1. Transport of Particles in Turbulent Flow with Application to Bio-Fuels
Sammanfattning : Development of civilization faces a challenge of developing the resources of energy demand for the modern life. Extensive use of conventional fuel resources like crude oil and coal rise up a serious problem of increasing CO2 emission. New records levels of CO2 were registered during the early beginning of industrial revolution (http://climate.nasa. LÄS MER
2. Measuring Elemental Carbon in Occupational Environments
Sammanfattning : Carbonaceous aerosol particles from combustion, such as diesel exhaust particles (DEP), harm human health and affect the Earth’s radiative system.Elemental carbon (EC) has been proposed to be used as a marker of DEP. LÄS MER
3. 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
4. Catalytic Steam Pyrolysis of Biomass for Production of Liquid Feedstock
Sammanfattning : The current societal needs for fuels and chemical commodities strongly depend on fossil resources. This dependence can lead to economic instabilities, political problems and insecurity of supplies. LÄS MER
5. 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
