Estimating the term…
The invention relates to a method and a device for the thermal decomposition of an initial material, in particular, for the decomposition of meat and bone meal, oil sludges, for example, from cleaning tankers, autofluff (also called autofluffy), basic glycerin, for example, from biodiesel production, paint sludges from paint shops, contaminated soils, coated wood, and plastics such as plexiglass. According to the present method, organic initial materials are thermally decomposed very completely in nearly all cases. The very complete decomposition is achieved by adding foreign particles such as metal spheres to the initial material which is being thermally decomposed.

A method for decomposing an initial material, in particular an organic initial material, into gaseous, liquid and/or solid products by pyrolysis, characterized in that an initial material is moved in a container of a horizontal mixer together with foreign particles during the thermal decomposition, with the material of the foreign particles being neither thermally decomposed nor liquefied during the pyrolysis, wherein initial materials are supplied to the container of the horizontal mixer continuously, the gases produced in the container during pyrolysis are withdrawn continuously, the supply of initial materials is stopped when a predetermined filling level of the container is exceeded, and subsequent to that, solids are partially withdrawn from the container as soon as no gas can be withdrawn anymore.
