2. Qualitative and Quantitative Analysis of Biodiesel Deposits Formed on a Hot Metal Surface
Master-uppsats, Institutionen för fysik, kemi och biologi; Tekniska högskolanSammanfattning : This thesis aims to investigate the formation of deposits from thermally degraded biodiesel on a hot metal surface under the influence of sodium or copper contaminations. Biodiesel or Fatty Acid Methyl Esters (FAMEs) is a widely utilized biofuel with the potential to replace fossil fuels, however, issues regarding the thermal and oxidative stability prevent the progress of biodiesel for utilization as vehicle fuel.

3. Biogaspotential från organiska industriavfall i södra Brasilien : En studie av effekterna vid satsvis tillsats av glycerin till en pågående rötningsprocess
Kandidat-uppsats, Sektionen för ekonomi och teknik (SET)Sammanfattning : I såväl Brasilien som runt om i världen finns stora mängder organiskt avfall som skulle kunna utnyttjas på ett bättre sätt. Många potentiella substrat för biogasproduktion deponeras, eldas upp eller komposteras utan att den energi som skulle kunna utvinnas vid denna process tas tillvara. LÄS MER
4. An Assessment of Biofuels and Synthetic Fuels as Substitutions of Conventional Diesel and Jet Fuels
Magister-uppsats, Institutionen för fysik, kemi och biologiSammanfattning : Today, a majority of the world’s energy need is supplied through sources that are finite and, at the current usage rates, will be consumed shortly. The high energy demand and pollution problems caused by the widespread use of fossil fuels make it increasingly necessary to develop renewable energy sources of limitless duration with smaller environmental impact than the traditional energy sources.
