ABSTRACT:
A process for gasifying coal to produce carbon monoxide and hydrogen in which a first stream of coal is burned without bed formation in a combustion zone in the presence of water under oxidation conditions to produce gases comprising carbon dioxide and steam. A second stream of coal is maintained as a fluid bed in a separate gasifier zone by upflowing carbon dioxide and steam from the combustion zone while being gasified under reducing conditions to produce carbon monoxide and hydrogen. A foul water stream from an external process containing pollutants and/or dissolved salts is charged to the combustion zone resulting in combustion of pollutants and slagging of dissolved salts contained therein.
