  1. 1. Pyrolysis of Municipal Sewage Sludge to get a phosphorus rich char residue for soil improvement

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Shahin Shamim; [2023]
    Nyckelord :Sewage Sludge-Phosphorus-Pyrolysis- Heavy metals; Cadmium; Lead; Nickle; Copper; Chromium; Zinc; Biochar; Heating value; Fertilizer- Thermal conversion;

    Sammanfattning : Sewage sludge is a byproduct of wastewater treatment plants. It is a kind of waste. however, it contains several valuable nutrients like phosphorous and nitrogen that are used to rich the soil as a fertilizer compound. LÄS MER

  3. 2. Hydrogen production from automotive waste via integrated plasma gasification and water gas shift.

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

    Författare :Marco Occhinero; [2019]
    Nyckelord :;

    Sammanfattning : The growing amount of landfilled waste could pose a problem in many parts of the world due to the scarcity of landfilling space and environmental threats. In particular, automotive shredder residue (ASR) waste, a by-product of the dismantling of End of Life Vehicles (ELVs), has been proven to represent an issue in particular in the EU, where countries are struggling to compel to the directives that regulate this type of waste.

  4. 3. APPRAISAL OF FOOD RESIDUE (WASTE) BASED FUEL BRIQUETTES IN DOMESTIC COOKING APPLICATIONS: A CASE STUDY OF UGANDA

    Master-uppsats, Högskolan i Gävle/Energisystem

    Författare :WINFRED KAKOOZA ATEGEKA; [2017]
    Nyckelord :;

    Sammanfattning : The research focuses on developing and evaluating the performance of low cost, low technology food residue based fuel briquettes as an alternative to the widespread use of wood fuels (charcoal and firewood) for domestic cooking applications. In view of the declining accessibility of wood fuels, inadequate electrification coverage and ever-rising prices of cooking gas and kerosene in Uganda, harnessing energy from within reach, alternative sustainable energy sources such as food residues has been regarded as a viable solution to domestic cooking energy.

  5. 4. Slow pyrolysis in Brista : AN EVALUATION OF HEAT AND BIOCHAR PRODUCTION IN SWEDEN

    Master-uppsats, KTH/Energiteknik

    Författare :Erik Jonsson; [2016]
    Nyckelord :;

    Sammanfattning : This study is an analysis of the potential to have a slow pyrolysis power plant in Brista, Sweden. The study is investigating current technologies available and research and application of the pyrolysis products from the process. Pyrolysis has been known for over thousands of years. LÄS MER

  7. 5. Influence of Potassium on Gasification Performance

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Hepa Rasol; [2016]
    Nyckelord :Biomass; pyrolysis; steam and CO2 gasification; fluidized bed reactor; alkali metals; reaction rate; reactivity; GC- MS; TGA; bio- char and bio- tar;

    Sammanfattning : To release energy from chemically stored energy in the biomass was the new investigation in recent years. Utilizing of biomass for this purpose occur in two different ways, directly by burning (combustion) the biomass and indirectly by pyrolysis process which will convert the biomass to three main products, bio- tar, bio- char and synthetic gas.
