US Patent 10449520 Porous bodies with enhanced crush strength

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.
