• Pre-reduction Behaviour of Manganese Ores in H2 and CO Containing Gases 

      Ngoy, Didier; Dmitry, Sukhomlinov; Tangstad, Merete (Peer reviewed; Journal article, 2020)
      This paper presents results of a study conducted on the pre-reduction of Assmang and Comilog ores with gases of CO+CO2 and CO+H2+CO2 up to 1 000°C. Non-isothermal experiments were carried out in a vertical thermogravimetric ...
    • Steam Reforming of Methane on Sponge Iron: Influence of GasComposition on Reaction Rate 

      Ramos Ribeiro, Tiago; Neto, João Batista Ferreira; Poco, Joao G R; Takano, Cyro; Kolbeinsen, Leiv; Ringdalen, Eli (Peer reviewed; Journal article, 2020)
      Direct Reduction processes use gases (CO and H2) for iron reduction and production of sponge iron or direct reduced iron (DRI). The generation of this gas occurs through methane reforming, which can be done in a reformer ...
