ABSTRACT:
Process and apparatus for recovering volatile distillates from coal, and other solid carbonaceous fuel sources, by heating the top surface of a bilayer of coal formed of an upper layer of recycled coal and a lower layer of green coal, maintaining the lower level of green coal at a temperature cool enough to condense constituents distilled from the upper layer of recycle coal, and recycling the once passed green coal as recycle coal is disclosed.
