Abstract: An electrochemical reactor comprising an electrolyte compartment wherein at least one of the side walls of the electrolyte compartment is an electrode and an opposite side wall comprises a separator element. Further there is a plurality of electrically conductive granules forming a working electrode for a electrochemical main reaction in the electrolyte compartment and enclosed in the electrolyte compartment. The granules comprise a first material exhibiting at least a first activation overpotential for an electrochemical side reaction within a distance d from the separator element. The electrochemical reactor comprises a spacer element for maintaining the granules at least at a distance d from the separator element on the electrolyte-facing side of the separator element.
Abstract: The disclosure pertains to an electrochemical reactor (1, 13), in particular but not exclusively for vatting sulphur dye or vat dye as well as to methods of using such a reactor and to uses of such a reactor.
