Abstract

Synthesis gas is produced by partial oxidation of slurried coal followed by separation of ash, the temperature of the gas being thereafter controlled to permit a desired portion thereof to be directly contacted with water to achieve a gas/stream mixture of predetermined composition prior to shift conversion, the other portion being preferably convectively cooled for maximum thermal efficiency and then scrubbed prior to withdrawal as carbon monoxide-containing product.
