Abstract

L'invention concerne un procédé ainsi qu'un dispositif de retraitement du produit de fond carboné formé lors de la gazéification de combustibles fossiles carbonés selon le procédé Winkler à haute température (HTW), en-dessous du lit fluidisé, dans le sens de la pesanteur. L'objectif est d'atteindre une oxydation plus importante avec des moyens simples, afin d'accroître la conversion du carbone dans les gazéificateurs HTW. Pour cela, selon l'invention, on achemine un agent oxydant, en le soumettant à l'action d'éléments en céramique à pores ouverts (15-20) tels que des briques de balayage de gaz, des céramiques expansées ou similaires, dans un oxydateur de produit de fond (2).
