  1. 21. Filtration of Cellulosic material - the impact of ionic strength and electric field

    Author : Anna Lidén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electro-assisted; microfibrillated cellulose; ionic strength; microcrystalline cellulose; dead-end filtration;

    Abstract : It is crucial that dewatering technology is considered if an economically feasible production of cellulosic materials is to be achieved. Cellulosic materials are often produced in dilute streams and therefore require great amounts of water to be removed to allow for reasonable transportation costs and/or further modifications.

  2. 22. Influence of peat addition to biomass pellets on combustion characteristics in residential appliances

    Author : Ida-Linn Näzelius; Markus Broström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : The biomass pellet consumption, both in the industry and in residential appliances, has increased during the latest years and this is expected to continue. In order to handle the demand, more ash rich (>0,5 wt-%) raw materials have been introduced as energy wood and other forest based fuels. READ MORE

  3. 23. Studies on preparation and properties of nanophase metal oxides

    Author : Tarja Turkki; KTH; []
    Keywords : ;

    Abstract : This thesis is about science on an atomic scale - aninterdisciplinary approach to nanoparticles. Studies of thepreparation of nanoparticles using both physical and chemicalmethods are presented. Understanding and controlling factorsfor particle growth during synthesis are the keys to successfulfabrication of materials with tailored properties. READ MORE

  4. 24. Optical Diagnostics for Quantitative Potassium Chemistry in Biomass Thermochemical Conversion Processes

    Author : Wubin Weng; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical diagnostics; Quantitative measurement; TDLAS; Sulfation; Biomass; UV absorption spectroscopy; TLAF; Potassium chemistry;

    Abstract : Biomass is an essential sustainable and carbon-neutral energy source. Through thermochemical conversion processes, such as combustion and gasification, biomass can generally be used in boilers to provide heat and/or power. Biomass fuels contain varying amounts of potassium, chlorine and sulfur. READ MORE

  5. 25. Process water geochemistry at the Kiirunavaara iron mine, northern Sweden

    Author : Magnus Westerstrand; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : Understanding process water characteristics and variations is important for ensuring the quality of mineral processing of iron ore. Large amounts of water are used, and the quality of the water can be crucial for processes such as flotation, agglomeration and balling. READ MORE
