17. Internal Tar/CH4 Reforming in Biomass Dual Fluidised Bed Gasifiers towards Fuel Synthesis
Sammanfattning : Production of high-quality syngas from biomass gasification in a dual fluidised bed gasifier (DFBG) has made a significant progress in R&D and Technology demonstration. An S&M scale bio-automotive fuel plant close to the feedstock resources is preferable as biomass feedstock is widely sparse and has relatively low density, low heating value and high moisture content.

18. Origin and composition of the Hällefors composite dyke, central Sweden
Sammanfattning : The Hällefors dyke is a large, wedge-shaped high-level intrusion that trends E-W and has a subvertical dip, the overall dimensions being about 42 km in length and 1 km in width. It was emplaced ca 1550 Ma ago in gneisses of the Svecokarelian (1950-1750 Ma) orogenic belt in south central Sweden. LÄS MER
19. Surface reactions of magnetite and maghemite with dissolved and added ions in process water
Sammanfattning : Reactions between mineral surfaces and dissolved species in process water, both inorganic and organic play an important role in mineral processing. Reverse flotation of finely comminuted iron ore is sometimes employed in order to remove the phosphorous mineral apatite. LÄS MER
20. Impact of Ash on the Properties of Fluidized Bed Materials
Sammanfattning : The utilization of the fluidized bed technology offers the possibility of thermally converting a large variety of biogenic feedstocks. The characteristics of the bed material which is used in the process play a major role regarding the overall process performance. LÄS MER
