  2. 1. 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.

    Abstract : "Becoming Muslim: Meanings of Conversion to Islam" is an ethnographic study analyzing the identity-making of female Muslim converts. It is based on eighteen in-depth interviews with six women in Sweden and three women in the U.S. READ MORE

  6. 4. Catalytic conversion of LignoBoost Kraft lignin into liquid products in near-critical water

    Author : Huyen Nguyen Lyckeskog; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LignoBoost; Catalytic conversion; Hydrothermal conversion; Bio-oil; Near-critical water; Lignin;

    Abstract : Lignin, one of the three main components of lignocellulosic biomass, is the second most abundant organic polymer found on Earth. Due to its aromatic nature, lignin is recognized as being a potential feedstock for producing transportation fuel and high value-added chemicals. READ MORE

  7. 5. Wave Energy Conversion : Linear Synchronous Permanent Magnet Generator

    Author : Oskar Danielsson; Mats Leijon; Göran Engdahl; Uppsala universitet; []
    Keywords : Engineering physics; Finite element method; linear synchronous generator; longitudinal end effect; permanent magnet; point absorber; offshore testing; wave power; Teknisk fysik;

    Abstract : This thesis studies the electric aspects of a linear synchronous permanent magnet generator. The generator is designed for use in a wave energy converter, which determines the fundamental requirements of the generator. The electromagnetic properties of the generator are investigated with a finite element based simulation tool. READ MORE
