  • Method of reutilizing kraft spent liquor
    Patent number: 4334956
    Abstract: A method of utilizing kraft black liquor by converting the black liquor to "green liquor" and then oxidizing the green liquor with air in the presence of a quinone compound or spent liquor from the kraft process, the soda semi-chemical process or the neutral sulfite semi-chemical process as a catalyst. A marked improvement in the rate of oxidation is obtained. The thus oxidized green liquor is then able to be used as part at least of the digestion liquor in the NSSC process.
