Abstract: A precursor mixture for producing a porous body, wherein the precursor mixture comprises: (i) at least one milled alpha alumina powder having a particle size of 0.1 to 6 microns, (ii) non-silicate powder that functions as a binder of the alpha alumina powders, and (iii) at least one burnout material having a particle size of 1-10 microns and a decomposition temperature of less than 550° C., with the proviso that a burnout material having a decomposition temperature of 550° C. or greater is excluded from the precursor mixture.

Abstract: A porous body with enhanced fluid transport properties and crush strength is provided. The porous body includes the porous body includes at least 80 percent alpha alumina and having a pore volume from 0.3 mL/g to 1.2 mL/g, a surface area from 0.3 m2/g to 3.0 m2/g, and a pore architecture that provides at least one of a tortuosity of 7 or less, a constriction of 4 or less and a permeability of 30 mdarcys or greater, wherein the porous body is a cylinder comprising at least two spaced apart holes that extend through an entire length of the cylinder. The porous body has a flat plate crush strength improved by more than 10% over a porous body cylinder having a same outer diameter and length, but having only a single hole.
