ABSTRACT:
A novel electrolytic cell and process are described for producing alkaline peroxide solutions. The cell has an anode and cathode in spaced apart relationship, with the cathode being in the form of a fluid permeable conductive mass e.g. a packed bed of graphite particles, separated from the anode by a barrier wall. This barrier wall can be either a cation specific membrane dividing the cell into separate cathode and anode chambers or an insulating mesh permitting free flow of electrolyte between the cathode and anode. An aqueous alkaline electrolyte and oxygen are passed through the cathode bed and the peroxide is generated in the solution within the cathode bed. The alkaline peroxide obtained is directly usable in wood pulp bleaching operations.
