Partial oxidation of sewage sludge

Patent ·
OSTI ID:6661599
; ; ;

This patent describes a process for the partial oxidation of sewage sludge. It comprises: shearing without heating a concentrated aqueous slurry of sewage sludge obtained from sewage.; dewatering the sheared pumpable aqueous slurry of sewage sludge from (1) to a solids content in the rage of about 25 to 50 wt. %; mixing the pumpable sheared aqueous slurry of sewage sludge with a supplemental solid fuel and reacting the pumpable aqueous sewage sludge-coal and/or petroleum coke slurry in the reaction zone of a partial oxidation gas generator at a temperature in the range of about 1800{degrees} F. to 2800{degrees} F.
