  1. 1. Investigation into Melting Characteristics of Hydrogen-Reduced Iron Ore Pellets

    University essay from KTH/Materialvetenskap

    Author : Hedda Pousette; [2019]
    Keywords : Iron Ore Pellets; Sulphur; Phosphorous; Slag; Hydrogen Gas; Järnmalmspellets; Svavel; Fosfor; Slagg; Vätgas;

    Abstract : What kinetic and thermodynamic characteristics are established in a melt of hydrogen-reduced iron ore pellets? The pellets contain self-fluxing slag components which upon melting form an initial slag. Refining capabilities of this slag, such as dephosphorization power, are investigated in a lab-scale vertical furnace. READ MORE

  3. 2. The Price, Quantity, and Welfare Impacts on the EU Following Increased Import Tariffs: An empirical estimation of 2018’s trade retaliation against the U.S.

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Sofie Andersson; [2019]
    Keywords : EU; U.S.; tariffs; trade; welfare losses; Business and Economics;

    Abstract : This paper explores the impacts of EU’s retaliatory tariffs towards the U.S. on prices, quantities, and welfare. Over the course of 2018, the Trump Administration imposed tariffs on EU steel and iron, to which the EU implemented counter measures of increased tariffs on U. READ MORE

  4. 3. Towards a fossil free steel sector : Conditions for technology transfer of hydrogenbased iron and steel in Europe

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Amanda Öhman; [2019]
    Keywords : hydrogen-based iron and steel; direct reduction; industry decarbonisation; energy transition; Multi-level perspective; technology transfer; vätgasbaserat järn och stål; direktreduktion; fossilutfasning i industrin; energiomställning; multinivåperspektiv; tekniköverföring;

    Abstract : 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.

  5. 4. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method

    University essay from KTH/Energiteknik

    Author : Aravind Ganesan; [2019]
    Keywords : syngas; Cobalt; Fischer-Tropsch; alcohols; hydrocarbons; syngas; kobolt; Fischer-Tropsch; alkoholer; kolväten;

    Abstract : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. READ MORE

  6. 5. Reduction of a Detailed Thermal Model Lumped Parameters Approach for an OSV Induction Motor

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Luca Roggio; [2019]
    Keywords : ;

    Abstract : This thesis work is dealing with a detailed thermal model for an open self ventilated inductionmachine with lumped parameters approach. The model is entirely built using as referencespublished articles. The thermal network is tested using both MATLAB for calculating theparameters and SimScape for simulations and validation. READ MORE
