11. Kraft lignin valorization by hydrotreatment over Mo-based sulfided catalysts
Sammanfattning : The production of green fuels and chemicals from bio-based feedstock can suppress the dependency on fossil resources and help mitigate global climate challenges. Kraft lignin is a thermochemically modified natural lignin obtained from the pulping process as a byproduct. LÄS MER
12. 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
13. Pressure and Solidosity Profiles in Cake Filtration
Sammanfattning : Filtration is an important unit operation in theseparation of liquids from solids. The aim of this work was toinvestigate filtration properties of lignin sludge obtained in theproduction of fuel ethanol from spruce wood. LÄS MER
14. Fast pyrolysis of biomass : primary products and reaction pathways
Sammanfattning : Pyrolysis of biomass to produce liquid fuel and chemicals has been considered as an alternativeto fossil fuel because biomass has a lower environmental impact; moreover, it is renewable andcould be sustainable. However, the process of bio-oil production involves a series of complexchemical reactions which are dependent on the biomass feedstock and composition,temperature, heating rate as well as residence time.

15. Understanding and improving microbial cell factories through Large Scale Data-approaches
Sammanfattning : Since the advent of high-throughput genome sequencing methods in the mid-2000s, molecular biology has rapidly transitioned towards data-intensive science. Recent technological developments have increased the accessibility of omics experiments by decreasing the cost, while the concurrent design of new algorithms have improved the computational work-flow needed to analyse the large datasets generated.
