AMALGAMZERSETZUNGSVORRICHTUNG FÜR QUECKSILBERKATHODENZELLEN FÜR DIE ALKALICHLORIDELEKTROLYSE

摘要

The invention relates to an amalgam decomposer for mercury cathode chlor-alkali cells. The amalgam decomposer of the invention contains a filling of carbon steel rings whose external surface is provided with a catalytic coating for amalgam decomposition consisting of one or more electrically conductive metals carbides. The internal surface of the rings is free of catalytic coating and wettable by the amalgam, while the external carbide catalytic coating is not wettable by the amalgam thereby favoring hydrogen evolution.
