Electrochemical methods and systems using catalytic materials

Title: Electrochemical methods and systems using catalytic materials

Abstract

The oxygen evolution reaction (OER)-catalyzing activity of transition metal perovskite oxide catalysts depends on the occupancy of the σ-bonding orbital of eg symmetry parentage of the active cation. Catalysts having preferred values of eg orbital filling can have a high intrinsic activity for catalysis of the OER.

Enhancing electrochemical methods for producing and regenerating alane by using electrochemical catalytic additive

Patent Zidan, Ragaiy

A process of using an electrochemical cell to generate aluminum hydride (AlH.sub.3) and other high capacity hydrides is provided. The electrolytic cell uses an electro-catalytic-additive within a polar non-salt containing solvent to solubilize an ionic hydride such as NaAlH.sub.4 or LiAlH.sub.4. The resulting electrochemical process results in the formation of AlH.sub.3 adduct. AlH.sub.3 is obtained from the adduct by heating under vacuum. The AlH.sub.3 can be recovered and used as a source of hydrogen for the automotive industry. The resulting spent aluminum can be regenerated into NaAlH.sub.4 or LiAlH.sub.4 as part of a closed loop process of AlH.sub.3 generation.

Catalysts having catalytic material applied directly to thermally-grown alumina and catalytic methods using same, improved methods of oxidative dehydrogenation

Patent Ida, Junko; Daly, Francis P.; Mazanec, Terry; ...

The invention describes catalysts, methods of making catalysts, methods of making a microchannel reactor, and methods of conducting chemical reactions. It has been discovered that superior performance can be obtained from a catalyst formed by directly depositing a catalytic material onto a (low surface area) thermally-grown alumina layer. Improved methods of conducting oxidative dehydrogenations are also described.

Anode-cathode power distribution systems and methods of using the same for electrochemical reduction

Patent Koehl, Eugene R; Barnes, Laurel A; Wiedmeyer, Stanley G; ...

Power distribution systems are useable in electrolytic reduction systems and include several cathode and anode assembly electrical contacts that permit flexible modular assembly numbers and placement in standardized connection configurations. Electrical contacts may be arranged at any position where assembly contact is desired. Electrical power may be provided via power cables attached to seating assemblies of the electrical contacts. Cathode and anode assembly electrical contacts may provide electrical power at any desired levels. Pairs of anode and cathode assembly electrical contacts may provide equal and opposite electrical power; different cathode assembly electrical contacts may provide different levels of electrical powermore »« less
