Patent number: 9023901Abstract: A synthesis gas conversion process and system are disclosed. Fresh syngas from a methane reformer is used as a sweep zone gas feed which is caused to flow across a water permselective membrane in a membrane reactor. The water permselective membrane is adjacent a synthesis gas conversion reaction zone in which synthesis gas is contacted with a catalyst and converted to effluent including water. Water is removed from the reaction zone through the membrane and passes out of the reactor with the sweep zone gas. The water is then removed from the sweep zone gas forming a modified gas feed which is fed to the reaction zone. The modified gas feed has a preferred H2/CO ratio to feed into the reaction zone.Type: GrantFiled: July 31, 2013Date of Patent: May 5, 2015Assignee: Chevron U.S.A. Inc.Inventors: Lixin You, Shabbir Husain, Christopher M. Chen

Patent number: 8114193Abstract: An ion transport membrane system comprising (a) a pressure vessel having an interior, an exterior, an inlet, and an outlet; (b) a plurality of planar ion transport membrane modules disposed in the interior of the pressure vessel and arranged in series, each membrane module comprising mixed metal oxide ceramic material and having an interior region and an exterior region, wherein any inlet and any outlet of the pressure vessel are in flow communication with exterior regions of the membrane modules; and (c) one or more gas manifolds in flow communication with interior regions of the membrane modules and with the exterior of the pressure vessel. The ion transport membrane system may be utilized in a gas separation device to recover oxygen from an oxygen-containing gas or as an oxidation reactor to oxidize compounds in a feed gas stream by oxygen permeated through the mixed metal oxide ceramic material of the membrane modules.Type: GrantFiled: January 18, 2008Date of Patent: February 14, 2012Assignee: Air Products and Chemicals, Inc.Inventors: VanEric Edward Stein, Michael Francis Carolan, Christopher M. Chen, Phillip Andrew Armstrong, Harold W. Wahle, Theodore R. Ohrn, Kurt E. Kneidel, Keith Gerard Rackers, James Erik Blake, Shankar Nataraj, Rene Hendrik Elias Van Doorn, Merrill Anderson Wilson
