ABSTRACT:
An elongated tube (preferably stainless steel) is maintained at a temperature of at least about 1000.degree. F. throughout its length. Coal or other carbonaceous feed material is moved through the tube at a uniform rate of speed in the substantial absence of air, with the feed material being constantly churned or turned as by a screw conveyor. The churning of the feed material and the diameter of the tube is such that the material is subjected to "shock" heating, whereby gases and vapors are violently released from the solid mass and are removed therefrom at a vacuum of from about two to about five inches of mercury, with said gases and vapors passing through the aforesaid churning mass. The residue is recovered and the gases and vapors are subsequently passed through conventional condensers and scrubbers to liquify the oil and separate the gases and the water.
