1. 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
2. Towards bacterial valorization of low molecular weight lignin
Sammanfattning : Lignin is one of the major constituents in lignocellulosic biomass and is the mostabundant source of renewable aromatics on terrestrial ecosystems. The workcarried out in this thesis concerns bacterial conversion of low molecular weightlignin. LÄS MER
3. Base-catalyzed depolymerization of kraft lignin for valuable chemical production
Sammanfattning : Lignin is one of the three predominant biopolymers that make up plants together with cellulose and hemicellulose, and it is the only plant component that is based on aromatic units. The industrial kraft pulping process generates large amounts of lignin, which is currently used to generate heat for the process. LÄS MER
4. Valorization of low-value lignocellulosic side-streams
Sammanfattning : The development of novel pathways for valorizing low-value streams from pulp, forest, and agricultural industries is crucial for realizing a circular bioeconomy and addressing the needs of both platform chemicals and fuels. Utilizing hemicellulose and lignin as biomass-derived feedstocks facilitates the production of sustainable liquid hydrocarbons, with catalytic hydrodeoxygenation being a key process. LÄS MER
5. Influence of Admixtures on Crystal Nucleation of Vanillin
Sammanfattning : Admixtures like reactants and byproducts are solublenon-crystallizing compounds that can be present in industrialsolutions and affect crystallization of the main substance.This thesis provides experimental and molecular modellingresults on the influence of admixtures on crystal nucleation ofvanillin (VAN).
