Abstract

On utilise un mélange de gaz chauffé à haute température obtenu au moyen d'un brûleur d'oxygaz, de mélange air/combustible enrichi en oxygène ou d'air /combustible, pour dévolatiliser et oxygéner partiellement une charge carbonée et produire du carbone actif résiduel utilisable dans des applications requérant du charbon actif. L'utilisation de gaz chauds et d'une charge carbonée de base permet de réduire les équipements, et de produire le charbon actif sur ou au voisinage de lieux d'utilisation tels que par exemple les chaudières servant à réduire les émissions de mercure de certaines fumées industrielles.
