Patent ID: 8728218

Claim:
A sorbent substrate for CO 2 capture, the sorbent substrate comprising: a plurality of sorbent filaments, each sorbent filament of the plurality of sorbent filaments comprising a matrix of sorbent material in which a plurality of through-channels are formed such that the plurality of through-channels extend through the matrix of sorbent material from a first end of each sorbent filament to a second end of each sorbent filament in an axial direction of each sorbent filament, wherein: the sorbent material is capable of adsorbing CO 2 from a gas stream passing through the plurality of through channels; the plurality of sorbent filaments are axially aligned with one another such that the plurality of through-channels of the plurality of sorbent filaments are substantially parallel with one another; and each sorbent filament of the plurality of sorbent filaments is bonded to at least one other sorbent filament.
