Appl. No.:

12/121139

Inventors:

Kenneth Wesley Hamby - The Woodlands TX, US
James Brian Kelly - La Jolla CA, US
Timothy Joseph Kuhn - Perrysburg OH, US

Assignee:

Tellus Technology, LLC - San Diego CA

International Classification:

C01D 3/00
B32B 5/16
B22F 3/00
B01F 13/00

US Classification:

4234491, 4234498, 428402, 425222, 366342

Abstract:

A pyrolysis process is provided. The process includes the steps of: depositing a quantity of waste into a porous container, the porous container adapted to allow a convective stream of substantially anaerobic gas to flow therethrough; inserting the porous container into a pyrolysis thermal processor; sealing the thermal processor; circulating the convective stream of gas through the pyrolysis thermal processor; heating the waste according to a first time-temperature profile to pyrolyze the waste and form a carbonaceous char; and cooling the carbonaceous char by circulating the convective stream of gas through a cooler. An oil product and a gaseous hydrocarbon product are produced during the pyrolysis. The carbonaceous char is further processed to form a carbon black product and a recyclable metal product.

US Patent:

51634163, Nov 17, 1992

Filed:

Aug 1, 1991

Appl. No.:

7/739081

Inventors:

Thomas J. Schultz - Maumee OH
Timothy J. Kuhn - Toledo OH

Assignee:

Gas Research Institute - Chicago IL

International Classification:

F24C 304

US Classification:

126 92R

Abstract:

A standard atmosphere furnace constructed of a steel casing formed as a cylinder with fibrous insulation attached is operated as a vacuum furnace. A plurality of radiant, fuel-fired ceramic heat tubes positioned in a centered but circumferentially spaced arrangement provides heat input to the furnace to permit it to operate at high, vacuum associated temperatures. The ceramic tubes are vacuum sealed to the furnace case by an elastomer seal/water jacket arrangement which uses an outboard clamp arrangement to establish a ceramic-to-metal contact to permit thermal cooling and prevent tube-flange movement so that the integrity of the elastomer seal can be maintained. In addition, an articulated joint connector is provided so that the tube can be supported in a pivotable manner permitting thermal movement while reducing tube stress to prolonged tube life.

7/146195

Inventors:

Timothy J. Kuhn - Toledo OH

Assignee:

Gas Research Institute - Chicago IL

International Classification:

F27B 914
F27B 512

US Classification:

432126

Abstract:

A retractable, roller hearth for use in an industrial heat treat furnace is disclosed whereby the alloy rollers are retracted from their load bearing position when the furnace heat treat processes are underway thus maintaining the rated load capacity of the furnace. A plurality of guided rail support posts and guided, sealed lift posts accurately assure straight line vertical motion of the refractory base enabling contact between fibrous rope seals to seal the hearth from the cooler, lower portions of the furnace when the hearth is in a raised position.

Abstract:

A continuous process and apparatus for treating dried coal and coal char to promote passivation of the reactive carbon particles by forming a protective oxide coating and simultaneously adding moisture to rehydrate said particles. The passivation process is conducted in a novel apparatus providing for the staged control of the reaction temperature and the staged introduction of both oxygen and moisture. The fluidized bed apparatus has internal in-bed cooling means embedded within the fluidized coal or coal char particles so as to remove the heat energy as it is released by virtue of the exothermic passivation reactions.
