Abstract
Calcination of one of the volatile compounds is brought about in a first contacting column, in which the material is driven and put into suspension by an oxidizing gas stream, while being brought therein to a sufficiently high temperature, and the gaseous products desorbed in this first column are re-adsorbed by cooling in a second contacting column. This process applies principally to the regeneration of particles of alumina which have absorbed tars and compounds containing fluorine.
