  2. 1. Sampling and Analysis of Tars by Means of Photo Ionization Detection and Solid Phase Micro Extraction

    Author : Mozhgan Ahmadi Svensson; Klas Engvall; Wiebren de Jong; KTH; []
    Keywords : ;

    Abstract : Gasification of biomass will likely play an important role in the production of energy and chemicals in a future sustainable society. However, during gasification impurities, such as tars, will be formed. Tars may cause fouling and blockages of equipment downstream the gasifier. READ MORE

    Abstract : The International Agency for Research on Cancer (IARC) stated that chromium in the form of Cr(VI) has been deemed to be a class-A human carcinogen. It has been a major contaminant associated with wastewater. READ MORE

  6. 4. Gasification of biochars: Evolution of pore structure, effects of alkalis and alkali release

    Author : Saiman Ding; Klas Engvall; Efthymios Kantarelis; Jukka Konttinen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; alkali release; kinetic modelling; char reactivity; pore structure; alkalis effects; förgasning; frigörande av alkalier; kinetisk modellering; kolreaktivitet; porstruktur; alkalieffekter; Chemical Engineering; Kemiteknik;

    Abstract : Renewable energy sources are indispensable to meet the rising demand of energy usage  while  reducing  the  negative  environmental  impact  of utilising fossil  fuels. Gasification  is  an  efficient  technology  to  convert  biogenic waste  into  valuable gaseous products. READ MORE

  7. 5. Removal of Natural Organic Matter to reduce the presence of Trihalomethanes in drinking water

    Author : Indiana Garcia; Luis Moreno; Bhekie B. Mamba; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi;

    Abstract : In countries located in tropical zones, a critical task in drinking water plants is the removal of the natural organic matter (NOM), particularly during the rainy season when a lot of organic matter is transported by run-off into the water bodies. It provokes overloaded in the plants and they have often needed to be shut down. READ MORE
