NOVELTY - Preparation of a coupled radical product from biomass (104) comprises: obtaining a quantity of biomass; converting the biomass into at least one alkali metal salt of a carboxylic acid; preparing an anolyte, where the anolyte comprises a quantity of the alkali metal salt of the carboxylic acid; and decarboxylating the alkali metal salt of the carboxylic acid within the anolyte, where the decarboxylating converts the alkali metal salt of the carboxylic acid into alkyl radicals that react to form a coupled radical product.    USE - The process is useful for preparing a coupled radical product comprising a hydrocarbon, from biomass, where the biomass comprises carbohydrates, carboxylic acids, esters of carboxylic acids, triglycerides, lipids, oils, phospholipids, carboxylic acid derivatives, lignins, tall oil, resins, switch grass, algae, and/or metal salts of carboxylic acids; or an animal, a plant, and/or a microbial (all claimed).    ADVANTAGE - The process is: inexpensive; and capable of producing a variety of different hydrocarbons.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for producing a coupled radical product from biomass comprising: providing an electrolytic cell comprising an anolyte compartment housing an anolyte, a catholyte compartment housing a catholyte, and a NaSICON membrane separating the anolyte compartment and the catholyte compartment; obtaining a quantity of a biomass comprising a lipid; converting the lipid into a fatty acid by one or more of hydrolysis, fermentation, and saponification; saponifying the fatty acid to produce a sodium metal salt of fatty acid; where the anolyte comprises a quantity of the sodium metal salt of the fatty acid and at least one G-type solvent and at least one H-type solvent; and decarboxylating the sodium metal salt of the fatty acid within the anolyte, where the decarboxylating converts the sodium metal salt of the fatty acid into alkyl radicals that react to form a coupled radical product comprising a hydrocarbon.
