Method for treating carbonaceous materials by vapor thermolysis

A method for treating carbonaceous materials by steam thermolysis, comprising:

• shredding carbonaceous waste materials,
• introducing the shredded carbonaceous waste materials into a steam thermolysis reactor heated by combustion gases, including gases laden with steam being introduced into the steam thermolysis reactor, so as to heat said shredded carbonaceous waste materials to a temperature between 200 and 700° C. during a steam thermolysis reaction to form vapor-gas products,
• cooling the combustion gases to a temperature between 200 and 450° C. and discharging said gases,
• discharging from the reactor the vapor-gas products formed in the reactor by steam thermolysis, followed by condensation of said vapor-gas products to provide a condensate,
• separating the condensate obtained by said condensation into water containing residual hydrocarbons and into oil;
• wherein, the water separated from the condensate is directed injected into a burner by spray nozzles and combusted in the burner, wherein the water is treated at a temperature and dwell time sufficient to provide complete oxidation of organic compounds and elimination of odors, and wherein the water combusted in the burner generates steam as a source of heat energy for the steam thermolysis reactor, and wherein the source of heat energy further comprises (i) said combustion gases coming from combustion of a fuel, (ii) combustion of uncondensed gases obtained after condensation of said vapor-gas products formed in the steam thermolysis reactor or a combination thereof.
