Abstract
Embodiments for a tubular ceramic-carbonate dual-phase membrane and methods for manufacturing the tubular ceramic-carbonate dual-phase membrane are disclosed.
Claims15
A tubular dual-phase membrane comprising:
- a tubular-shaped body comprising:
- an outer support layer comprising a first ceramic material that is non-wettable with carbonate;
- a thin inner layer bonded to the outer support layer made from a second ceramic material that is wettable with carbonate;
- and
- a channel defined by the thin inner layer, wherein the channel is in communication with a proximal opening at a first end of the tubular body and a distal opening at a second end of the tubular body.

A tubular dual-phase membrane comprising:
- a tubular-shaped body comprising:
- a solid porous ceramic phase made from a material that is non-wettable with carbonate and serves as an oxygen ion conductor;
- a molten carbonate phase made from a material that comprises carbonate;
- and
- a channel defined by the molten carbonate phase, wherein the channel is in communication with a proximal opening at a first end of the tubular-shaped body and a distal opening at a second end of the tubular-shaped body

A method for manufacturing a tubular dual-phase membrane comprising:
- spinning a first suspension in a centrifuge, wherein the first suspension comprises bismuth-yttria-smaria (“BYS”) poured into a container, wherein the BYS forms an outer layer after being spun in the centrifuge;
- spinning a second suspension in a centrifuge, wherein the second suspension comprises samaria doped ceria (“SDC”), wherein the SDC forms an inner layer that bonds with the outer layer to form a substantially tubular-shaped body after being spun in the centrifuge;
- removing the substantially tubular-shaped body from the container;
- and
- immersing the substantially tubular-shaped body in molten carbonate, wherein the molten carbonate is wettable with the inner layer and non-wettable with the second layer such that the molten carbonate bonds with the inner layer.
