Fischer–Tropsch acid water processing by Kolbe electrolysis

Fischer–Tropsch acid water processing by Kolbe electrolysis
Fischer–Tropsch synthesis produces roughly equal amounts of water and oil as products. The water product is acidic due to dissolved carboxylic acids. Treating this acid water in small-scale facilities designed for remote locations is a challenge, because conventional biological treatment might be impractical. Kolbe electrolysis was investigated as potential process for acid water treatment in such small-scale facilities. The Kolbe electrolysis of acetic acid in dilute aqueous solution produced methane, ethane and CO2 as expected. However, current efficiencies in the operating range 10–30°C were less than 3% and the energy required for acetic acid conversion was >2GJ/kg acid. Hydrogen was co-produced by water electrolysis and the overall current efficiency of acetic acid and water electrolysis was of the order 20%. Despite being technically viable, it appeared unpromising compared to alternative electrolysis processes for use in small-scale remote Fischer–Tropsch facilities.
