1. 11. Axial Mixing of Large Solids in Fluidised Beds – Modelling and Experiments

   Författare :Anna Köhler; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid-dynamic down-scaling; fluidised beds; magnetic particle tracking; solids mixing; semi-empirical modelling;

   Sammanfattning : Fluidisation is a technology commonly found wherever particulate solids are to be transported, mixed and/or reacted with a gas. At present, it is a widespread technology with applications ranging from the production of carbon nanotubes in the manufacturing industry to the conversion of solid fuels in the heat and power sector.

3. 12. NOx Formation in Rotary Kilns for Iron Ore Pelletization

   Författare :Rikard Edland; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rotary kiln; combustion chemistry; emissions control; Grate-Kiln process; Nitrogen oxides; NOx formation;

   Sammanfattning : The production of iron ore pellets is often performed in the so-called Grate-Kiln process. The aim of the process is to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. LÄS MER

4. 13. NOx formation in iron ore rotary kilns

   Författare :Rikard Edland; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rotary kiln; Grate-Kiln process; emissions control; combustion chemistry; Nitrogen oxides;

   Sammanfattning : Iron ore pellets are often produced using the so-called Grate-Kiln process, which is designed to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. The heat required for this process comes from the combustion of a pulverized fuel in a rotary kiln, involving the formation of a jet flame. LÄS MER

5. 14. Properties of modified starches and their use in the surface treatment of paper

   Författare :Anna Jonhed; Lars Järnström; Ann-Charlotte Eliasson; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface treatment of paper; hydrophobically modified starches; temperature-responsive starch; inclusion complexes; barrier properties; Surface engineering; Ytbehandlingsteknik; Chemical Engineering; Kemiteknik;

   Sammanfattning : The papermaking industry uses a large amount of starch each year, both as a wet-end additive and as a rheological modifier in surface sizing and coating colors. It is important to be able to reduce the amount of chemicals used in the papermaking and surface treatment process, to reduce costs and to make the process even more efficient. LÄS MER

7. 15. Electrokinetic devices from polymeric materials

   Författare :Katarina Bengtsson; Nathaniel D Robinson; Mats Fahlman; Jörg P. Kutter; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : There are multiple applications for polymers: our bodies are built of them, plastic bags and boxes used for storage are composed of them, as are the shells for electronics, TVs, computers, clothes etc. Many polymers are cheap, and easy to manufacture and process which make them suitable for disposable systems.
