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.
Abstract: For implementing startup and priming phases of a vegetable carbon production method, an installation includes a generator of hot gases with low oxygen content, and a fan downstream which boosts the hot gases into a lower part of a reactor. The reactor includes a column of substantial height whose upper inlet, with a temperature T3 of less than 65° C., is used to continuously load and add biomass and whose lower part has a grid for support and removal of the load, an underlying injection chamber for the gases from the generator, and a mechanism for retrieving processed substances. The installation also includes, at the outlet for cold gases at temperature T3 at the top of the reactor column, a thermal post-combustion chamber for the extracted gases, a heat exchanger, a fan, a second heat exchanger, a vent and connecting pipes.
