Abstract
Official abstract text for this publication.
A method for making a porous inorganic membrane comprises using a mixture of an inorganic material, organic polymer particles and a solvent to form a slurry. The particles are non-spherical. The method further comprises distributing the slurry onto a surface, drying the slurry to remove the solvent and firing the dried slurry to produce the porous inorganic membrane. Examples of organic polymer particles include particles of acrylic. A substrate comprises a support with a porous inorganic membrane disposed on the support. The inorganic membrane has an average thickness of from about 0.5 micron to about 30 microns, a porosity of from about 30% to about 65%, a median pore size (d50) of from about 0.01 micron to about 1 micron, and a value of (d90−d10)/d50 less than about 2, as measured by mercury porosimetry. An example of a support includes an inorganic porous support.
First claim
Opening claim text (preview).
What is claimed is: 1. A substrate, comprising: a support; and a porous inorganic membrane disposed on a surface of the support, the porous inorganic membrane having (i) an average thickness of from about 0.5 micron to about 30 microns, (ii) a porosity of from about 30% to about 65%, (iii) a median pore size (d50) of from about 0.01 micron to about 1 micron, (iv) a value of (d90−d10)/d50 less than about 2, as measured by mercury porosimetry, and (v) a single modal pore size distribution. 2. The substrate of claim 1 wherein the porous inorganic membrane has an average thickness of from about 1 micron to about 10 microns. 3. The substrate of claim 1 wherein the support is an inorganic porous support. 4. The substrate of claim 3 wherein the inorganic porous support is in the form of a honeycomb monolith. 5. The substrate of claim 3 wherein the inorganic porous support comprises a ceramic comprising cordierite, alpha-alumina, mullite, aluminum titanate, titania, zirconia, ceria or combinations thereof. 6. The substrate of claim 1 , wherein the porous inorganic membrane comprises a porosity from about 48% to about 65%. 7. The substrate of claim 1 , wherein the support is an inorganic porous support comprising a median pore size greater than the median pore size of the porous inorganic membrane. 8. The substrate of claim 1 , wherein the porous inorganic membrane comprises a porosity of from about 44% to about 65%.
