Abstract

DC60 (17/10/47) Process for electrolysis of alkali metal halide salts in Electrolyte cells, which have anode chambers with anode At least one The cathode chamber contains at least one cathode and the membrane in contact with this cathode (hence forms the pulp-electrode assembly) separating the anode chamber from the cathode chamber.This method consists of (a) feeding. L-type saline Caly metal halide enters the anode chamber (b) electrolysis. Of alkali metal saline This halide to produce halogen gas. And alkali metal ions (c) conduction of alkali metal ions and water through the membrane into the cathode chamber, and (d) feeding oxygen-containing gas to the cathode chamber, so oxygen is reduced. The cathode and produces a concentrated alkali methyl hydroxide solution. The process is further characterized by having a field Flow near the cathode to Facilitates the movement of oxygen gas to the cathode and transport of alkali metal. Hydroxides are removed from this cathode and in a special way that the flow field is composed of a conductive material. At least 30% pore condition and at least average pore size of 10 microns. Process for electrolysis of alkali metal halide saline in an electrolyte shell with room. Anode with anode At least one Cathode chamber with at least the cathode This method consists of: (a) L-type saline infusion (thus forming a membrane-electrode assembly) separating the anode chamber from the cathode chamber. Cali metal halide to the anode chamber (b) electrolysis Of alkali metal halide brine to produce halogen gas And alkali metal ions (c), conductivity of alkali metal ions and Water moves through the membranes into the cathode chamber and (d) the oxygen-containing gas is fed to the cathode chamber, so oxygen is reducted at this cathode and produces an alkali methyl hydroxide solution. This process is further characterized by the presence of a field The flow consists of a conductive material with at least 30% porosity and at least an average pore size of 10 chiron.
