    摘要: A method and apparatus to treat a dried unfired article comprising a ceramic precursor composition substantially held together by a binder, to be resistant to binder soluble solvent based processing. The method includes depositing a fluid on the article surface, and polymerizing the deposited fluid to form a polymer thin layer on the surface. The fluid may be an aerosol, a vapor, a fog, a mist, a smoke, or combinations thereof. An apparatus to perform the method and an article resistant to binder soluble solvent based processing are also provided. The article can be an unfired honeycomb body that includes a dried composition of ceramic precursor substantially held together by a binder and a layer disposed on a surface of the unfired honeycomb body. The surface to be exposed in the green state to a binder soluble solvent and the layer protects the binder from solubilization by the solvent.

    摘要: A method of plugging a permeable porous cellular body (14) comprises: contacting the permeable porous cellular body (14) with a plugging mixture (100), the permeable porous cellular body (14) defining a plurality of channels (26); forcing the plugging mixture (100) into the plurality of channels (26) until a maximum, self-limiting, depth (114) of plugging mixture (100) is disposed within the plurality of channels (26); and maintaining a constant flow rate of the plugging mixture (100) into the plurality of channels until (26) a pressure on the plugging mixture (100) elevates to a predetermined pressure. Alternatively, the method comprises forcing the plugging mixture (100) into the plurality of channels (26) utilizing the application of a constant pressure over time until a maximum, self-limiting, depth (114) of the plugging mixture (100) is disposed within the plurality of channels (26); and maintaining the constant pressure applied to the plugging mixture (100) until flow of the plugging mixture (100) into the channels (26) decays from an initial flow rate to a predetermined flow rate.

    摘要: A pervaporation element includes a ceramic monolith having an array of parallel channels separated by porous channel walls extending along an axial length of the monolith, and a functional membrane coating a first plurality of the porous channel walls along the axial length of the monolith. The functional membrane functions to separate a fluid into a retentate portion and a permeate portion. The porous channel walls coated by the functional membrane define a plurality of discrete through segments, where each of the discrete through segments are separated from one another by a plurality of uncoated porous channel walls. Fluid entering the discrete through segments is separated into a retentate portion that exits in substantial portion through the discrete through segments and a permeate portion that exits the ceramic monolith radially outward through the uncoated porous channel walls and through a skin of the monolith.
