  4. 2. Ethanol from lignocellulose : Management of by-products of hydrolysis

    Author : Björn Alriksson; J Leif Jönsson; Vincent Eijsink; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ethanol; Lignocellulose; Detoxification; Genetic engineering; Enzyme production; Biochemistry; Biokemi; Kemi; Chemistry;

    Abstract : Fuel ethanol can be produced from lignocellulosic materials, such as residues from agriculture and forestry. The polysaccharides of lignocellulose are converted to sugars by hydrolysis and the sugars can then be fermented to ethanol using microorganisms. However, during hydrolysis a wide range of by-products are also generated. READ MORE

  5. 3. State Estimation for Distributed and Hybrid Systems

    Author : Peter Alriksson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Joint Maximum a Posteriori Estimation; Sensor Networks; Distributed State Estimation; Networked Embedded Systems; Markov Jump Linear Systems; Sensor Scheduling;

    Abstract : This thesis deals with two aspects of recursive state estimation: distributed estimation and estimation for hybrid systems. In the first part, an approximate distributed Kalman filter is developed. Nodes update their state estimates by linearly combining local measurements and estimates from their neighbors. READ MORE

  6. 4. Environmental preferences among steel stakeholders

    Author : Stina Alriksson; Marianne Henningsson; Carl-Erik Grip; Anders Roos; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conjoint analysis; environmental communication; focus group; light weighting; PLS; preferences; Q-methodology; risk perception; steel; stakeholders; Miljövetenskap; Environmental Science;

    Abstract : Emissions of carbon dioxide, dioxins, nitrogen oxides and particulate matter as well as use of non-renewable resources and energy are some important sustainability challenges for the Swedish steel industry. Much effort has been made, mainly by technical solutions, which to a high degree have decreased the emissions during the last 30 years. READ MORE

  7. 5. Ethanol from lignocellulose : Alkali detoxification of dilute-acid spruce hydrolysates

    Author : Björn Alriksson; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Kemi; Chemistry;

    Abstract : Detoxification of dilute-acid lignocellulose hydrolysates by treatment with Ca(OH)2 (overliming) efficiently improves the production of fuel ethanol, but is associated with drawbacks like sugar degradation and CaSO4 precipitation. In factorial designed experiments, in which pH and temperature were varied, dilute-acid spruce hydrolysates were treated with Ca(OH)2, NH4OH or NaOH. READ MORE
