  2. 2. The effects of mixing on the enzymatic hydrolysis of lignocellulosic biomass

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Adnan Kadic; Lund University.; Lunds universitet.; [2017-05-11]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; softwood; spruce; enzymatic hydrolysis; mixing; viscosity;

    Abstract : Biorefining of lignocellulosic biomass into biofuels and chemicals can help replace fossil resources and decrease anthropogenic greenhouse gas emissions. This thesis is focused on the effects of mixing on the enzymatic hydrolysis of pretreated biomass. READ MORE

  4. 4. A Multi-Scale Approach To Adhesive Mixing

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Duy Nguyen; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive particle mixing; CFD simulation; multiscale; dry particle coating; regime map.; DEM simulation; dry powders for inhalation;

    Abstract : Adhesive particle mixing is a fundamental process in many applications, especially in dry powders for inhalation. Despite its importance, a mechanistic process description for designing the structure of interest is still lacking. READ MORE

  5. 5. Axial Mixing of Large Solids in Fluidised Beds – Modelling and Experiments

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Anna Köhler; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid-dynamic down-scaling; fluidised beds; magnetic particle tracking; solids mixing; semi-empirical modelling;

    Abstract : Fluidisation is a technology commonly found wherever particulate solids are to be transported, mixed and/or reacted with a gas. At present, it is a widespread technology with applications ranging from the production of carbon nanotubes in the manufacturing industry to the conversion of solid fuels in the heat and power sector.
