Реферат: Direct iron-ore reduction process whereby an NH 3 -containing a gas feed (24a) is supplied to a gas reformer (25) and reformed therein so as to obtain a hydrogen-containing reducing gas (25a, 25b) which, at least in part, is supplied to a direct-reduction reactor (1) in which iron ore (2) is subjected to direct reduction with the reducing gas (25a, 25b) so as to obtain direct reduced iron (30) and whereby during the reforming of the hydrogen-containing reducing gas (25a), the NH 3 in the gas feed (24a) is subjected to the dissociation reaction 2 NH 3 — > N 2 + 3H 2 .
