METHOD AND APPARATUS FOR LIQUEFACTION AND DISTILLATION OF VOLATILE SUBSTANCES CONTAINED IN SOLID CARBONACEOUS MATERIAL Russian patent published in 2015 - IPC C10B47/28 

FIELD: chemistry.

SUBSTANCE: method includes passing material through a reformer having a temperature gradient therein, which rises as the material flows down through the reformer. More valuable volatile components of the material exit the material at their respective vaporisation temperatures, and come out of the reformer for processing in condensers. A portion 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 occurs at a level below that where the fraction exited the reformer so that the recycled fraction will again come 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.

EFFECT: invention improves efficiency of processing coal and enables to separate volatile substances into a valuable gas and liquid fractions.
