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 ...
