2. 1. The Technology and Economy of Farm-Scale, High-Solids Anaerobic Digestion of Plant Biomass

   Author : Mattias Svensson; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; farm-scale; Bioteknik; farmhouse construction; Lantbruksteknik; Biotechnology; agricultural machines; kontroll av utsläpp; Agricultural engineering; Miljöteknik; pollution control; Environmental technology; Lantbruksekonomi; straw bed priming; stratified bed digesters; nitrogen recycling; greenhouse gases; Sweden; Agricultural economics; sequential single-stage fed-batch; ley crops; sustainability; wheat straw; sugar beet tops; crop residues; high-solids; economy; Anaerobic digestion; biogas upgrading;

   Abstract : Anaerobic digestion is a microbially mediated process occurring in nature in the absence of oxygen and other non-carbonaceous electron acceptors. The majority of the carbon of the organic matter degraded in the process is transformed into carbon dioxide and methane. READ MORE

4. 2. Production of Ethanol from Spruce at High Solids Concentrations - An Experimental Study on Process Development of Simultaneous Saccharification and Fermentation

   Author : Kerstin Hoyer; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ethanol; spruce; SSF; fermentation; enzymatic hydrolysis; lignocellulose; high solids;

   Abstract : Replacing fossil fuels by biofuels such as ethanol is considered a promising alternative to reduce greenhouse gas (GHG) emissions and mitigate climate change. Biofuels produced from lignocellulosic biomass, so-called second generation biofuels, result in decreased GHG emissions and limit competition with food and animal feed production. READ MORE

5. 3. Consolidation and Rheology at High Solids Content

   Author : Jerker Jäder; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

   Abstract : Paper and board are pigment coated in order to achieve a smooth surface, thereby enhancing the optical and printing properties. In the most frequently used technique, a metal blade is used for metering off the coating colour, which is typically applied by roll or jet application. READ MORE

6. 4. Hydraulic transport of mineral and ore products : friction losses of stratified flows at high solids concentrations

   Author : Åsa Sundqvist; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

   Abstract : The overall objective of the work presented in this thesis was to investigate the hydraulic transport of mineral and ore products with regard to friction losses in horizontal pipelines at high solids concentrations. In detail, the objectives are to present and examine experimental pilotscale and large-scale friction loss results, and to investigate the performance of a scaling relationship for stratified slurry flows with regard to the effects of pipe diameter and solids concentration.

7. 5. Waterborne Alkyd-Acrylic Hybrids with High Solids Content -Preparation and Properties-

   Author : Mehrnoush Jowkar Deriss; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biopolymers; Polymer technology; Polymerteknik;

   Abstract : The work presented in this thesis concerns the preparation, characterization and film formation of a waterborne alkyd-acrylic hybrid system with high solids content of about 80 %. The alkyd-acrylic hybrids were prepared by slowly adding a linseed oil alkyd to an acrylic latex dispersion under stirring. READ MORE
