  • Electrolytic process of an aqueous alkali metal halide solution and electrolytic cell used therefor
    Patent number: 4586994
    Abstract: Disclosed is an electrolytic process using a horizontal type cation exchange membrane electrolytic cell in which catholyte liquor is supplied into a cathode compartment with initial linear velocity of at least 8 cm/sec and gas content of at most 0.6 at a catholyte liquor outlet. Also disclosed is an electrolytic cell used for the foregoing process. The invention enables not only conversion of a mercury electrolytic cell to a cation exchange membrane electrolytic cell with low cost, but the long-term and stable operation.

  • Vertical type electrolytic cell and electrolytic process using the same
    Patent number: 4574037
    Abstract: Disclosed is a vertical type electrolytic cell partitioned by an ion exchange membrane into an anode compartment and a cathode compartment, the cathode compartment being divided by a non-perforated cathode plate into a cathode gas generation room and a cathode gas separation room. Also disclosed is an electrolytic process using the electrolytic cell wherein the catholyte is circulated between the two rooms as a result of a gas lift effect produced by the cathode gas.
