  2. 1. Lime Mud Reburning. Properties and Quality of the Lime Produced

    Author : Charlotta Hanson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : It is of utmost importance that the white liquor used in the digester of a sulphate pulp mill is of high quality. The white liquor is prepared in the causticizing plant, through causticizing of the sodium carbonate in the green liquor. READ MORE

  4. 2. Water content measurement in woody biomass : using dielectric constant at radio frequencies

    Author : Ana Marta Marques Duarte da Paz; Erik Dahquist; Pertti Vainikainen; Mälardalens högskola; []
    Keywords : Energi- och miljöteknik;

    Abstract : The will for replacement of fossil fuels increased the use of woody biomass as fuel in heating and power plants. An important parameter for the use woody biomass as fuel is the water content of biomass as it influences the heating value and thereby the combustion control and pricing. READ MORE

    Abstract : This doctoral thesis consists of a literature review, presented in two papers, and another six papers describing experimental studies of the influence of different kinds of wax and polyphosporic acid on bitumen and asphalt concrete mixture properties. The literature review should give an extensive description of the field of knowledge concerning wax in bitumen. READ MORE

  6. 4. Isotopic analyses of biological materials by single and multi-collector sector field ICP-MS

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

    Abstract : Investigations concerning naturally occurring, mass dependent isotope fractionation of transition elements in biological materials have only been carried out during a very short period of time. Due to the lack of detailed descriptions of the analytical performance in previously reported work, the major focus of this study has therefore been to evaluate aspects of sample preparation and detection for obtaining precise and accurate isotopic ratios by multi-collector inductively coupled plasma mass spectrometry (MC- ICP-MS) using high mass-resolution.
