1. Negative Emission from Electric Arc Furnace using a Combination of Carbon capture and Bio-coal
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Steel is one of the most essential metals in the world, and it plays a vital role in various industries. The growing demand for steel has resulted in increased CO2 emissions, with the steel industry contributing to approximately 7% of global emissions of carbon dioxide. LÄS MER
2. Minskat CO2 avtryck i råstål genom en ökad andel skrot i konvertern
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Stålindustrin är kraftigt energi och utsläppsintensiv och står för upp till cirka 7% av de globala 𝐶𝑂2-utsläppen. Den huvudsakliga utsläppskällan utgörs av masugnsprocessen där järnmalm reduceras till råjärn med hjälp av fossilt kol i den malmbaserade processvägen. LÄS MER
3. Techno-economic evaluation of hydrochar via hydrothermal carbonisation of organicresidues
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : This thesis has investigated the techno-economic feasibility of upgrading the sludge from a chemical pulp mill to hydrochar via hydrothermal carbonization (HTC). The intended use of the hydrochar was to replace fossil coal within metallurgical applications in the iron and steel industry. LÄS MER
4. Influence of coal particle sizes on the mechanical strength of iron-carbon briquettes : With focus on steelmaking applications
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : 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. LÄS MER
5. SWOT-PESTEL Study of Constraints to Decarbonization of the Natural Gas System in the EU Techno-economic analysis of hydrogen production in Portugal : Techno-economic analysis of hydrogen production in Portugal
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The exigent need to address climate change and its adverse effects is felt all around the world. As pioneers in tackling carbon emissions, the European Union continue to be head and shoulders above other continents by implementing policies and keeping a tab on its carbon dependence and emissions.
