Patent number: 4789451Abstract: Apparatus for reducing oxalic acid to a product includes a cell. A separator which separates the cell into two chambers; a catholyte chamber and an anolyte chamber. Each chamber has an inlet and an outlet. A porous cathode having a catalyst is arranged within the catholyte chamber so that a catholyte entering the inlet of the catholyte chamber will pass through the cathode. A porous anode is arranged within the anolyte section so that an electrolyte entering the inlet of the anolyte section will pass through the anode and exit through the outlet of anolyte section. A source provides the catholyte which is a mixture of oxalic acid and an electrolyte to the inlet of the catholyte chamber while another source provides the electrolyte to the inlet of the anolyte chamber. A d.c. voltage is provided between the cathode and the anode so as to cooperate in the reduction of oxalic acid within the porous cathode to a product which exits the catholyte chamber by way of its outlet.Type: GrantFiled: September 3, 1985Date of Patent: December 6, 1988Assignee: Texaco Inc.Inventors: Abraham Morduchowitz, Anthony F.

Patent number: 4732655Abstract: A method and apparatus for providing two chemical products includes a reaction cell having an anode chamber and a cathode chamber. The anode chamber is separated from the cathode chamber by an ionic transfer membrane. Each chamber has an electrode connected to a source of DC voltage. A first electrolyte with a first sparging gas is provided to the anode chamber, while a second electrolyte with a second sparging gas is provided to the cathode chamber. The DC voltage, in cooperation with the electrolytes and the sparging gases causes products to form, one in each chamber. The first product is removed from the reacted electrolyte that emerges from the anode chamber while the second product is removed from the reacted electrolyte emerging from the cathode chamber.Type: GrantFiled: June 11, 1986Date of Patent: March 22, 1988Assignee: Texaco Inc.Inventors: Abraham Morduchowitz, Ronald L.

Patent number: 4595465Abstract: A process and apparatus for converting metallic elements to metallic oxalates in the presence of carbon dioxide includes two redox couple electrolyte solutions separated by a first membrane having photosensitizers. The carbon dioxide to be reduced is provided to a second membrane which is contiguous to one of the redox couple electrolyte solutions. The second membrane has photosensitizers and a catalyst. A non-aqueous electrolyte slurry, which includes a metal element, solvent and salt, is provided in a manner so that some of the slurry is in contact with the second membrane. Both membranes are illuminated and electrical voltage is provided across the electrolyte solutions and the electrolyte slurry in a manner so that there is one electrode in another electrolyte solution and another electrode in the electrolyte slurry so as to cause a reaction between the carbon dioxide at the second membrane and the electrolyte slurry to produce the metallic oxalate.Type: GrantFiled: December 24, 1984Date of Patent: June 17, 1986Assignee: Texaco Inc.Inventors: Peter G. P. Ang, Anthony F. Sammells, Abraham Morduchowitz

Patent number: 4563254Abstract: Apparatus for the carbonylation of nitrobenzene or 2-5 dinitrotoluene with carbon dioxide to provide a product includes a housing which contains an electrolyte solution having a non-aqueous electrolyte containing a supporting electrolyte. A membrane divides the housing into two sections while permitting ions to move between the two sections. Carbon dioxide and nitrobenzene or 2-5 dinitrotoluene are provided to the housing. A d.c. voltage is provided across the electrolyte solution in the two sections of the housing, to cooperate in a reaction of the carbon dioxide, the nitrobenzene or the 2-5 dinitrotoluene and the electrolyte solution to provide a chemical product.Type: GrantFiled: February 7, 1985Date of Patent: January 7, 1986Assignee: Texaco Inc.Inventors: Abraham Morduchowitz, Anthony F.
