  1. 11. The transition of reaction-to-fire behavior from biomass to corresponding biochar

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jacob Johansson; [2023]
    Keywords : biochar; biomass; heat release rate; reaction-to-fire;

    Abstract : As of now, the environmental issue is very topical and there is also an underutilization of different biological material where these can be used in ways that are typically not thought of. One way to increase the degree of utilization is to convert various biomasses such as natural rubber, olive pits, wood chips, and reed pellets into biochar. READ MORE

  3. 12. The Effect on Mechanical Properties in Biochar Replaced Cement & Aggregate in Concrete Before and After Fire Exposure

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Felix Hansen; Mathias Berglund; [2023]
    Keywords : Biochar; Concrete; Sintering; Fire; Mechanical properties; Sustainability; Cement; Biochar in concrete; Building industry; Concrete exposed to fire.; Biokol; Betong; Sintring; Eld; Mekaniska egenskaper; Hållbarhet; Cement; Biokol i betong; Byggindustri; Brandexponerad betong.;

    Abstract : Concrete is good as a construction material regarding fire and its properties regarding strength. However, the concrete expands and cracks due to fire resulting in structural damage. According to the literature the concrete usually loses its strength during and after fire exposure due to themechanical and physical changes. READ MORE

  4. 13. Recycling end-of-life silicon PV panel with molten salt bath

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Liying Yu; [2023]
    Keywords : ;

    Abstract : Solar energy is recognized as a clean way to produce electricity. Solar PV's installed capacity is increasing in recent years. However, a PV panel has a 25-year lifespan on average. In actuality, 95% of the mass of PV components can be recycled. READ MORE

  5. 14. Experimental study on the effect of rocket nozzle wall materials on the stability of methane

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Thomas L. Holmboe; [2023]
    Keywords : Methane; pyrolysis; catalysis; nickel; coke deposition; chemical modelling; GRI3.0; rocket nozzle; regenerative cooling;

    Abstract : There has recently been an increased interest in methane as a rocket propellant due to its physical properties as well as the possibility of in-situ resource utilization in places like Mars. As part of ESA’s Future Launcher Preparatory Program, KTH in cooperation with GKN Aerospace has started the MERiT program, which seeks to study the characteristics of methane under conditions found in rocket nozzle cooling channels.

  6. 15. INVESTIGATION OF PHOSPHORUS SORPTION BY SEDIMENT DERIVED BIOCHAR - A LITERATURE REVIEW

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Christina Henricson; [2023]
    Keywords : ;

    Abstract : As excess phosphorus in water bodies causes eutrophication, biochar can be used as an adsorbent to remove phosphorus from water, thus increasing the circularity of phosphorus in the society. This literature review is a summary of recent research on optimised uptake of phosphorus by sediment derived biochar. READ MORE
