An electrolysis process and electrolytic cell.

摘要

Disclosed is an electrolysis process which is characterized by carrying out the electrolysis of an aqueous alkali metal halide solution while supplying a cathode liquor into a cathode compartment (2) formed between a cation exchange membrane (3) positioned substantially horizontal and a cathode plate (16) of gas-liquid impermeability, with which the membrane (3) is wetted, than a mixed stream of the cathode liquor and cathode gas being removed from the cathode compartment (2). Also disclosed is an electrolytic cell which is comprised of an upper anode compartment (1) and a lower cathode compartment (2) partitioned by a cation exchange membrane (3) positioned substantially horizontal, said anode compartment (1) having therein substantially horizontal anodes (12) and an anolyte solution inlet (13) and outlet (14), and said cathode compartment (2) having a cathode plate (16) with gas-liquid impermeability and a cathode liquor inlet (19) and an outlet (20) of a mixed stream of the cathode liquor and cathode gas.
