  1. 1. Effect of Refining on Softwood Pulp with Addition of Eucalyptus for Greaseproof Paper Production : Vacuum Dewatering in Laboratory Scale

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Anton Nordling; [2023]
    Nyckelord :Refining; beating; eucalyptus; greaseproof paper; degree of refining; vacuum dewatering; formation; air permeance; Malning; Eukalyptus; fettresistent papper; malgrad; vakuumavvattning; formation; luftpermeans;

    Sammanfattning : We are provided countless products from the forest industry and has been through many years. Paper, paper board, packaging materials and furniture to mention a few. A special type of paper used in food packaging for example, is greaseproof paper. LÄS MER

  3. 2. Improvements in Energy Efficiency of Vacuum Dewatering of Greaseproof Paper : Simulation of a Triple Vacuum Suction Box in Laboratory Scale

    Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik

    Författare :Björn Öman; [2023]
    Nyckelord :Vacuum dewatering; greaseproof paper; triple vacuum suction box; grammage; energy efficiency; dryness; Vakuumavvattning; greaseproofpapper; trippelvakuumsuglåda; ytvikt; energieffektivitet; torrhalt;

    Sammanfattning : Vacuum dewatering of paper is a heavily energy expensive process, even more so for greaseproof paper, which is one of the main products at Nordic Paper Seffle AB. Due to this being such an energy demanding process, improvements in the vacuum dewatering could save massive amounts of energy. LÄS MER

  4. 3. 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

    Nyckelord :Microfibrillated cellulose; MFC; waxy maize starch; rheology; temperature; viscosity; complex viscosity; stready shear viscosity curve; amplitude sweep; dry content; dynamic rotational rheometer; Mikrofibrillerad cellulosa; MFC; vaxartad majsstärkelse; reologi; temperatur; viskositet; komplex viskositet; flödeskurva; amplitudsvep; torrhalt; dynamisk reometer;

    Sammanfattning : Today, the focus lies on the state of the environment and how we can choose more sustainable alternatives to oil based materials. One material of interest is microfibrillated cellulose (MFC). LÄS MER

  7. 5. Dispersed bio-based binders as drop-in solution for non-woven industry

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Emma Ingo; [2021]
    Nyckelord :Dispersion; Modified Biopolymers; Non-Woven; Binders; Green Chemistry; Dispersion; Modifierade Biopolymerer; Non-Woven; Bindemedel; Grön Kemi;

    Sammanfattning : Sammanfattning på svenska: Målet med projektet var att utveckla ett system av disperserade bindemedel för non-wovenindustrin som inte förutsätter omfattande förändringar i befintliga processer. Bindemedlet ska vara biobaserat, bionedbrytbart och endast bestå av byggstenar som är matkontaktsgodkända av FDA och BFR. LÄS MER
