Abstract

There is disclosed a process for synthesis of a C2-8 alkane comprising: (a) providing an electrolyte formulation comprising from about 3N to about 6N C2-C5 carboxylic acid and from about 2 M to about 4 M alkali C2-C5 carboxylate, wherein the C2-C5 carboxylate and carboxylic acid have the same carbon alkyl length into a pressure vessel having an electrode cell or stack; (b) adding electrical current to the electrode cell or stack; (c) pressurizing the pressure vessel; and (d) recovering a gas stream from the pressure vessel comprising a C2-8 alkane, CO2 and H2. Preferably, the carboxylic acid is acetic acid and the alkane is ethane.
