Publication number: 20120277097Abstract: A gas mixture preheated to high temperatures using an oxy-fuel, an oxygen-enriched air-fuel or an air-fuel burner is used to devolatilize and partially oxidize carbonaceous feedstock, thereby producing an active residual char that can be used in applications utilizing activated carbon. Use of hot gas and ground carbonaceous feedstock allows the equipment to be minimized, thereby allowing the activated carbon to be produced at or near points of use, for example the production of activated char at or near utility boilers for use in the reduction of mercury emissions from flue gas streams.Type: ApplicationFiled: February 21, 2012Publication date: November 1, 2012Inventors: Lawrence E. Bool, III, Chien-Chung Chao, Mark K. Weise, Jurron L.D. Bradley

Patent number: 8196387Abstract: An apparatus for generating electrical power in which a synthesis gas stream generated in a gasifier is partially oxidized, expanded and thereafter, is combusted in an oxygen transport membrane system of a boiler. The combustion generates heat to raise steam to in turn generate electricity by a generator coupled to a steam turbine. The resultant flue gas can be purified to produce a carbon dioxide product.Type: GrantFiled: November 17, 2010Date of Patent: June 12, 2012Assignee: Praxair Technology, Inc.Inventors: Minish Mahendra Shah, Aqil Jamal, Raymond Francis Dmevich, Bart Antonie van Hassel, Gervase Maxwell Christie, Hisashi Kobayashi, Lawrence E.

Patent number: 6981994Abstract: This invention is directed to a process for increasing production of product that is formed in a reactor having a combustion section in which fuel is burned to produce heat to drive an endothermic reaction occurring within a reaction section. Production is increased by adding supplemental oxygen to air or other oxygen containing gas used to support combustion in the combustion section, thereby to generate more heat to support an increase in the endothermic reaction. Additionally, supplemental oxygen can be introduced into the reaction section to partially oxidize a reactant to generate heat and to allow an increase in the production of the product. Supplemental oxygen may be added directly to the steam-methane mixture, or to the combustion air.Type: GrantFiled: August 21, 2002Date of Patent: January 3, 2006Assignee: Praxair Technology, Inc.Inventors: Raymond Francis Drnevich, Gary Wayne Fenner, Hisashi Kobayashi, Lawrence E. Bool, III

Patent number: 6702570Abstract: A method of firing a heat consuming device such as a boiler or furnace in which an oxygen transport membrane is integrated with the device such that part of the permeated oxygen supports an initial combustion to heat the incoming air to the oxygen transport membrane system. A remaining portion of the oxygen after having been diluted with flue gases from the boiler supports a secondary combustion of fuel within the heat consuming device.Type: GrantFiled: June 28, 2002Date of Patent: March 9, 2004Assignee: Praxair Technology Inc.Inventors: Minish Mahendra Shah, Lawrence E.
