A new Kraft white liquor oxidation process has been demonstrated. The process using a novel catalyst can effectivily produce a polysulfide cooking liquor. The selected catalyst is a granulated activated carbon, characterized by a large pore volume occupied with pores more than 10 nm diameter. This catalyst has high oxidation activity and selectivity of polysulfied formation. The polysulfide yield in higher than the reported value. One year pilot plant test exibited steady performance using milldoi:10.2524/jtappij.42.46 fatcat:ycg5b3i64fh4fg52jrutznfhzq
