  1. 31. Comparative analysis of different pyrolysis techniques by using kraft lignin : Jämförelse mellan olika pyrolys metoder

    Master-uppsats, Karlstads universitet

    Författare :Husam Abbas; [2020]
    Nyckelord :Pyrolysis;

    Sammanfattning : This thesis presents a comparison analysis between various pyrolysis techniques performed on kraft lignin. Numerous literature studies of pyrolysis techniques performed on kraft lignin are reviewed and analysed where different operation temperatures, catalysts and different heating methods are used to pyrolyze kraft lignin.

  3. 32. Carbon materials from biomass for supercapacitors

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Jaskaran Singh Malhotra; [2020]
    Nyckelord :Supercapacitors; Activated Carbon; Energy Storage; Biomass conversion; Electrochemical Energy Storage; Pyrolysis; Superkapacitatorer; Aktivt kol; Energilagring; Biomassa omvandling; Elektrokemisk energilagring; Pyrolys;

    Sammanfattning : The fast pyrolysis plant at RISE – ETC, Piteå produces carbon rich chars in bulk from various sources of biomass as feedstock. These in-house manufactured carbon rich chars were upgraded via pyrolysis as well as chemical activation using KOH to enhance their potential as an electrode material for supercapacitors. LÄS MER

  4. 33. Development of biochar in Sweden : A study on the agricultural effects of biocharthrough an international comparison

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ili Atalla; Gabriel Kurt; [2020]
    Nyckelord :Pyrolysis; Biochar; Carbon sink; Agricultural effects; Pyrolys; Biokol; Kolsänka; Jordbrukspåverkan;

    Sammanfattning : Biochar represents a new approach to fight global warming through its ability to reduce carbon dioxide emissions by carbon fixation. It has been proven to be efficient in increasing harvest through the effects of increasing WHC, pH level and the uptake of nutrients. LÄS MER

  5. 34. Vitalisering med biokol i urbana växtbäddar : befintliga tekniker på marknaden som kan implementeras

    Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Björn Skålberg; Jacob Stenlund; [2020]
    Nyckelord :biokol; biochar; växtbädd; pyrolys; jordförbättring; vitalisering;

    Sammanfattning : Biokol är en produkt med högt kolinnehåll. Upptäckten av biokol “Terra preta” kommer från Sydamerika där biokol var en restprodukt som visade sig ha mycket positiva effekter på växtligheten. LÄS MER

  7. 35. Fast Pyrolysis of Biomass in a Fluidized Bed for Production of Bio-oil and Upgradation by Ex-situ Catalytic Bed

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Samina Gulshan; [2019]
    Nyckelord :;

    Sammanfattning : Production of bio-oil from biomass is now becoming best substitute of fossil fuels in the transportation sector. Pyrolysis is one of the most promising route to produce bio-oil from biomass.  However, bio-oil needs to be upgraded due to presence of high percentage of oxygenated compounds. LÄS MER
