Iron ore reduction in a continuously operated multistage .

Iron ore reduction in a continuously operated multistage .

Industrial-scale fluidized bed processes for iron ore reduction (e.g., FIOR and FINMET) are operated by continuous feeding of ore, while laboratory tests are mostly performed under batchwise operation. The reduction behavior under continuous operation is influenced by both the residence time of the iron ore particles and the reduction kinetics, which is obtained by batch tests.

FCC reactors are recycle fluidized bed systems, which have highly-abrasive zeolite catalysts moving at extremely high linear velocities. Especially in areas where pipe-bends or hindrances are present, significant material loss of the reactor walls can occur. This presents a serious operational and safety problem for FCC reactor operators.
