Patent number: 6218556Abstract: An electrochemical process for hydrogenating an unsaturated fatty acid, mixtures of two or more fatty acids, or the unsaturated fatty acid constituents of an edible or non-edible oil's triglycerides is performed using a solid polymer electrolyte reactor. Membrane electrode assemblies consist of a cation exchange membrane onto which porous anode and cathode electrodes are attached. As the electrodes are permeable, reactant and products enter and leave the membrane/cathode and membrane/anode reaction zones via the back sides of the electrodes. Hydrogen is generated in situ by the electro-reduction of protons that are formed at the anode and which migrate through the ion exchange membrane for reaction with the fifty acids or fatty acid constituents. In the disclosed process, only protons (H+ ions) carry the current between the anode and the cathode. The need for a supporting electrolyte to conduct electricity has been circumvented.Type: GrantFiled: November 12, 1996Date of Patent: April 17, 2001Assignee: The Administrators of the Tulane Educational FundInventor: Peter N. Pintauro

Patent number: 5559259Abstract: The invention relates to a poison-resistant catalytically active microporous membrane to be used for heterogeneously catalyzed reactions, which membrane is characterized in that it is permeable to one of the reactants separated by said membrane, and that it is impermeable to the other reactants and the contaminants contained therein, the molecules of all of which are larger in size than the pore size of the membrane, and to a process for carrying out a heterogeneously catalyzed reaction under conditions preventing the catalyst from being poisoned. This membrane allows to conduct three-phase reactions in a new manner, whereby the reaction gas is directly transported to the active sites.Type: GrantFiled: November 3, 1995Date of Patent: September 24, 1996Assignee: Studiengesellschaft Kohle mbHInventor: Wilhelm F.
