  1. 1. Residual Products in the Steel Industry Used for Briquetting

    University essay from KTH/Materialvetenskap

    Author : Alexander Eriksson; Linn Isaksson; Jacob Lilliebjörn; [2023]
    Keywords : ;

    Abstract : This report looks at the implementation of briquetting in the Swedish steel industry. Briquetting is a process in which residual products are mixed and compressed into a brick-like body in order to be added to the melt in a furnace. This report investigates the type of materials commonly used in briquetting as of today. READ MORE

  3. 2. Electrolytic Reduction of Iron Oxides in Molten Salt with a Mineralogical Investigation of Magnetite Ore of Tapuli

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Elina Fernö; [2023]
    Keywords : Iron reduction; trace element analysis on magnetite ore; molten salt electrolysis; sodium hydroxide electrolyte; NaOH; greenhouse gas; carbon dioxide; CO2; green ironmaking; Järnreduktion; spårelementanalys på magnetitmalm; smältelektrolys; elektrolys i natriumhydroxid; NaOH; elektrolyt; växthusgas; koldioxid; CO2; grön järnframställning;

    Abstract : This master's thesis covers an investigation of the reduction behavior of different iron oxides when electrolytically reduced with molten salt electrolysis (MSE). The tested iron oxides were wüstite (FeO), hematite (Fe2O3), magnetite (Fe3O4) and magnetite ore concentrate from the Tapuli deposit in Pajala, Norrbotten, Sweden. READ MORE

  4. 3. Understanding the potential future capacity of distributing green steel solutions - current knowledge and future challenges

    University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Author : Heba Alwan; [2023]
    Keywords : Carbon dioxide CO2 ; greenhouse gas GHG emissions; Steelmaking fossil-free; direct hydrogen reduction; Sustainability transitions.;

    Abstract : Transitioning from the conventional steel process to a direct hydrogen reduction process in the steel industry is a significant step towards reducing carbon dioxide emissions and achieving greater sustainability. The process involves using hydrogen gas as a reducing agent instead of carbon to remove oxygen from the iron ore. READ MORE

  5. 4. Influence of coal particle sizes on the mechanical strength of iron-carbon briquettes : With focus on steelmaking applications

    University essay from KTH/Materialvetenskap

    Author : Daniel Zaharije Hodgson; Efe Karadag; Maxime Pierre Jean-Claude Saillen; [2022]
    Keywords : ;

    Abstract : Replacing fossil carbon materials with renewable biocarbon is one way to reduce the net carbon dioxide emissions of the iron and steelmaking industry. Carburization is an important application in the electric arc furnace (EAF), and is mostly achieved by adding fossil-based carbon materials into the melt today. READ MORE

  6. 5. The effect of thickness and compaction on the recovery of aluminium in recycling of foils in salt flux

    University essay from KTH/Materialvetenskap

    Author : Harald Philipson; [2020]
    Keywords : ;

    Abstract : In Norway, more than 40.000 tonnes of aluminum (Al) in food packaging goes to incineration annually. Recycling this waste would save more than 1.5 TWh of energy and several hundred thousand tonnes of CO2 emissions. READ MORE
