Waste treatment process

A process of gasifying waste containing organic substances which may be combusted or gasified by means of partial oxidation in the presence of air or oxygen and steam. The gasification process includes the step of adjusting the molar ratio of steam/carbon (H2O/C) for supplied steam and the organic s...

More Information
Summary:A process of gasifying waste containing organic substances which may be combusted or gasified by means of partial oxidation in the presence of air or oxygen and steam. The gasification process includes the step of adjusting the molar ratio of steam/carbon (H2O/C) for supplied steam and the organic substances containing carbon to a desired ratio. The process continues with partial oxidation at about 700 DEG C to about 900 DEG C and discontinuing the steam supply while continuing only air or oxygen supply to combust the remaining combustibles having carbon as their major component.
