1. Investigating the parameters that influence the behaviour of natural iron ores during the iron production process
Sammanfattning : In the iron production processes, sinters and pellets are mostly used as raw materials due to their consistency with respect to physical and chemical properties. However, natural iron ores, as mined, are rarely used directly as a feed material for iron processing. LÄS MER
2. Mineral Reactions and Slag Formation During Reduction of Olivine Blast Furnace Pellets
Sammanfattning : The present work focuses on mineral reactions and slag formation of LKAB olivine iron ore pellets (MPBO) subjected to reducing conditions in the LKAB experimental blast furnace (EBF). The emphasis is on olivine reactions with surrounding iron oxides. Many factors influence the olivine behaviour. LÄS MER
3. Theoretical Studies on CO2 Reduction Electrocatalysts
Sammanfattning : The atmospheric CO2 concentration has increased by more than 20% since 1980s and has now reached the highest level than at any point in the past 800 000 years. Electrochemical CO2 reductions are receiving particular in- terest as the apparatus are relatively easy to maintain and cheap to operate. LÄS MER
4. Enzymatic Reduction of Ketones
Sammanfattning : Methods have been studied for the production of chiral alcohols, which are of importance in organic synthesis of pharmaceuticals, agro-chemicals and fragrances, etc., through the enzymatic or microbial reduction of ketones. LÄS MER
5. Modeling and Model Reduction by Analytic Interpolation and Optimization
Sammanfattning : This thesis consists of six papers. The main topic of all these papers is modeling a class of linear time-invariant systems. The system class is parameterized in the context of interpolation theory with a degree constraint. LÄS MER
