ABSTRACT:
An improvement in the fixed-bed pressure gasification of coal is described. The improvement includes removing at least a portion of the hydrocarbon (e.g., tar) from the raw gaseous fuel produced in the gasification process and apparatus for introducing the removed hydrocarbon directly into the interior of the coal bed below the devolatilization zone and at or above the maximum-temperature location in the bed.
