1. Char conversion kinetics and aerosol characterization in biomass gasification
Sammanfattning : Biomass gasification is a thermochemical conversion by partial oxidation at elevated temperature of solid biomass into a gaseous energy carrier. The product gas contains the major components CO, H2, CO2, CH4, as well as some tar and inorganic impurities and solid particles such as ash, bed material, soot and char. LÄS MER
2. Climate impact of the sustainable use of forest biomass in energy and material system : a life cycle perspective
Sammanfattning : Human society releases greenhouse gas emissions to the atmosphere while providing housing, heat, mobility and industrial production. Man-made greenhouse gas emissions are the main causes of climate change, coming mainly from burning fossil fuels and land-use changes. LÄS MER
3. Benzene-char conversion and particle-vapor characterization in biomass gasification
Sammanfattning : Biomass is increasingly attracting attention as an alternative to fossil fuels. Gasification permits the thermochemical conversion of biomass into a product gas rich in carbon monoxide and hydrogen. The product gas can be further processed to generate heat, electricity, synthesis gas, chemicals, and biofuels. LÄS MER
4. Study of the activity of catalysts for the production of high quality biomass gasification gas : with emphasis on Ni-substituted Ba-hexaaluminates
Sammanfattning : The fossil hydrocarbons are not inexhaustible, and their use is not without impact in our need of energy, fuels and hydrocarbons as building blocks for organic materials. The quest for renewable, environmentally more friendly technologies are in need and woody biomass is a promising candidate, well provided in the boreal parts of the world. LÄS MER
5. Characterization of conversion zones in a reciprocating grate furnace firing wet woody biomass
Sammanfattning : Grate-firing systems are a common and popular combustion technology for burning biomass. However, combustion of biomass in these furnaces may emit a large amount of pollutants in the form of CO, CH4, PAH, NOx, and particles. LÄS MER
