  • This invention relates to the pyrolysis and/or gasification of material, in particular of material such as municipal solid waste containing a mixture of organic material and metals.
  • Gasification and pyrolysis of organic matter are known techniques in which the material is heated in the absence of oxygen (pyrolysis) or in a low oxygen environment (gasification) to produce syngas.

  • a carbonic residue remains together with inert ash like materials and the non organic matter, e.g. glass, metal etc.
  • the carbonic residue is a char or coke like substance referred to collectively herein as char.
  • this char still contains a recoverable energy, which can be recovered through gasification reactions in which oxygen is consumed. These take place at high temperatures and due to the temperature and the oxygen present tend to oxidise any metals present within the remaining material. This degrades the metal which, if preserved in good condition can be recovered and recycled. Accordingly systems that perform these processes are running at a lower than may be expected total efficiency as either the energy is trapped in the char, or the recoverable high value meals (e.g. aluminium) become oxidised and are either non recyclable or have their value significantly degraded due to the oxidation.

Abstract

La présente invention concerne un appareil de pyrolyse ou de gazéification de matériau contenant un contenu organique. L'appareil comprend un four (10) monté pour une rotation sur au moins un support (12, 14). Le four (10) comprend une chambre (16) de traitement principale, destinée à chauffer le matériau dans une atmosphère contenant peu ou pas d'oxygène, afin de gazéifier ou de pyrolyser son contenu organique. L'invention concerne également une chambre (18) de traitement secondaire, destinée à recevoir du matériau traité de la chambre (16) de traitement principale. Un séparateur (22) à courant de Foucault est placé près ou dans la chambre (18) de traitement secondaire et il est situé de sorte que, pendant que le four tourne, le matériau dans la seconde chambre de traitement passe devant à plusieurs reprises. Le séparateur (22) à courant de Foucault est orienté de sorte que, en cours d'utilisation, il éjecte les métaux non ferreux de la chambre (18) de traitement secondaire.
