  1. 1. Effect of powder spray drying on catalyst formulation in tablet form

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Kajsa Wahlgren; [2023]
    Nyckelord :Spray dryer; Catalyst; Powder; Flowability; Chemical engineering; Technology and Engineering;

    Sammanfattning : Heterogenous catalysts consist of a large surface area support material applied with the catalytic active phase, and the activity of a catalyst is often correlated to the surface area per volume. Support materials often need to be processed further to be optimal for specific processes. LÄS MER

  3. 2. Analysis of granulated carbide powder and how it affects pressing

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Maeva Anfossi; Emma Hjortzberg-Nordlund; Linnéa Lundemo Mattsson; [2023]
    Nyckelord :Cemented Carbide Tools; Pressing Agent; Flowability; Tap Density; Angle Of Repose; Hall Flow Time; Particle Size Distribution; Powder Rheometer; Compatibility; Hårdmetallverktyg; Pressmedel; Flytbarhet; Tapp Densitet; Rasvinkel; Hall Flödestid; Partikelstorleksfördelning; Pulverrheometri; Kompatibilitet;

    Sammanfattning : During the pressing of powder mixtures to make cemented carbide tools, the degree to which the powder spreads to fill the die and to which it compacts is uncertain. This leads to inconsistent dimensions and densities in the finished product. LÄS MER

  4. 3. Modeling and optimisation of a rotary kiln reactor for the processing of battery materials

    Master-uppsats, KTH/Kemiteknik

    Författare :Danial Khawaja; [2021]
    Nyckelord :Granular flow; rolling mode; suspension model; two-fluid model; multiphase flow; Granulärt flöde; rullningsläge; suspensions modell; tvåvätskemodell; flerfasmodell;

    Sammanfattning : Roterugnar är cylindriska kärl som används för att höja materials temperaturer i en kontinuerlig process som kallas för kalcinering. Roterugnar kan tillämpas i olika processer såsom reduktion av oxidmalm samt återvinning av farligt avfall. LÄS MER

  5. 4. Metal Powder Benchmarking

    Master-uppsats, KTH/Materialvetenskap

    Författare :Ananthakrishna Sajithkumar; [2021]
    Nyckelord :Selective laser melting; powder characterisation; flow behaviour; Selektiv lasersmältning; karakterisering av pulver; flödesbeteende;

    Sammanfattning : Metal  additive  manufacturing  technologies  are  widely  employed  in  the aerospace, automotive  and  medical  industries. Selective  laser  melting  is  a type  of  metal additive manufacturing process in which powders are consolidated layer by layer in a predefined pattern with the help of a laser beam to create a component.

  7. 5. Comparison of Methods for Measuring Powder Flowability

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Linnea Sternefält; [2021]
    Nyckelord :powder technology; pharmaceutical technology; engineering; Chemistry;

    Sammanfattning : Powders are widely used in pharmaceutical applications and understanding their nature is an important aspect of making successful formulations. Powder flowability describes the behaviour of powders and can be measured using several different methods. LÄS MER
