Patent number: 6492290Abstract: This invention presents a new class of multicomponent metallic oxides which are particularly suited toward use in fabricating components used in processes for producing syngas. The non-stoichiometric, A-site rich compositions of the present invention are represented by the formula (LnxCa1−x)y FeO3−&dgr;wherein Ln is La or a mixture of lanthanides comprising La, and wherein 1.0>x>0.5, 1.1≧y>1.0 and &dgr; is a number which renders the composition of matter charge neutral. Solid-state membranes formed from these compositions provide a favorable balance of oxygen permeance and resistance to degradation when employed in processes for producing syngas. This invention also presents a process for making syngas which utilizes such membranes.Type: GrantFiled: August 22, 2000Date of Patent: December 10, 2002Assignee: Air Products and Chemicals, Inc.Inventors: Paul Nigel Dyer, Michael Francis Carolan, Darryl Butt, Rene Hendrick Elias Van Doorn, Raymond Ashton Cutler

Patent number: 6114400Abstract: Natural gas or other methane-containing feed gas is converted to a C.sub.5 -C.sub.19 hydrocarbon liquid in an integrated system comprising an oxygenative synthesis gas generator, a non-oxygenative synthesis gas generator, and a hydrocarbon synthesis process such as the Fischer-Tropsch process. The oxygenative synthesis gas generator is a mixed conducting membrane reactor system and the non-oxygenative synthesis gas generator is preferably a heat exchange reformer wherein heat is provided by hot synthesis gas product from the mixed conducting membrane reactor system. Offgas and water from the Fischer-Tropsch process can be recycled to the synthesis gas generation system individually or in combination.Type: GrantFiled: September 21, 1998Date of Patent: September 5, 2000Assignee: Air Products and Chemicals, Inc.Inventors: Shankar Nataraj, Steven Lee Russek, Paul Nigel Dyer

Patent number: 6090265Abstract: An electrochemical device for separating oxygen from an oxygen-containing gas comprises a plurality of planar ion-conductive solid electrolyte plates and electrically-conductive gas-impermeable interconnects assembled in a multi-cell stack. Electrically-conductive anode and cathode material is applied to opposite sides of each electrolyte plate. A gas-tight anode seal is bonded between the anode side of each electrolyte plate and the anode side of the adjacent interconnect. A regulating electrode, applied to the anode side of each electrolyte plate between the anode seal and the edge of the anode, eliminates anode seal failure by maintaining the 24-hour anode seal power density below about 1.5 .mu.W/cm.sup.2. A gas-tight seal is applied between the cathode sides of each electrolyte plate and the adjacent interconnect such that the anode and cathode seals are radially offset on opposite sides of the plate.Type: GrantFiled: August 28, 1998Date of Patent: July 18, 2000Assignee: Air Products and Chemicals, Inc.Inventors: Stuart Adler, Robin Edward Richards, Paul Nigel Dyer

Patent number: 5750279Abstract: An electrochemical device is disclosed comprising a plurality of planar electrolytic cells connected in series, each cell having an oxygen ion-conducting electrolyte layer, an anode layer and a cathode layer associated with the electrolyte layer, electrically conductive interconnect layers having gas passages situated therein for transporting gaseous streams, which interconnect layers electrically connect the anode layer of each electrolytic cell to the cathode layer of an adjacent planar cell, and sealing means positioned between the interconnect layers and the electrolytic cells to provide a gas-tight seal therebetween. The configuration of the interconnect layer and the placement of the seal means provides a separation between the seal and the conductive pathway of electrons between the anode layer and cathode layer which prevents corrosion or deterioration of the seal.Type: GrantFiled: May 9, 1994Date of Patent: May 12, 1998Assignee: Air Products and Chemicals, Inc.Inventors: Michael Francis Carolan, Paul Nigel Dyer, Eric Minford, Steven Lee Russek, Merrill Anderson Wilson, Dale M.

Patent number: 5683797Abstract: The present invention is a method for manufacturing inorganic membranes which are capable of separating oxygen from oxygen-containing gaseous mixtures. The membranes comprise a porous composite of a thin layer of a multicomponent metallic oxide which has been deposited onto a porous support wherein the pores of the multicomponent metallic oxide layer are subsequently filled or plugged with a metallic-based species. The inorganic membranes are formed by depositing a porous multicomponent metallic oxide layer onto the porous support to form a porous composite having a network of pores capable of transporting gases. The network of pores are plugged or filled by organometallic vapor infiltration to form an inorganic membrane having essentially no through porosity.Type: GrantFiled: March 19, 1996Date of Patent: November 4, 1997Assignee: Air Products and Chemicals, Inc.Inventors: Michael Francis Carolan, Paul Nigel Dyer, Stephen Mark Fine, Alexander Makitka, III, Robin Edward Richards, Leslie Errol Schaffer

Patent number: 5681373Abstract: Planar solid-state membrane modules for separating oxygen from an oxygen-containing gaseous mixture which provide improved pneumatic and structural integrity and ease of manifolding. The modules are formed from a plurality of planar membrane units, each membrane unit which comprises a channel-free porous support having connected through porosity which is in contact with a contiguous dense mixed conducting oxide layer having no connected through porosity. The dense mixed conducting oxide layer is placed in flow communication with the oxygen-containing gaseous mixture to be separated and the channel-free porous support of each membrane unit is placed in flow communication with one or more manifolds or conduits for discharging oxygen which has been separated from the oxygen-containing gaseous mixture by permeation through the dense mixed conducting oxide layer of each membrane unit and passage into the manifolds or conduits via the channel-free porous support of each membrane unit.Type: GrantFiled: March 13, 1995Date of Patent: October 28, 1997Assignee: Air Products and Chemicals, Inc.Inventors: Dale M.
