1. 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

3. 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
4. Palladium-catalyzed lignin valorization : Towards a lignin-based biorefinery
Sammanfattning : The work described in this thesis focuses on the cleavage of the β-O-4′ bond, which is the most abundant interunit linkage in the lignin polymer.In the first part, three methods based on palladium catalysis have been developed and their applicability has been verified using lignin model compounds.

5. Production and transformation of organic compounds from renewable feedstock : Catalytic approaches
Sammanfattning : This thesis is focused on the development of strategies for lignocellulosic biomass valorization. The thesis consists of two parts.The first part of the presented work is related to the catalytic fractionation of biomass (lignin-first approach) and the production of monomeric compounds from lignocellulose.
