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 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 monoxide and steam from the combustion zone while being gasified under reducing conditions to produce carbon monoxide and hydrogen. A high sulfur carbonaceous material from an external process comprises at least in part said first stream of coal entering the combustion zone and the sulfur dioxide produced therefrom in the combustion zone is reduced entirely to hydrogen sulfide in passage through the fluid bed gasifier zone.
