Claims (1)

Способ относится к прямому восстановлению частицеобразного, содержащего оксид железа материала с псевдоожижением, риформинг-газ смешивают с образующимся при прямом восстановлении содержащего оксид железа материала колошниковым газом и в качестве восстановительного газа подают в зону восстановления с псевдоожиженным слоем. Для уменьшения потребности в энергии и исчерпывания потенциала восстановительного газа, как колошниковый газ, так и риформинг-газ подвергают отмывке от СО2 и в образующемся путем смешения колошникового газа с риформинг-газом восстановительном газе устанавливается содержание Н2 в пределах 45 - 75%, предпочтительно 50 - 65% и содержание СО в пределах 10 - 20%.The method relates to the direct reduction of a particle-like iron oxide-containing fluidized material, the reforming gas is mixed with the blast furnace gas formed during the direct reduction of the iron oxide-containing material, and as a reducing gas it is fed to the reduction zone with a fluidized bed. To reduce the energy requirements and exhaust the potential of the reducing gas, both the top gas and the reforming gas are washed from CO 2 and the content of H 2 is set in the range of 45 - 75% in the resulting gas produced by mixing the top gas with the reforming gas, preferably 50 - 65% and the content of CO in the range of 10 - 20%.
