Abstract: A process is disclosed for gasifying solid coal particles in a rotary kiln that produces simultaneously and continuously two distinctly different fuel gas streams from the opposite ends of a single kiln. A relatively low temperature gas is discharged from the solids inlet end of the kiln, which contains substantially all tars produced by the process. A second of the gas streams is discharged from the solids discharge end of the kiln at approximately 1,900.degree. F. and substantially tar-free. Heat is recovered from this tar-free gas after only a simple cleaning of particulate matter, as may be provided by a cyclone separator.
