1. 1. Synthesis and modification of monodisperse polymer particles for chromatography

   Författare :Fredrik Limé; Knut Irgum; Harald D. H: Stöver; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer particles; photoinitiation; precipitation polymerization; styrene; divinylbenzene; atom transfer radical polymerization; liquid chromatography; Analytical chemistry; Analytisk kemi;

   Sammanfattning : Liquid chromatography is an analytical technique that is constantly facing new challenges in the separation of small molecules and large biomacromolecules. Recently the development of ultra high pressure liquid chromatography has increased the demand on sturdy particles as stationary phase. LÄS MER

3. 2. Traditional lime mortar and plaster : Reconstruction with emphasis on durability

   Författare :Kristin Balksten; Tor Broström; Britt-Marie Steenari; Thorborg Konow von; Chalmers Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lime plaster; lime mortar; masonry; craftsmanship; pore structure; frost resistance; historic mortar; Conservation HGO ; Kulturvård HGO ;

   Sammanfattning : Lime mortar and plaster have been investigated with the aim to improve the knowledge on how to make them as durable as before the cement technology was developed. The background was the durability problems experienced for newly produced lime plaster on the medieval churches on the island of Gotland, Sweden. LÄS MER

4. 3. Sintering in the Kraft Pulp Mill - Studies in the Rotary Kiln and Recovery Boiler

   Författare :Josefina Lindblom; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sintering; recovery boiler dust; recovery boiler; solid state diffusion; rotary kiln; lime mud; lime; sintering model; specific surface area;

   Sammanfattning : The conversion of black liquor to white liquor is carried out in the chemical recovery system, which is made up of several units; in two of them, i.e. the recovery boiler and the rotary kiln, sintering plays an important role. LÄS MER

5. 4. Study on the dissolution of lime and dolomite in converter slag

   Författare :Tengfei Deng; Sichen Du; Takeshi Yoshikawa; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dissolution; lime; limestone; dolomite; converter slag;

   Sammanfattning : In the present study, the dissolution mechanism and rate of lime, limestone and dolomite in converter slag was studied. Lime dissolution in stagnant slag was studied first and dissolution of lime, limestone and dolomite under forced convection were carried out by new experimental setup. LÄS MER

7. 5. Phase chemistry in process models for cement clinker and lime production

   Författare :Bodil Hökfors; Rainer Backman; Bo Björkman; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process modelling; phase chemistry; cement clinker; lime; sustainability; CO2; energy;

   Sammanfattning : The goal of the thesis is to evaluate if developed phase chemical process models for cement clinker and lime production processes are reliable to use as predictive tools in understanding the changes when introducing sustainability measures.The thesis describes the development of process simulation models in the application of sustainability measures as well as the evaluation of these models.
