Abstract: Abstract The present invention is related to an improvement for a process for the generation of electrical power, wherein, in a cryogenic air separation unit, compressed air is distilled into an oxygen product and a waste nitrogen product, wherein at least a portion of the oxygen product is compressed and reacted with a carbonaceous fuel, in a gasifier or partial oxidation unit, to produce a synthesis (fuel) gas comprising carbon monoxide and hydrogen, wherein feed air is compressed in a gas turbine feed air compressor and subsequently saturated; wherein the synthesis gas is combusted with the saturated, compressed, gas turbine feed air in a combustor to produce a combustion gas, which passes through a transition piece and is then expanded in a gas turbine to generate work, wherein at least a portion of the generated work is used to drive the gas turbine feed air compressor and wherein at least another portion of the generated work is used to generate electricity.  The improvement is characterized by: (a) supplying at least a portion of the compressed air to the cryogenic air separation unit by withdrawing a portion of the compressed, gas turbine feed air from the gas turbine feed air compressor; and (b) utilizing at least a portion of the heat of compression of the oxygen product to heat water to saturate the compressed, gas turbine feed air.  The improvement can be further characterized by feeding at least a portion of the waste nitrogen product to an intermediate stage of the gas turbine feed air compressor, or by injecting at least a portion of the waste nitrogen product as a controllable inert gas coolant, diluent or mass flow enhancing component into at least one piece of equipment selected from the group consisting of the combustor, the transition piece and the gas turbine, or by utilizing at least a portion of heat inherent to the withdrawn portion of the compressed, gas turbine feed air from the gas turbine feed air compressor being fed to the cryogenic air separation unit to warm the portion of the oxygen product fed to the gasifier or partial oxidation unit.

Title: Method and apparatus for crosslinking individualized cellulose fibers
Inventor: HUNTER FRANK R
IPC: D04H1/58
Filed: 1993-01-13
Abstract: An apparatus is disclosed for preparing a quantity of individual treated fibers from one or more fiber mats. The apparatus comprises a fiber treatment zone, and a conveyor for conveying each mat through the fiber treatment zone. In the treatment zone each mat is impregnated by an applicator with a treatment material, such as a crosslinking substance, and conveyed directly to an attrition device. The attrition device fiberizes the mats to form a fiber output having a low nit level, such as no more than about three, and a dryer both dries the fiber output and cures the crosslinking substance. The fiberizer is configured to minimize the accumulation of fiber at locations therein. Fiber is transported from the attrition device to the dryer at a high velocity under reduced pressure to promote drying. A heated retention bin is provided after drying to increase curing time in the system. A thermobonding agent may be added to the dried and cured fibers to enhance the wet strength of webs made from the fiber.

Title: Catalytic combustion process using supported palladium oxide catalysts
Inventor: KENNELLY TERESA
IPC: F23C13/00
Filed: 1993-03-01
Abstract: A process for operating a palladium oxide-containing catalytic combustor is useful, e.g., for powering a gas turbine. The palladium oxide is supported on a metal oxide such as alumina, lanthanide metal oxide-modified alumina, ceria, titania or tantalum oxide.  The method involves maintaining control of the temperature within the combustor in such a manner as to insure the presence of palladium oxide. By maintaining the temperature below the decomposition onset temperature of palladium oxide (which is catalytically active for catalytic combustion) into metallic palladium (which is catalytically inactive) deactivation of the catalyst is avoided and high catalytic activity is retained. Regeneration of catalyst following inactivation resulting from an over-temperature is accomplished by using a heat soak in a regeneration temperature range which varies depending on the particular metal oxide used to support the palladium oxide.
