Process for the treatment of a residual material containing hydrocarbons, in particular a sludge from rolling mills and / or a sludge sludge, in which the residual material is heated in a drying apparatus, preferably in motion, by indirect input of heat, and thus is released from hydrocarbons, possibly in common with other volatile components, in particular H2O, and hydrocarbons, eventually in common with the other volatile components, in particular with H2O, are at least partially removed from the container, in particular, is separated by aspiration, characterized in that in the drying apparatus, at a temperature of 400 ° C, a planned decomposition of the hydrocarbons is carried out, realizing that the decomposition of the hydrocarbons is carried out in the form of a splitting of the hard volatile hydrocarbons to form easily volatile hydrocarbons, preferably hydroc arboros with high pesomolecular to form hydrocarbons with low molecular weight, and by means of a regulated and / or controlled quantitative use - determined as regards the magnitudes of regulation: u composition of the resulting exhaust gas in the drying apparatus, and its temperature waste material treated in the drying apparatus, - of one or more of the following chemical auxiliary means: or oxygen, in particular in the form of mixtures of oxygen and inert gases, or air enriched with oxygen and / or with another oxygen carrier, or a solid and / or liquid and / or gaseous peroxide or hyperoxide, preferably hydrogen peroxide, or ozone. |
