<P><B>Abstract</B></P><P><B>BACKGROUND</B></P><P>Microbial electrosynthesis is a carbon capture technology capable of transforming CO<SUB>2</SUB> into valuable organic compounds. The aim of this article is to model the simultaneous production and separation of acetate in an anion&#8208;exchange membrane microbial electrosynthesis cell which employs CO<SUB>2</SUB> as feedstock.</P><P><B>RESULTS</B></P><P>The maximum amount of acetate product produced was 0.72 mmol after 19 operational days. Simultaneous production and separation of acetate began after 4 days when 0.95 mol m<SUP>&minus;3</SUP> and 0.04 mol m<SUP>&minus;3</SUP> of acetate were detected in the cathode and anode MES cell chambers, respectively. A model that fits the simultaneous production and separation of acetate in the microbial electrosynthesis cell was successfully developed and validated.</P><P><B>CONCLUSION</B></P><P>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. &copy; 2016 Society of Chemical Industry</P>
