21. Biochemical conversion of biomass to biofuels : pretreatment–detoxification–hydrolysis–fermentation
Sammanfattning : The use of lignocellulosic materials to replace fossil resources for the industrial production of fuels, chemicals, and materials is increasing. The carbohydrate composition of lignocellulose (i.e. cellulose and hemicellulose) is an abundant source of sugars. LÄS MER
22. Ash transformation in thermochemical conversion of different biomass resources with special focus on phosphorus
Sammanfattning : A great potential exists for increasing the use of bioenergy in thermochemical processes by utilizing agricultural biomass, forest residues, and sewage sludge that have high availability. Many of these biomass assortments have high ash contents with relatively high concentrations of ash-forming elements such as potassium (K), calcium (Ca), silicon (Si), and phosphorus (P). LÄS MER
23. Characteristic Properties and Applications of Fine Particles in Biomass Gasification
Sammanfattning : The gasification of biomass is a promising route to increase the share of renewable sources in the energy mix. Besides having an overall higher thermal efficiency than combustion, it also offers the possibility of producing gaseous and liquid biofuels that can be used in the transport sector. LÄS MER
24. Dioxins and dioxin-like compounds in thermochemical conversion of biomass : formation, distribution and fingerprints
Sammanfattning : In the transition to a sustainable energy supply there is an increasing need to use biomass for replacement of fossil fuel. A key challenge is to utilize biomass conversion technologies in an environmentally sound manner. LÄS MER
25. Quantitative laser diagnostics of gas-phase potassium species in biomass combustion and gasification
Sammanfattning : Thermochemical energy conversion processes, such as combustion and gasification, are applied worldwide for generation of electricity, heat and synthesis of chemicals. Today, these processes are mostly run on non-renewable, fossil fuels and constitute a major source of carbon dioxide emissions. LÄS MER
