ABSTRACT:
The overall conversion of coal to synthesis gas by pressurized counter-current gasification is improved by steam reforming the methane values in the gas and heating the steam reformer by means of a fluidized bed combustor fuelled by the coal fines which are too small to be employed in the gasification step. Coal can be crushed to increase the proportion of fines and/or conditions for gasifications and/or steam reforming varied so as to consume lump coal and fines in the desired ratio. The product gas may be used for methanol synthesis.
