  1. 1. Interaction of magnetite with soluble silicates and bentonite : implications for wet agglomeration of magnetite concentrate

    Författare :Xiaofang Yang; James McQuillan; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical Chemistry; Fysikalisk kemi; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Iron ore green pellets are produced by agglomeration of moist magnetite concentrates. The quality of green pellets is essential for the transportability and metallurgical benefits of the final product. LÄS MER

  3. 2. Impact of Ash on the Properties of Fluidized Bed Materials

    Författare :Robin Faust; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ash interaction; layer formation; agglomeration; fluidized bed; catalytic tar removal; oxygen carrying; bed material;

    Sammanfattning : The utilization of the fluidized bed technology offers the possibility of thermally converting a large variety of biogenic feedstocks. The characteristics of the bed material which is used in the process play a major role regarding the overall process performance. LÄS MER

  4. 3. Identification and Variation of some Functionality Related Characteristics of Pharmaceutically Relevant Solid Materials and their Effect on Product Performance

    Författare :Frauke Fichtner; Göran Alderborn; Åke Rasmuson; Peter Kleinebudde; Uppsala universitet; []
    Nyckelord :Pharmaceutics; Particle size distribution; Degree of agglomeration; Amorphous lactose; Matrix agglomerates; Drug release; Compactability; Tablet tensile strength; Particle fracture strength; Surfactant; Compression; Galenisk farmaci;

    Sammanfattning : The aim of this thesis was to identify some functionality related characteristics of pharmaceutically relevant solid materials and to study the effect of their variation on processing behaviour and product performance. For this purpose, particles with different characteristics were prepared under a variety of conditions by crystal agglomeration, wet granulation and spray drying. LÄS MER
