Abstract

L'invention porte sur un appareil de production compact et d'un maniement aisé servant à produire du carbone exempt d'oxydes à partir de substances organiques. Lesdites substances sont placées dans un récipient étanche spécial que l'on porte dans une chambre de carbonisation à environ 350 °C après l'avoir fait passer par la chambre frontale de préparation de l'appareil. On retire ensuite le récipient en passant par une chambre dorsale de préparation et on le laisse refroidir dans l'atmosphère ambiante jusqu'à environ 100 °C. On extrait alors le carbone du récipient, et on l'introduit dans un broyeur/séparateur magnétique qui le sépare en carbures et en mélange de métaux. On obtient ainsi du carbone exempt d'oxydes.
