摘要： An apparatus for reducing a metalliferous material in a fluidized bed includes a vessel for containing the fluidized bed, a mechanism for supplying the metalliferous material, a solid carbonaceous material, an oxygen-containing gas, and a fluidizing gas into the vessel for forming the fluidized bed in the vessel. The oxygen-containing gas supply mechanism includes one or more than one oxygen-containing gas injection lance having a lance tip with an outlet that is positioned for injecting the oxygen-containing gas in a downward flow into the vessel within a range of plus or minus 40° to the vertical.

摘要： A direct reduction process for a metalliferous material includes supplying the metalliferous material, a solid carbonaceous material, an oxygen-containing gas, and a fluidizing gas into a fluidized bed in a vessel and maintaining the fluidized bed in the vessel, at least partially reducing metalliferous material in the vessel, and discharging a product stream that includes the partially reduced metalliferous material from the vessel. The process comprises (a) reducing the metalliferous material in a solid state in a metal-rich zone in the vessel; (b) injecting the oxygen-containing gas into a carbon-rich zone in the vessel with a downward flow in a range of ±40° to the vertical and generating heat by reactions between oxygen and the metalliferous material (including metallized material), the solid carbonaceous material and other oxidizable solids and gases in the fluidized bed, and (c) transferring heat from the carbon-rich zone to the metal-rich zone by movement of solids within the vessel. The metal-rich zone is formed in a lower section of the vessel and the carbon-rich zone is an intermediate section below an upper section of the vessel. Oxygen-containing gas is injected into a central region of the vessel.

摘要： A direct reduction process for a solid metalliferous material having a particle size distribution that at least in part contains micron sized particles includes supplying the metalliferous material, a solid carbonaceous material, an oxygen-containing gas, and a fluidizing gas into a fluidized bed in a vessel and maintaining the fluidized bed in the vessel, at least partially reducing metalliferous material in the vessel, and discharging a product stream that comprises the partially reduced metalliferous material from the vessel. The process includes (a) establishing and maintaining a carbon-rich zone within the fluidized bed; (b) passing metalliferous material, including metallized material (which term includes partially metallized material), through the carbon-rich zone; and (c) injecting the oxygen-containing gas into the carbon-rich zone and oxidizing metallized material, solid carbonaceous material and other oxidizable solids and gases and causing controlled agglomeration of particles.

摘要： A direct reduction process for a metalliferous material includes supplying a solid carbonaceous material and an oxygen-containing gas into a fluidized bed in a first vessel and generating heat by reactions between the oxygen-containing gas and the solid carbonaceous material and any other oxidizable solids and gases in the fluidized bed and discharging a hot off-gas stream containing entrained solids. The process also includes supplying the metalliferous material to a fluidized bed in a second vessel and supplying the hot off-gas stream containing entrained solids from the first vessel to the fluidized bed in the second vessel and partially reducing the metalliferous feed material in the solid state in the fluidized bed and discharging a product stream of partially reduced metalliferous material and an off-gas stream containing entrained solids.
