1. Fuel Ethanol Production from Corn Stover: Optimization of Steam Pretreatment and Improvement of Simultaneous Saccharification and Fermentation
Sammanfattning : Fuel ethanol, produced from biomass, could well be tomorrow's replacement for gasoline. This thesis deals with the production of fuel ethanol from corn stover using an enzymatic process consisting of the following main steps: steam pretreatment of the raw material, enzymatic hydrolysis, fermentation of the sugars and ethanol refining.

2. From recovery boiler to integration of a textile fiber plant : Combination of mass balance analysis and chemical engineering
Sammanfattning : Modern chemical technology is an efficient tool for solving problems, particularly within the complex environment of the pulp and paper industry, and the combination of experimental studies, mill data and mass balance calculations are of fundamental importance to the development of the industry. In this study various examples are presented, whereby chemical technology is of fundamental importance. LÄS MER
3. Self Assembly of Hardwood Xylan -In Aqueous Solution and at Cellulosic Surfaces
Sammanfattning : The climate change on our planet is an issue of great concern. The dignity of this issue was confirmed by the award of the international panel of climate change (IPCC) the Nobel peace prize. This problem arises from the way that we live our lives, how we produce energy, materials and chemicals from a fossil source. LÄS MER
4. Production of Ethanol from Spruce at High Solids Concentrations - An Experimental Study on Process Development of Simultaneous Saccharification and Fermentation
Sammanfattning : Replacing fossil fuels by biofuels such as ethanol is considered a promising alternative to reduce greenhouse gas (GHG) emissions and mitigate climate change. Biofuels produced from lignocellulosic biomass, so-called second generation biofuels, result in decreased GHG emissions and limit competition with food and animal feed production. LÄS MER
5. Process Development of Bioethanol Production from Wheat and Barley Residues Steam Pretreatment and SSF
Sammanfattning : Bioethanol has received increasing attention as an alternative to petrol due to the current dependency on supplies from other countries and due to the increased concentration of the greenhouse gas carbon dioxide in the atmosphere. In this thesis, the development of 2nd generation production processes for bioethanol production from the lignocellulosic part of biomass is discussed. LÄS MER
