Separation of volatile products from solid carbonaceous material

Patent ·
OSTI ID:7204675
A process is described for separating condensable volatile products from solid carbonaceous material distilled in a retort, which consists in heating the material to a graduated temperature, leading the distilled vapors that arise from the material at any one of the number of regions differing in temperature into contact with relatively cooler portions of the material in its solid or partly vaporized state in the retort, and removing the liquefied volatile matter condensed by the cooler portions of the material without permitting it to return to hotter regions of the retort.
