Abstract

Способ прямого восстановления металлосодержащего материала включает: подачу твердого углеродсодержащего материала и кислородсодержащего газа в псевдосжиженный слой в первом реакторе (3) и получение тепла вследствие реакции в псевдосжиженном слое между кислородсодержащим газом и твердым углеродсодержащим материалом и другими твердыми материалами и газами, которые поддаются окислению, и выведение из реактора потока горячих отходящих газов, который содержит захваченные твердые материалы; и подачу металлосодержащего материала в псевдосжиженный слой в другом реакторе и подачу потока горячих отходящих газов, содержащий захваченные твердые материалы, из первог
