ABSTRACT:
A process for treating solid organic materials, especially for recycling treated wood, uses energy provided by hot gases at the bottom of a reactor column to perform a distillation operation which ensures splitting of organic bonds in the material and uses, as the distillation operation progresses, constant control between a first temperature of the hot gases before they are introduced into the lower part of the reactor column and a second temperature of a layer of the material located in an area immediately above the grid of the reactor column. When the first temperature and the second temperature are identical or virtually identical, corresponding to removal of all the organic bonds of the material by evaporation and transport by the hot gases from the bottom to the top of the column, the layer of material at the second temperature is removed in order to collect a material that largely consists of carbon and constitutes a secondary raw material.
