Publication number: 20120195801Abstract: A reactor for carrying out catalytic reactions. The reactor includes a reactor component optionally arranged on a central rod in a reactor tube. The reactor component can have fluid ducts for directing fluid flow through the reactor. The fluid ducts are effective for increasing heat transfer in the reactor. The reactor component can further have a washer attached to a top or bottom surface for directing fluid flow.Type: ApplicationFiled: January 27, 2012Publication date: August 2, 2012Applicant: CATACEL CORPORATIONInventors: William A. Whittenberger, Gordon W. Brunson, Brian L. Davis, Todd A. Romesberg, Randall J. Bartos, Joseph W. Whittenberger

Publication number: 20080145284Abstract: A reactor including a monolith having a plurality of fins in an annular arrangement for receiving fluid flow through the reactor. The monolith is disposed within a generally cylindrical outer tube, and around a corrugated inner tube. The reactor includes a device for urging the monolith radially outward, so as to maintain contact between the monolith and the outer tube.Type: ApplicationFiled: December 13, 2007Publication date: June 19, 2008Applicant: CATACEL CORPORATIONInventors: William A. Whittenberger, David A. Becker, Randall J. Bartos

Patent number: 6948928Abstract: A catalytic combustor for a gas turbine includes a stack of metal strips, each strip having an inlet end and an outlet end. The inlet ends of both sides of the strip are uncoated, to limit the temperature and maintain rigidity of the strip at the inlet end. In one embodiment, both sides of the strip have a light-off band, coated with catalyst, and adjacent to the uncoated inlet band. One side of the strip (Side A) also includes at least one combustion band, while the other side (Side B) has no corresponding coated band. The strips are arranged such that Side A of a given strip inside the stack faces Side A of an adjacent strip, and Side B of a strip inside the stack faces Side B of an adjacent strip. The resulting structure prevents overheating of the combustor, maintains its rigidity, and reduces the pressure drop through the combustor.Type: GrantFiled: October 18, 2001Date of Patent: September 27, 2005Assignee: Catacel CorporationInventors: Richard C. Cornelison, William B. Retallick, William A. Whittenberger

Patent number: 6920920Abstract: A heat exchanger is made from a single piece of metal foil. The foil is coated with catalyst, corrugated with herringbone or skew corrugations, except along narrow flat areas near its edges, and folded back and forth upon itself. The folded metal structure is blocked off, except at regions near the flat areas, and enclosed in a container. A first gas stream flows into one set of folds, in a path which includes the flat areas and the channels formed by the corrugations. A second gas stream similarly flows into the other set of folds. The two streams are in thermal contact, but do not mix. The heat exchanger is especially useful in operating a catalytic fuel reformer, or in other applications involving catalytic processes. Alternative embodiments use straight corrugations to create straight channels that minimize the pressure drop through the heat exchanger.Type: GrantFiled: April 16, 2003Date of Patent: July 26, 2005Assignee: Catacel CorporationInventor: William A.

Patent number: 6783354Abstract: A combustion system for a gas turbine includes a steam reformer and a combustor connected in series. A portion of the incoming fuel is diverted to the steam reformer, the balance passing directly to the combustor. The effluent from the steam reformer, which effluent includes a significant amount of hydrogen, is combined with the unreformed fuel entering the combustor. The result is a hot combustion gas which contains very little NOx.Type: GrantFiled: May 2, 2003Date of Patent: August 31, 2004Assignee: Catacel CorporationInventor: William B. Retallick
