    Abstract: A method that produces coupled radical products from biomass. The method involves obtaining a lipid or carboxylic acid material from the biomass. This material may be a carboxylic acid, an ester of a carboxylic acid, a triglyceride of a carboxylic acid, or a metal salt of a carboxylic acid, or any other fatty acid derivative. This lipid material or carboxylic acid material is converted into an alkali metal salt. The alkali metal salt is then used in an anolyte as part of an electrolytic cell. The electrolytic cell may include an alkali ion conducting membrane (such as a NaSICON membrane). When the cell is operated, the alkali metal salt of the carboxylic acid decarboxylates and forms radicals. Such radicals are then bonded to other radicals, thereby producing a coupled radical product such as a hydrocarbon. The produced hydrocarbon may be, for example, saturated, unsaturated, branched, or unbranched, depending upon the starting material.

    Abstract: A method for alkylating aromatic compounds is described using an electrochemical decarboxylation process. This process produces aryl-alkyl compounds that have properties useful in Group V lubricants (and other products) from abundant and economical carboxylic acids. The process presented here is also advantageous as it is conducted at moderate temperatures and conditions, without the need of a catalyst. The electrochemical decarboxylation has only H2 and CO2 as its by-products, as opposed to halide by-products.

    Abstract: Electrochemical systems and methods for producing hydrogen. Generally, the systems and methods involve providing an electrochemical cell that includes an anolyte compartment holding an anode in contact with an anolyte, wherein the anolyte includes an oxidizable substance having a higher standard oxidation potential than water. The cell further comprises a catholyte compartment holding a cathode in contact with a catholyte that includes a substance that reduces to form hydrogen. Additionally, the cell includes an alkali cation conductive membrane that separates the anolyte compartment from the catholyte compartment. As an electrical potential passes between the anode and cathode, the reducible substance reduces to form hydrogen and the oxidizable substance oxidizes to form an oxidized product. The pH within the catholyte compartment may be controlled and maintained to a value in the range of 6 to 8. Apparatus and methods to regenerate the oxidizable substance are disclosed.

    Abstract: A method for removing nitrogen from natural gas includes contacting substantially dry natural gas that contains unwanted nitrogen with lithium metal. The nitrogen reacts with lithium to form lithium nitride, which is recovered for further processing, and pipeline quality natural gas. The natural gas may optionally contain other chemical species that may be reduced by lithium, such as carbon dioxide, hydrogen sulfide, and small amounts of water. These lithium reducible species may be removed from the natural gas concurrently with the removal of nitrogen. The lithium nitride is subjected to an electrochemical process to regenerate lithium metal. In an alternative embodiment, lithium nitride is reacted with sulfur to form lithium sulfide and nitrogen. The lithium sulfide is subjected to an electrochemical process to regenerate lithium metal and sulfur. The electrochemical processes are advantageously performed in an electrolytic cell containing a lithium ion selective membrane separator.

    Abstract: Hydrocarbons may be formed from six carbon sugars. This process involves obtaining a quantity of a hexose sugar. The hexose sugar may be derived from biomass. The hexose sugar is reacted to form an alkali metal levulinate, an alkali metal valerate, an alkali metal 5-hydroxy pentanoate, or an alkali metal 5-alkoxy pentanoate. An anolyte is then prepared for use in a electrolytic cell. The anolyte contains the alkali metal levulinate, the alkali metal valerate, the alkali metal 5-hydroxy pentanoate, or the alkali metal 5-alkoxy pentanoate. The anolyte is then decarboxylated. This decarboxylating operates to decarboxylate the alkali metal levulinate, the alkali metal valerate, the alkali metal 5-hydroxy pentanoate, or the alkali metal 5-alkoxy pentanoate to form radicals, wherein the radicals react to form a hydrocarbon fuel compound.
