Abstract: A porous ceramic body is provided for a variety of applications. The porous ceramic body includes mesocrystals of alumina such as, for example, alpha alumina. Porous alpha alumina bodies containing the mesocrystal microstructure can provide enhanced activity and catalyst lifetime when the same is used as a carrier for a silver-based ethylene oxide catalyst.

Abstract: A porous body is provided with enhanced fluid transport properties that is capable of performing or facilitating separations, or performing reactions and/or providing areas for such separations or reactions to take place. The porous body includes at least 80 percent alpha alumina and has a pore volume from 0.3 mL/g to 1.2 mL/g and a surface area from 0.3 m2/g to 3.0 m2/g. The porous body further includes a pore architecture that provides at least one of a tortuosity of 7.0 or less, a constriction of 4.0 or less and a permeability of 30 mdarcys or greater. The porous body can be used in a wide variety of applications such as, for example, as a filter, as a membrane or as a catalyst carrier.

Abstract: A precursor mixture for producing a porous body, wherein the precursor mixture comprises: (i) milled alpha alumina powder having a particle size of 0.1 to 6 microns, (ii) boehmite powder that functions as a binder of the alpha alumina powders, and (iii) burnout materials having a particle sizes of 1-10 microns. In some embodiments, an unmilled alpha alumina powder having a particle size of 10 to 100 microns is also included in said precursor mixture. Also described herein is a method for producing a porous body in which the above-described precursor mixture is formed to a given shape, and subjected to a heat treatment step in which the formed shape is sintered to produce the porous body.

Abstract: Oxalic acid is employed in a precursor mixture containing at least one milled alpha alumina powder having a particle size of 0.1 to 6 microns, boehmite powder that functions as a binder of the alpha alumina powders, and at least one burnout material having a particle size of 1-10 microns to provide a porous body having enhanced pore architecture in which extrusion cracks can be reduced. The presence of oxalic acid in such as precursor mixture can reduce and even eliminate NOx emission during a high temperature heat treatment process.
