ABSTRACT:
Coal is gasified to produce a coal gasification effluent and a char residue. The char residue is cooled by indirect heat transfer in a char bed, and the coal gasification effluent is passed through the cool char bed to effect cooling of the coal gasification effluent, with tars and oil present in the effluent being absorbed by the char bed. In this manner, the gasification effluent is cooled without fouling of heat transfer surfaces, and tars and oils are effectively removed therefrom.
