  2. 6. Green Aromatics: Catalytic Valorisation of bio-derived 2,5-dimethylfuran over Zeolites and Zeotypes

    Author : Christopher Sauer; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biomass conversion; infrared spectroscopy; BTX Aromatics; 2; 5-dimethylfuran; Zeolite; Catalysis; Online Analysis; Zeotype;

    Abstract : This thesis discusses the use of biomass as a potentially green feedstock for the chemical industry in the urgent shift away from fossil resources. I elaborate on reasons why we cannot afford to burn virgin biomass for energy production, among them a variety of ecosystem services that forests and other lands provide. READ MORE

  5. 8. Anaerobic degradation of phenol and related aromatics

    Author : Anna Karlsson; James M. Tiedje; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aromatic compunds; anaerobic degradation; Fysik; Kemi; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Phenol and other simple aromatic compounds have been found in water leached from landfills, showing that these types of compounds could be either present in disposed waste, or released from it via transformation and degradation processes. Hence, the fate anddegradation potential of such compounds under landfilling conditions is of great concern. READ MORE

  6. 9. Persistent Organic Pollutants and the Environment : A Chemometric Approach to the Study of Halogenated Aromatics

    Author : Tomas Öberg; Bo Bergbäck; Bo Wiman; Jaakko Paasivirta; Högskolan i Kalmar; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Environmental Chemistry; Miljökemi;

    Abstract : Concern is growing about the environmental and health effects of persistent organic pollutants (POPs), many of which are halogenated aromatic compunds. The research reported in this thesis focuses on factors determining their behaviour and release into the environment. READ MORE

  7. 10. Lignocellulosic Ethanol Production: Studies on Sugarcane Bagasse, Paja Brava, Wheat Straw, Quinoa Stalks and Curupaú

    Author : Cristhian Carrasco; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steam pretreatment; ethanol production; SSCF; arabinosylated aromatics; SO2; H2SO4; sugarcane bagasse; paja brava; wheat straw; quinoa stalks; Anadenanthera colubrina;

    Abstract : Lignocellulosic biomass refers to plant material that is composed mainly of cellulose, hemicellulose and lignin. These materials are today of large interest to researchers in the field of biofuel and bioenergy. READ MORE
