Abstract:
Disclosed is a ceramic honeycomb structure comprising a honeycomb body and a multilayered outer layer formed of a thick core layer applied and rapidly dried and a thin clad layer dried more gently to form a crack free dual skin layer. The core layer may have properties that are closer to those of the ceramic honeycomb body in service than the clad layer that may provide a tough outer shell to withstand handling and assembly.
Abstract:
Cyclonic separation devices and fluid stream separating apparatuses incorporating cyclonic separation devices are described. A cyclonic separation device may include an exterior housing having an exterior cylindrical portion and an exterior conical portion extending from the exterior cylindrical portion and an interior housing having an interior cylindrical portion and an interior conical portion extending from the interior cylindrical portion. The interior housing is positioned relative to the exterior housing to form a circulating chamber. The cyclonic separation device also includes a fluid inlet coupled to the exterior housing, where the fluid inlet positioned to inject a fluid stream into the circulating chamber at an orientation generally tangential to the cylindrical portions of the exterior housing and the interior housing. The cyclonic separation device further includes a low-density outlet coupled to at least one of the exterior conical portion or the interior conical portion.

An article comprising a plurality of intersecting walls having outer surfaces that define a plurality of cells extending from one end to a second end, wherein the walls forming each cell in a first subset of cells are covered by a barrier layer to form a plurality of heat exchange flow channels, and wherein the walls forming each cell in a second subset of cells different from the first subset of cells, comprise a CO
Abstract:
Un método y sistema para secar el revestimiento sin grietas y de alta resistencia que incluye un aglutinante inorgánico de un tamaño de partículas promedio (D50) en una escala de 10 nm y 700 nm en un cuerpo cerámica porosa; el método incluye soportar el cuerpo de panal sobre una cara de extremo de tal manera que los canales axiales y la periferia exterior son sustancialmente verticales; un gas se hace fluir más allá del cuerpo de panal sustancialmente paralelo a la dirección del canal axial, sustancialmente igual alrededor a la periferia exterior del revestimiento, para secar uniformemente el revestimiento para formar un revestimiento parcialmente seco bajo condiciones moderadas; después, el revestimiento parcialmente seco puede secarse más severamente teniendo en el revestimiento sin grietas y de alta resistencia rápidamente seco.
Abstract:
High volumetric-efficiency thermally integrated systems for captur¬ ing a target gas from a process gas stream include a monolithic body (10) and a distribution system. The monolithic body (10) includes a first plurality of channels (25) and a second plurality of channels (35) each having sorbent surfaces that reversibly adsorb the target gas. The channels are in thermal communication such that heat from an exothermic adsorption of target gas in one plurality of channels is used by an endothermic desorption of target gas from the other plu¬ rality of channels. Methods for separating a target gas from a process gas stream include switching the high volumetric-efficiency thermal¬ ly integrated systems between a first state and a second state. In the first state, the first plurality of channels (25) undergoes desorption while the second (35) undergoes adsorption. In the second state, the second plurality of channels (35) undergoes desorption while the first plurality (25) undergoes adsorption.
Abstract:
Systems for and methods of drying a wet skin (18) of a wet skinned ceramic ware (10) are disclosed. The wet skinned ceramic ware (10) includes a dry interior web (26) with an outer surface (16). The wet skin (18) is disposed on the outer surface (16) of the dry interior web (26). The method includes generating an airstream (212) and then directing the airstream (212) through a first end of the wet-skinned ceramic ware only through an annular portion (26A) of the interior web (26) that is adjacent the outer surface (16) of the interior web (26). The flow of the airstream (212) through the annular portion (26A) of the interior web (26) causes moisture in the wet skin (18) to migrate inwardly toward the interior web (26). The moisture is removed from the annular portion (26A) of the interior web (26) when the airstream (212) exits a second end of the ceramic ware, thereby drying the skin (18) from the inside out of the wet-skinned ceramic ware (10).
Abstract:
An article comprising a plurality of intersecting walls having outer surfaces that define a plurality of cells extending from one end to a second end, wherein the walls forming each cell in a first subset of cells are covered by a barrier layer to form a plurality of heat exchange flow channels, and wherein the walls forming each cell in a second subset of cells different from the first subset of cells, comprise a CO2 sorbent and form reaction flow channels. Heat exchange flow channels allow quick and uniform heating and cooling of the sorbent body. The article may be useful, for example, for removing CO2 from a gas stream.
