  1. 1. Incorporation of Plasticizers through Refining into Wood Pulp : A Potential Route For Bio-based Thermoplastic Materials

    University essay from KTH/Materialvetenskap

    Author : Victor Eric Pierre Chartrain; [2023]
    Keywords : Cellulose; Paper; Plasticizer; Mechanical Refining; Cellulosa; Papper; Mjukgörare; mekanisk bearbetning;

    Abstract : Fibers are interesting materials alternative to replace conventional fossil-based plastics, as they are bio-based and do not lead to CO2 emissions. Due to their limited ductility, it is difficult to use them to make complex three-dimensional shapes. READ MORE

  3. 2. Development of pulp fiber charge in oxygen delignification of softwood

    University essay from KTH/Fiber- och polymerteknologi

    Author : Jiahao Mai; [2021]
    Keywords : fiber; fiber charge; fine content; oxygen delignification; softwood; fiber; fiberladdning; finmaterial; syrgasdelignifiering; barrved;

    Abstract : Esteves et.al. 2020 visade att syrgasdelignifiering ökar den totala fiberladdningen men leder inte alltid till ökad pappersstyrka. Denna studie syftar till att undersöka hur fiberladdning påverkar massans egenskaper. READ MORE

  4. 3. Pulp compositions and their influence on the production of dialcohol cellulose

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Viktoria Carlsson; [2020]
    Keywords : ;

    Abstract : The characteristics of products made from pulp can be modified through different methods. If the pulp is refined either laboratory or industrially, the fibres in the pulp become more flexible and therefore creates stronger bonds to each other, which results in a final product with a higher strength.

  5. 4. The potential of increased efficiency and power for a turbocharged PFI-SI engine through variable valve actuation and DEP

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Michael Nilsson; Jim Larsson; [2015]
    Keywords : Technology and Engineering;

    Abstract : New legislation involving emissions from internal combustion engines are pushing the manu-facturers to develop new technology faster than ever before with the amount of greenhouse gases. To meet the standards new concepts need to be developed with lower fuel consumption and emissions. READ MORE

  6. 5. Experimental comparison of DI and PFI in terms of emissions and efficiencyrunning Ethanol-85

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Daniel Ottosson; Konstantinos Zioris; [2014]
    Keywords : ;

    Abstract : It has in recent year become more and more important to find an alternative to fossil fuel in our vehicles due to the increasing fuel price and to reduce their negative impact on the environment. One alternative is already in widespread use around the world, namely ethanol. READ MORE
