• Densification of Biocarbon and Its Effect on CO2 Reactivity 

      Kaffash, Hamideh; Tangstad, Merete; Surup, Gerrit Ralf (Peer reviewed; Journal article, 2021)
      Charcoal is an interesting reducing agent because it is produced from biomass which is renewable and does not contribute to global warming, provided that there is a balance between the felling of timber and growth of trees. ...
    • Dissolution kinetics of carbon materials in FeMn 

      Kaffash, Hamideh (Doctoral theses at NTNU;2019:226, Doctoral thesis, 2019)
      Submerged electric arc furnace (SAF) is the main process for industrial production of ferroalloys, in which metal oxides are reduced by carbon. To decrease the production cost and reduce the CO2 emissions, a variety of ...
    • Factors influencing dissolution of carbonaceous materials in liquid Fe– Mn 

      Kaffash, Hamideh; Tangstad, Merete (Peer reviewed; Journal article, 2020)
      Carbon dissolution from four types of metallurgical cokes and graphite was investigated by using immersion rods in a resistance furnace to clarify the influence of factors governing the rate of carbon dissolution from ...
    • Wettability of cokes by Fe-Mn melt 

      Kaffash, Hamideh; Xing, Xing; Tangstad, Merete (Peer reviewed; Journal article, 2020)
      Four metallurgical cokes were heat treated at 1250 °C to 1550 °C in argon atmosphere. The influence of heat treatment on the microstructure of metallurgical cokes was characterized using X-ray diffraction and Raman ...
