Patent number: 7304013Abstract: Bulk and supported catalysts are prepared from an aqueous slurry containing a catalytically active material and a binder. The slurry is either coated onto a support and dried to form a porous, high surface area phase containing the catalytically active material, or reduced to a paste-like consistency, molded and dried to form a bulk catalyst. The processes and catalysts may be employed in various catalytic chemical processes to achieve high effectiveness factor of the catalytically active material while achieving a lower pressure drop.Type: GrantFiled: June 30, 2003Date of Patent: December 4, 2007Assignee: Corning IncorporatedInventors: William P.

Patent number: 6916943Abstract: A process of making a supported catalyst includes steps of preparing a washcoat containing a mixture of hydrolyzed silicon alkoxide and a filler, depositing the washcoat on a surface of a solid support, drying the washcoat deposited on the surface of the solid support to form a coating on the surface of the solid support, and distributing a metal catalyst on the coating. The resulting supported catalyst may be used in a reaction vessel, such as a fixed bed reactor, for effecting a catalytic reaction, such as catalytic hydrogenation of an edible oil. The washcoatings can be formulated to provide a viscous composition that can be applied to form a thick coating on a substrate. The dried washcoatings exhibit excellent stability, cohesive layering strength, and adhesive strength between the coating and a substrate.Type: GrantFiled: December 16, 2002Date of Patent: July 12, 2005Assignee: Corning IncorporatedInventors: William P.

Patent number: 6004896Abstract: A method for improving the adsorption properties of a hydrocarbon adsorber involves contacting a molecular sieve hydrocarbon adsorber at ambient temperature with an agent for modifying the acid sites of the molecular sieve to impregnate the molecular sieve with the agent. The average pore diameter of the intracrystalline porosity of the molecular sieve is about 3 to 20 angstroms. The agent has an anionic portion which is retained within the structure of the molecular sieve. The modified molecular sieve has the ability to retain adsorbed hydrocarbons at higher temperatures than the unmodified molecular sieve. The acid-modified molecular sieve can be used to remove hydrocarbons from a hydrocarbon-containing stream. The hydrocarbon-containing stream is passed through the modified adsorber at atmospheric pressure at a temperature ranging from room temperature to about 150.degree. C. to cause adsorption and retention of the hydrocarbons.Type: GrantFiled: May 4, 1998Date of Patent: December 21, 1999Assignee: Corning IncorporatedInventor: William P. Addiego

Patent number: 6001320Abstract: A method for improving the adsorption properties of a hydrocarbon adsorber which involves contacting a molecular sieve hydrocarbon adsorber with an agent for modifying the acid sites of the molecular sieve to impregnate the molecular sieve with the agent. The resulting acid-modified molecular sieve has the ability to retain adsorbed hydrocarbons at higher temperatures than the molecular sieve in the un-modified state. The acid-modified molecular sieve can be used to remove hydrocarbons from a workstream. The workstream is passed through the modified adsorber at atmospheric pressure at a temperature ranging from room temperature to about 150.degree. C. to cause adsorption and retention of the hydrocarbons. The adsorbed hydrocarbons can then be desorbed at a higher temperature than would otherwise occur with an unmodified adsorber.Type: GrantFiled: December 19, 1997Date of Patent: December 14, 1999Assignee: Corning IncorporatedInventor: William P. Addiego

A method is disclosed for producing the material which comprises forming a precursor material by wet-mixing a phosphate yielding species and an aluminum oxide yielding species which can be aluminum oxide, aluminum hydroxylated oxides, aluminum hydroxide, aluminum alkoxides, and combinations thereof, in amounts sufficient to result in an AlPO.sub.4 content of about 3 to 12 percent by weight in the phosphate-Al.sub.2 O.sub.3, drying and heat-treating the precursor material at a temperature and for a time sufficient to form the phosphate- Al.sub.2 O.sub.3. The material is used as a support for catalyst metals.Type: GrantFiled: August 12, 1992Date of Patent: November 9, 1993Assignee: Corning IncorporatedInventors: William P. Addiego, Irwin M.
