A method for liquefaction of coal or other solid carbonaceous material includes passing the material through a reformer having a temperature gradient therein, the temperature gradient generally increasing as the material flows down through the reformer. The more valuable volatile components of the material exit the material at their respective vaporization temperatures, and pass out of the reformer for processing in condensers. Some of each fraction of the volatile material flow is re-heated and recycled through the reformer to supply heat to maintain the temperature gradient, the recycling injection occurring at a level below that where the fraction exited the reformer so that the recycled fraction will again pass out of the reformer to be condensed. At the bottom of the reformer, the non-volatile portion of the carbonaceous material is removed from the reformer for further processing or sale.
