  1. 1. Waste-to-Energy : A study on Reaction Kinetics of Tropical Wood Sawdust

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

    Författare :Bertrand Asongwe Tita; [2016]
    Nyckelord :Tropical biomass; Thermo-gravimetric Analysis TGA ; reaction kinetics; pyrolysis;

    Sammanfattning : The reaction kinetics of Iroko and Mahogany were studied using TGA. The pyrolysis process was achieved using six different heating rates of 2,5,8,12,15 and 20˚C. A 15˚C/min heating rate was used for gasification in steam at different temperatures while varying the concentrations of nitrogen and steam in the process. LÄS MER

  3. 2. Effect of Alternative Fuels on SCR Chemistry

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemivetenskap (CHE)

    Författare :Simin Faramarzi; [2012]
    Nyckelord :SCR; urea; Adblue; additives; alternative fuels;

    Sammanfattning : In the time line of world industrial age, the most important era begins in the late 18th century when the use of fossil fuels was growing intensively. This approach has continued and developed up to the 20th century. Besides, this trend has had side effects like polluting environment. LÄS MER

  5. 4. Biodegradable Composites : Processing of thermoplastic polymers for medical applications.

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Behzad Damadzadeh; Hamideh Jabari; [2009]
    Nyckelord :poly lactic acid; poly glycolic acid; microcompounder; in-vitro degradation; biomedical application; hydroxy appetite hap ; tricalcium phosphate tcp ; bioactive glass bag ; bioceramic; medical composite; differential scanning calorimetry dsc ; inherent viscosity; termogravimetric analysis tga ; scanning electron microscopy sem ; biodegradable composite;

    Sammanfattning : Despite the recent development in PLA and PLGA based medical devices, there are still needs to further improve the mechanical performance of bioresorbable medical implants and their bioactivity. This is normally done by optimizing the filler compositions in selected groups ofbiodegradable polymer matrices. LÄS MER
