1. Improved Energy Efficiency and Fuel Substitution in the Iron and Steel Industry
Sammanfattning : IPCC reported in its climate change report 2013 that the atmospheric concentrations of the greenhouse gases (GHG) carbon dioxide (CO2), methane, and nitrous oxide now have reached the highest levels in the past 800,000 years. CO2 concentration has increased by 40% since pre-industrial times and the primary source is fossil fuel combustion. LÄS MER
2. Bio-refinery system integrated with pulp and paper mills using black liquor gasification
Sammanfattning : Mitigation of climate change and energy security are major driving forces for increased biomass energy utilization. The pulp and paper industry consumes a large proportion of biomass worldwide that include bark, wood residues, and black liquor. LÄS MER
3. Analysing performance of bio-refinery systems by integrating black liquor gasification with chemical pulp mills
Sammanfattning : Mitigation of climate change and energy security are major driving forces for increased biomass utilization. The pulp and paper industry consumes a large proportion of the biomass worldwide including bark, wood residues, and black liquor. LÄS MER
4. Fighting flameless fires : Initiating and extinguishing self-sustainedsmoldering fires in wood pellets
Sammanfattning : Smoldering fires represent domestic, environmental and industrial hazards. This flameless form of combustion is more easily initiated than flaming, and is also more persistent and difficult to extinguish. The growing demand for non-fossil fuels has increased the use of solid biofuels such as biomass. LÄS MER
5. The effect of wood properties on oxidative isolation of cellulose nanofibrils and characterization of networks
Sammanfattning : Wood is a natural resource that has been an integral part of society for as long as humans have been on Earth. From serving as fuel for fire and construction material the applications of wood has been developed in modern times and only surged as a consequence of societal strive for sustainability and usage of green resources.
