Partial oxidation of sewage sludge

摘要: Municipal sanitary sewage sludge is disposed of by an improved partial oxidation process without polluting the environment. Aqueous slurries are upgraded hydrothermal treatment, preferably while being sheared, concentrated, and then mixed with a supplemental fuel, coal. A pumpable aqueous slurry sludge-coal and/or petroleum coke thereby produced having greater total solids heat content (HHV) as well containing increased amount for reacting free-oxygen gas in free-flow generator. Hot quench water or steam cooling hot raw effluent stream synthesis gas, reducing fuel from gasifier may provide step.
