Shankar Nataraj, Steven Lee Russek, Paul Nigel Dyer: Synthesis gas production by mixed conducting membranes with integrated conversion into liquid products. Air Products and Chemicals, John M Fernbacher, September 5, 2000: US06114400 (102 worldwide citation)

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 o ...

Shankar Nataraj, Steven Lee Russek: Utilization of synthesis gas produced by mixed conducting membranes. Air Products and Chemicals, John M Fernbacher, August 29, 2000: US06110979 (78 worldwide citation)

Hydrocarbon feedstocks are converted into synthesis gas in a two-stage process comprising an initial steam reforming step followed by final conversion to synthesis gas in a mixed conducting membrane reactor. The steam reforming step converts a portion of the methane into synthesis gas and converts e ...

Doohee Kang, Steven Lee Russek, Robert Michael Thorogood, Rodney John Allam, Anthony Knut James Topham: High temperature oxygen production with steam and power generation. Air Prod & Chem, October 30, 1996: EP0739649-A1

Oxygen is separated from air by means of a high temperature ion transport membrane which is integrated with a gas turbine system for energy recovery from the membrane nonpermeate stream. Air is compressed, heated in a first heating step, and passed through the feed side of a mixed conductor membrane ...
