Abstract

Oppfinnelsen vedrører en fremgangsmåte og et anlegg for varmebehandling av faststoffer som inneholder titan. For dette formål oppvarmes de finkornede faststoffer til en temperatur på 700 til 1000?C i en reaktor (4) med sirkulerende fluidisert lag og tømmes delvis ut fra reaktoren (4) sammen med avgasser inn i en nedstrøms separator (9). I separatoren separeres faststoffene fra avgassene og resirkuleres til reaktoren (4) i det minste delvis og/eller fasevis. Ifølge oppfinnelsen gjennomføres varmebehandlingen under reduserende betingelser.The invention relates to a method and a plant for the heat treatment of solids containing titanium. To this end, the fine-grained solids are heated to a temperature of 700 to 1000 ° C in a circulating fluidized bed reactor (4) and partially discharged from the reactor (4) together with exhaust gases into a downstream separator (9). In the separator, the solids are separated from the exhaust gases and recycled to the reactor (4) at least partially and / or in phases. According to the invention, the heat treatment is carried out under reducing conditions.
