  1. 1. Online fibre property measurements : foundations for a method based on ultrasound attenuation

    Author : Yvonne Aitomäki; Richard Challis; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : This thesis presents the foundations of a method for estimating fibre properties of pulp suitable for online application in the pulp and paper industry. In the pulp and paper industry, increased efficiency and greater paper quality control are two of the industry's main objectives. READ MORE

  2. 2. Alkali Metals and Tar in Biomass Thermochemical Conversion: Development and Application of Online Measurement Techniques

    Author : Dan Gall; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tar; Alkali Metals; Biomass; Thermochemical conversion; Online Measurements.;

    Abstract : Biomass is a renewable resource that can substitute the fossil-based products we depend on today. However, the conversion techniques require further improvement in order to be competitive with the traditional industry. READ MORE

  3. 3. Alkali Release and Effects on Biomass Thermal Conversion Processes

    Author : Yaxin Ge; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Co-conversion; Alkali; Biomass; bed material; thermal conversion; online measurements;

    Abstract : High alkali content is an important feature of biomass, and it has a series of implications for thermal conversion processes. This thesis focuses on the release of alkali during various biomass thermal conversion processes, including biomass pyrolysis, char gasification, co-conversion of different types of biomass, and thermal conversion of biomass mixed with fresh and used bed materials.
