1. Lokalisering av framtidens stålproduktion
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystemSammanfattning : Stålindustrin är den industrisektor som har högst utsläpp i världen. Ståltillverkning tillskrivs cirka 8 % av världens totala C02-utsläpp. Från den utgångspunkten är behovet av djup avkarbonisering av stålindustrin är uppenbart. LÄS MER
2. The influence of particle size distribution on bio-coal gasification rate as related to packed beds of particles
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : This thesis is a part of a collaboration between Höganäs AB and Luleå University of Technology, aiming at replacing fossil process coal with bio-coal in their sponge iron process. The difference in gasification reactivity, i.e. LÄS MER
3. Usage of Natural Gas in Modern Steel-making : A Financial and Environmental Evaluation of Available Steel-making Technology in Sweden
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : A method of producing steel that is not used in Sweden today is direct reduction using natural gas, a method which could has enormous potential in the future of steelmaking. Historically, steelmaking prioritized productivity and profitability. LÄS MER
4. Life cycle assessment of coal based direct-reduced iron production in India
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The production of iron through direct reduction (Direct-Reduced Iron; DRI) involves the use of natural gas or coal to reduce iron ore to iron through carbothermic reactions at a temperature below its melting point, negating the need for a blast furnace as otherwise required. In India, around 25% of iron is produced through direct reduction. LÄS MER
5. Towards a fossil free steel sector : Conditions for technology transfer of hydrogenbased iron and steel in Europe
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : In order to meet the targets of the Paris Agreement, there is a need to significantly reduce emissions from energy-intensive industries, iron and steel included. One promising technology with the potential to reduce the emissions related to iron and steelmaking to basically none is direct reduction with fossil free hydrogen, which requires large amounts of fossil free electricity.
