ABSTRACT:
The capacity and effectiveness of a fluidized multi-bed process for the direct reduction of broad size-range metallic oxides, such as ion oxide particles, can be materially improved by feeding the large-size particles into the uppermost zone and the fine-particle material such as bag dust to the lowest zone of a multiple bed reducer. The larger particles in the upper zones tend to restrain the fine particles from being carried out of the reducer by upwardly flowing reducing gas. In the lower zone location, complete reduction of the fine oxide particles is much more effective, as the reaction is initiated by the fresh reducing gas, which is normally high purity hydrogen.
