PROCESS FOR THE PURIFICATION OF GASES

摘要

A process is known for the electrolytic removal of a contaminant from gases, wherein the gas and a liquid electrolyte are passed co- or counter-currently through a fixed bed electrode of an electrolysis cell which has a counterelectrode separated from the fixed bed electrode by a separator and the contaminant is electrochemically converted at an effective cell voltage. Such cells have hitherto been operated in a flooded state. According to the invention, the degree of purification may be substantially increased if the fixed bed electrode is operated as a trickle bed reactor.
