sorbent particle, or alternatively, an array of intersecting or non-intersecting channels. The porous sorbent particles preferably comprise bead activated carbon particles. Such channelized sorbent material is particular useful as sorbent media in an adsorption-desorption apparatus for storage and dispensing of a sorbable fluid.
Claims34
A solid-phase porous sorbent material having an average pore diameter, wherein said solid-phase porous sorbent material comprises sorbent particles having at least one interior channel therein, and wherein said interior channel has an average transverse dimension at least one order of magnitude (10×) larger than said average pore diameter of said solid-phase porous sorbent material.
An adsorption-desorption apparatus, for storage and dispensing of a sorbable fluid, said apparatus comprising:
- (a) a storage and dispensing vessel constructed and arranged for holding a solid-phase porous sorbent material, and for selectively flowing fluid in and out of said vessel;
- (b) a channelized solid-phase porous sorbent material, disposed in said storage and dispensing vessel at an interior gas pressure, wherein said solid-phase porous sorbent material has an average pore diameter and comprises sorbent particles having at least one interior channel, and wherein said interior channel has an average transverse dimension at least one order of magnitude (10×) larger than the average pore diameter of said solid-phase porous sorbent material;
- (c) a sorbable fluid adsorbed on said solid-phase porous sorbent material;
- and
- (d) a dispensing assembly coupled in gas flow communication with the storage and dispensing vessel.
A channelized sorbent material having an average pore diameter, wherein said channelized sorbent material comprises sorbent particles having one or more interior channels, and wherein said interior channels have a transverse diameter at least one order of magnitude (10×) larger than the average pore diameter of said channelized sorbent material.
