Abstract: Two zone (11, 12; 21, 22; 31, 32; 41, 42) fluidized bed reactor (10, 20, 30, 40), wherein the upper zone (11, 21, 31, 41) presents a different section than the lower zone (12, 22, 32, 42). In one of the two zones (11, 12; 21, 22; 31, 32; 41, 42), a zone of reducing atmosphere is created and, in the other zone, a zone of oxidising atmosphere is created. In a preferred embodiment, the section of the upper zone (11, 21, 31, 41) is larger than that of the lower zone (12, 22, 32, 42), creating a reducing atmosphere in the upper zone (11, 21, 31, 41) and an oxidising atmosphere in the lower zone (12, 22, 32, 42). Rows of flow distributor tubes exist in the upper zone (11, 21, 31, 41) to avoid the appearance of dead zones.
