  1. 1. Spherical Crystallization of Benzoic Acid

    Författare :Jyothi Thati; Åke Rasmuson; Luis Moreno; Eva Blomberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spherical agglomeration; Spherical agglomeration; Benzoic acid; Solubility phase diagram; Physico mechanical properties; Chemical engineering; Kemiteknik;

    Sammanfattning : Spherical agglomerates of benzoic acid crystals have been successfully prepared by drowning-out crystallization in three solvent partial miscible mixtures. Benzoic acid is dissolved in ethanol, bridging liquid is added and this mixture is fed to the agitated crystallizer containing water. LÄS MER

  3. 2. Wettability and Agglomeration Characteristics of Non-Metallic Inclusions

    Författare :Changji Xuan; Pär Jönsson; Lauri Holappa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wettability; non-metallic inclusion; agglomeration mechanism; attraction force; complex deoxidation; particle addition; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : In this thesis, both the wettability and the agglomeration characteristics of non-metallic inclusions in liquid iron/steel were studied by using both experimental results and thermodynamic considerations. The mechanisms of the wettability of different types of inclusions were discussed. LÄS MER

  4. 3. Particle Engineering by Spherical Crystallization:Mechanisms and Influence of Process Conditions

    Författare :Jyothi Thati; Åke Rasmuson; Stephane Veesler; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spherical agglomeration; Benzoic acid; Solubility; Phase diagram; Physico- mechanical properties size distribution; particle morphology and crushing strength; elastic recovery; compressibility ; Chemical engineering; Kemiteknik;

    Sammanfattning : Spherical agglomerates of benzoic acid crystals have been successfully prepared by drowning-out crystallization in three solvent partial miscible mixtures. Benzoic acid is dissolved in ethanol, bridging liquid is added and this mixture is fed to the agitated crystallizer containing water as the anti-solvent. LÄS MER

  5. 4. Study of Non-metallic Inclusion in Alloy 825

    Författare :Hans Kellner; Andrey Karasev; Pär Jönsson; Guozhu Ye; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 825; FeTi70R alloy; non-metallic inclusions; inclusion distribution; clusters; electromagnetic and gas stirring; ladle treatment; electrolytic extraction; stirring directions; Alloy 825; FeTi70R legering; icke-metalliska inneslutningar; inneslutnings fördelning; kluster; elektromagnetisk och gas omrörning; skänkugnsbehandling; elektrolytisk extraktion; omrörningshåll; Metallurgical process science; Metallurgisk processvetenskap; Steel Forming and Surface Engineering;

    Sammanfattning : It is well known that inclusions affect the properties of steels and alloys. Therefore, it is important to understand what type of inclusions that exist and how they behave and especially with a focus on large size inclusions. LÄS MER

  7. 5. Mechanical activation of clay : a novel route to sustainable cementitious binders

    Författare :Ilda Tole; Andrzej Cwirzen; Mirja Illikainen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; clay; sustainability; mechanical activation; ball milling; supplementary cementitious materials; alkali-activated materials; Byggmaterial; Building Materials;

    Sammanfattning : EU Sustainable Development Strategy planned to achieve improvement of life-quality by promoting sustainable production and consumption of raw materials. On November 2018, EU Commission presented a long-term strategy, aiming among others a climate-neutral economy by 2050. Cement production is contributing to 6-10% of the anthropogenic CO2 emissions.
