A fluid bed reactor, device to preheat keep gas and process for fluidificacao reaction of solid particles with gas of hot fluidificacao

摘要

A fluid bed reactor for treatment of refractory materials with a hot fluidizing gas and a method to use same. Both the refractory materials and the fluidizing gas are introduced from the top of the reactor. Unusually high reaction temperatures of up to 2000 DEG C. are maintained in the reaction chamber due to the presence of heating elements within the reactor and due to countercurrent heat transfer.
