Microbial electrosynthesis is a carbon capture technology capable of transforming CO2 into valuable organic compounds. The aim of this article is to model the simultaneous production and separation of acetate in an anion-exchange membrane microbial electrosynthesis cell which employs CO2 as feedstock.
The maximum amount of acetate product produced was 0.72 mmol after 19 operational days. Simultaneous production and separation of acetate begun after 4 days when 0.95 mol/m3 and 0.04 mol/m3 of acetate were detected in the cathode and anode MES cell chambers respectively. A model which fits the simultaneous production and separation of acetate in the microbial electrosynthesis cell was successfully developed and validated.
The microbial electrosynthesis model developed in this work can be used to predict the product concentrations of a carbon capture technology which simultaneously produces and separates acetate product.
