1. Enhanced Methane and Hydrogen production in Reverse Membrane Bioreactors via Syngas Fermentation
Sammanfattning : of waste treatment processes, such as the anaerobic digestion. This biochemical process converts organic substrates into biogas, with anaerobic microorganisms. However, some types of substrates have low bio-degradability due to its recalcitrance or the presence of inhibitors. LÄS MER
2. GASIFICATION-BASED BIOREFINERY FOR MECHANICAL PULP MILLS
Sammanfattning : The modern concept of "biorefinery" is dominantly based on chemical pulp mills to create more value than cellulose pulp fibres, and energy from the dissolved lignins and hemicelluloses. This concept is characterized by the conversion of biomass into various biobased products. LÄS MER
3. Opportunities to broaden biomass feedstocks in thermochemical conversion technologies
Sammanfattning : Global environmental concerns are motivating a growing interest in broadening the biomass feedstock base in several energy sectors, including (i) the domestic heating sector, presently dominated by stem wood combustion, and (ii) biofuel production, presently dominated by edible crops. The objective of this thesis is to investigate new opportunities to broaden the biomass feedstock in thermochemical conversion technologies. LÄS MER
4. Generation of synthesis gas for fuels and chemicals production
Sammanfattning : Many scientists believe that the oil production will peak in the near future, if the peak has not already occurred. Peak oil theories and uncertain future oil deliveries have stimulated interest in alternative sources of fuel and chemicals. LÄS MER
