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

Methods of plugging a permeable porous cellular body

A porous ceramic honeycomb body () including intersecting walls that form channels () extending axially from a first end face to a second end face and layered plugs () comprised of a first layer () disposed on channel walls and a second layer () disposed inward toward an axial center of each respective channel on the first layer. The plugs seal at least one of a first portion of the channels at the first end face and a second portion of channels at the second end face of the porous ceramic honeycomb body.

Disclosed is a honeycomb support structure comprising a honeycomb body and an outer layer or skin formed of a cement that includes an inorganic filler material having a first coefficient of thermal expansion from 25 C to 600 C and a crystalline inorganic fibrous material having a second coefficient of thermal expansion from 25 C to 600 C. Skin cement composition controls level of cement liquid/colloid components, for example water, colloidal silica, and methylcellulose migration into the substrate during the skin application process to form barrier to skin wetting and staining during the washcoating process.

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.

Cellular ceramic article and method for manufacturing the same

The present invention pertains to a pervaporation membrane process for the separation of high octane fuel components from a gasoline feed stream comprising feeding a mixed phase vapor-liquid feed to a cyclone separation means to separate the liquid from the vapor, then sending the saturated vapor to the membrane, thereby extending the useful life of the membrane.

Membrane separation process using mixed vapor-liquid feed

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.

Partition fluid separation

Cellular ceramic articles are manufactured from a green cellular ceramic body that includes a binder material and a plurality of channels. At least one of the channels is coated with a slurry that includes a green coating composition and a solvent to form a coating layer. The binder material is insoluble in the solvent.
