1. Hydrothermal Liquefaction of Lignin into Bio-Oil
Sammanfattning : Lignin, one of the three main components of lignocellulosic biomass, is the second most abundant organic polymer found on Earth. Nowadays, most of the lignin (almost 99%) produced in the Kraft pulping process is used as internal fuel. LÄS MER
2. Hydrothermal Liquefaction of Kraft Lignin - The influence of capping agents and residence time
Sammanfattning : In the context of exploring alternatives to replace fossil resources, lignin has been acknowledged as a renewable source of various aromatic compounds that have the potential of being precursors to chemicals as well as fuel additives. Originating from lignocellulosic biomass such as wood, lignin is an amorphous polymer with a high content of aromatic units and, in order to harness these units, it must be depolymerised. LÄS MER
3. Acid-catalyzed Liquefaction of Industrial Side-streams for Producing Wood Adhesives and Particleboard
Sammanfattning : Big quantities of residues and side-streams are generated annually from forest-based and agricultural industries all around the world and present a relatively unexplored renewable resource. Due to the absence of a regularly updated and systematic database of supply, industrial residues and side-streams usually end up in landfill disposal, are used for energy generation, or remain at the production sites.

4. Hydrothermal Depolymerisation of Kraft Lignin: The Influence of Capping Agents and Residence Time
Sammanfattning : Lignin, the aromatic macromolecule found in wood and other lignocellulosic biomass, is envisioned as a future renewable source of aromatic compounds that can be used as, for example, chemicals, fuel additives and resins. A way in which this can be realised is by depolymerising the lignin once it has been isolated from the lignocellulosic biomass. LÄS MER
5. Evaluating Swedish seaweeds for biorefinery
Sammanfattning : A sustainable future demands a transition from oil to biomass to produce fuels, chemicals, commodities, and energy. However, to generate the predicted amount of bioenergy required by 2050, all the biomass harvested today should be utilized. One type of biomass that has received relatively little attention is seaweeds. LÄS MER
