Electrochemical technology to purify electrocatalytic co2 and co reduction product streams from supporting electrolytes and other ionic species

Abstract

A method for the purification of a reaction crude can include employing one or more electrodeionization modules each including a cathode, an anode, and at least one ion-depletion compartment interposed between pairs of ion-concentration compartments. Each ion-concentration compartment can contain an ion-exchange medium. The method can include passing a reaction crude through each ion depletion compartment. The reaction crude can be produced from a process including at least one ionic species. The method can include supplying current between the anode and the cathode. The method can include recovering an ion-depleted stream from each ion-depletion compartment. The method can include recovering the ionic or ionizable species from each ion-concentration compartment.
