Our membranes are hermetic thereby preventing mixing of anolyte and catholyte solutions. They are also ion-selective allowing only Na+ or Li+ to go though. They have the requisite chemical compatibility with large set of chemicals. These features allows production of energetic and high-purity chemicals from low-cost, impure and industrial waste feedstocks. Finally, the membranes can be made in large area plate and tube formats and can be used as a replacement for polymer membranes in electrosynthesis applications.

The membranes can be applied for anodic decarboxylation of sodium carboxylates to produce radicals or carbocations that can then be converted into valuable low-oxygen organics.

Several chemicals including low/high carbon number linear/branched alkanes, alkenes, dienes, alcohols and diols can be produced by decarboxylation of carboxylate feedstocks using our membrane technology. This technology uses low-cost impure carboxylic acid feedstocks from biomass and convert them to industrial commodity chemicals such as surfactants, lubricants, monomers, high-energy fuels such as JP-8 and gasoline.

Electrochemical synthesis of aryl-alkyl surfactant precursor.

The present solid-electrolyte membranes can be used to make high purity, low-moisture containing sodium and lithium alcoholates in a simple two-compartment electrolysis cell.

We have made pilot-scale demonstration of producing sodium methylate (methoxide) that is the catalyst in the transesterification of triglycerides to biodiesel. The patented process converts aqueous sodium hydroxide to sodium methylate in methanol in an electrolysis reactor containing sodium conducting membrane. Other reagent grade lithium and sodium alcoholates can be similarly produced.

Electrolytic method to make alkali alcoholates using ceramic ion conducting solid membranes.

Another group of applications for our membranes is in recovering or producing valuable inorganic sodium and lithium chemicals from low-cost & impure aqueous feedstocks.

The membrane technology can be applied for two- & three- compartment electrochemical salt splitting by which an impure sodium and lithium salts can be converted to purer and higher value salts, bases and acids. Examples of the processes include production of sodium hypochlorite (bleach) from sodium chloride brine, baking soda from caustic, and lactic acid from sodium lactate. Lithium and sodium in concentrated form can be recovered from industrial streams containing low-concentrations of these alkali metal ions.
