1. Utilization of Forest Residue through Combined Heat and Power or Biorefinery for Applications in the Swedish Transportation Sector : a comparison in efficiency, emissions, economics and end usage
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : Sweden has the goal of reaching a fossil independent transportation sector by 2030. Two ways to reach the goal is to increase the use of electric vehicles or produce more biofuels. Both alternatives could be powered by forest residue, which is an underutilized resource in the country. LÄS MER
2. CLIMATE PERFORMANCE OF BIOFUELS : PRODUCED FROM FOREST RESIDUE HARVESTED IN SWEDEN
Kandidat-uppsats, KTH/Industriell ekologiSammanfattning : Biofuels produced from forest residues are much discussed in a Swedish context, among other things due to concerns for climate change. However, the undertaking of climate performance calculations is not an exact science. LÄS MER
3. Atmospheric reactivity of cyclic ethers of relevance to biofuel combustion
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Biofuels are considered to be an environmental friendly alternative to fossil fuels as they have the potential to reduce the global emissions of greenhouse gases. Studies have showed that an increased use of ethanol could alter the atmospheric chemical composition and enhance urban ozone concentrations resulting in higher human mortality rates. LÄS MER
4. Enzymatic Pretreatment of Lignocellulose Rich Waste for Improved Biogas Production
Master-uppsats, Tema vatten i natur och samhälle; Filosofiska fakultetenSammanfattning : The present study aimed to investigate the methane yield from anaerobic digestion of a lignocellulosic substrate subjected to different pretreatments. The lignocellulosic forest residues materials were milled and then pretreated with the organic solvent NMMO (N-Methylmorpholine N-oxide) and/or the lignolytic enzymes laccase and versatile peroxidase at a dosage of 60 U g-1 total solids (TS) substrate.

5. Preparation of Activated Carbon: Forest residues activated with Phosphoric Acid and Zinc Sulfate
Master-uppsats, KTH/Skolan för kemivetenskap (CHE)Sammanfattning : Activated carbon is a highly adsorbing material and has various scopes of uses depending on needs. It is used in many industries and applications e.g. to clean industrial wastewater, in medicine, discolor sugar and so on. LÄS MER
