1. Ethanol from lignocellulose : Management of by-products of hydrolysis
Sammanfattning : Fuel ethanol can be produced from lignocellulosic materials, such as residues from agriculture and forestry. The polysaccharides of lignocellulose are converted to sugars by hydrolysis and the sugars can then be fermented to ethanol using microorganisms. However, during hydrolysis a wide range of by-products are also generated. LÄS MER
2. Ethanol from lignocellulose : physiological effects of inhibitors and fermentation strategies
Sammanfattning : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). LÄS MER
3. Fast Dynamic Processes in Solution Studied by NMR Spectroscopy
Sammanfattning : Nuclear magnetic resonance (NMR) spectroscopy is capable to deliver a detailed information about the dynamics on molecular level in a wide range of time scales, especially if accompanied by suitably chosen theoretical tools. In this work, we employed a set of high-resolution NMR techniques to investigate dynamics processes in several weakly interacting molecular systems in solution. LÄS MER
4. Ethanol Pulping of Reed Canary Grass
Sammanfattning : The aim of this study was to investigate the possibility of processing an agricultural crop grown in Sweden to usable pulp. A further purpose was to study ethanol pulping applied to a non-wood raw material.The first part of this thesis deals with the criteria for selecting a fibre crop for further studies. LÄS MER
