Process for reprocessing waste materials or the like by pyrolysis, and subsequent further processing of the pyrolysis oil

摘要

In a process for further treatment of carbonisation products, which are obtained in the carbonisation of waste materials, by liquid-phase hydrogenation in the presence of a disposable catalyst and/or disposable catalyst support, problematic wastes such as plastic wastes, hydrocarbon-contaminated residues, contaminated soils, biomasses and waste sludges, which preclude disposal in a landfill, are to be treated by a suitable process in such a way that no pollution of the environment by polycyclic hydrocarbons and/or chlorinated hydrocarbons is to be feared. The treatment of the problematic wastes is effected by carbonisation and subsequent further processing of the carbonisation products by liquid-phase hydrogenation. …??The disposable catalyst and/or disposable catalyst support or additive used is an internally or externally arising carbonisation coke or lignite coke which can have been impregnated with catalytically active metals or salts thereof. …??The process is suitable for the treatment of problematic hydrocarbon-containing wastes. Furthermore, the products obtained can, as products of value, be further utilised.
