Abstract

The present invention relates to a method for treating carbonaceous materials by steam thermolysis, comprising: shredding carbonaceous waste materials; introducing the shredded carbonaceous waste materials into a reactor heated by combustion gases, gases laden with steam being introduced into the reactor so as to heat said shredded carbonaceous waste materials to a temperature between 200 and 700° C. during a steam thermolysis reaction; 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 products; separating the condensate obtained from said condensation into water containing residual hydrocarbons and into oil, and the water from the condensate being used as a source of heat energy for the reactor. The present invention also relates to a device for implementing the invention.

Abstract

The present invention relates to a method for treating carbonaceous materials by vapor thermolysis, which includes: grinding carbonaceous material waste; feeding the ground carbonaceous material waste into a reactor heated by combustion fumes, fumes loaded with water vapor being fed inside the reactor such as to heat said ground carbonaceous material waste to a temperature of 200 to 700°C during a vapor thermolysis reaction; cooling the combustion fumes to a temperature of 200 to 450°C and discharging same; and discharging the vapor/gas materials, formed in the reactor by vapor thermolysis, outside the reactor, then condensing same and separating the condensate resulting from said condensation in water containing residual hydrocarbons and in oil, the water from the condensate being used as a power source for heating the reactor. The present invention also relates to a device allowing the invention to be implemented.
