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 method for lowering the sodium content of different carriers which may have different physical properties as well as varying degrees of sodium is provided. The method, which lowers the sodium content from the surface, subsurface as well as the binding layer of the carrier, includes contacting a carrier with water. A rinse solution is recovered from the contacting. The rinse solution includes leached sodium from the carrier. The sodium content in the rinse solution is then determined. The contacting, recovering and determining are repeated until a steady state in the sodium content is achieved.

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.

Abstract: A silver impregnation solution comprising: (i) silver ions, (ii) a silver concentration enhancer selected from at least one ammonium salt having an anionic component that is thermally decomposable; or at least one amino acid, or a combination thereof, (iii) at least one organic amine; and (iv) water; wherein said components (i)-(iii) are dissolved in said impregnation solution, and oxalic acid may or may not be included. The silver impregnation solution can achieve significantly higher silver concentrations, including at least or above 33, 34, or 35 wt %. Methods for producing a silver catalyst by silver impregnation of a refractory support followed by calcination are also described. The resulting silver catalysts possess high silver loadings of typically at least 17, 18, or 19 wt %.
