  1. 1. Study of the activity of catalysts for the production of high quality biomass gasification gas with emphasis on Ni-substituted Ba-hexaaluminates

    University dissertation from Linnaeus University

    Author : Charlotte Parsland; Linnéuniversitetet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioenergy; catalysis; tars; steam reforming; gasification; hexaaluminate; bioenergi; katalys; tjäror; ångreformering; förgasning; hexaaluminat; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology; Kemi; Chemistry;

    Abstract : The fossil hydrocarbons are not inexhaustible, and their use is not without impact in our need of energy, fuels and hydrocarbons as building blocks for organic materials. The quest for renewable, environmentally more friendly technologies are in need and woody biomass is a promising candidate, well provided in the boreal parts of the world. READ MORE

    Abstract : The pulp and paper industry is a large producer of wastewater and sludge, putting high pressure on waste treatment. In addition, more rigorous environmental legislation for pollution control and demands to increase the use of renewable energy have put further pressure on the pulp and paper industry’s waste treatment, where anaerobic digestion (AD) and the production of methane could pose a solution.

    Abstract : The production of biofuels has increased in recent years, to reduce the dependence on fossil fuels and mitigate climate change. However, current production practices are heavily criticized on their environmental sustainability. READ MORE

  4. 4. Char conversion kinetics and aerosol characterization in biomass gasification

    University dissertation from Växjö : Linnaeus University Press

    Author : Leteng Lin; Linnéuniversitetet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass gasification; fluidized bed; char; kinetics; aerosol; APS; TEOM; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Abstract : Biomass gasification is a thermochemical conversion by partial oxidation at elevated temperature of solid biomass into a gaseous energy carrier. The product gas contains the major components CO, H2, CO2, CH4, as well as some tar and inorganic impurities and solid particles such as ash, bed material, soot and char. READ MORE

  5. 5. European bioenergy markets

    University dissertation from Växjö : Linnaeus University Press

    Author : Olle Olsson; Sveriges lantbruksuniversitet.; [2009]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Energy market integration is beneficial in several ways: it can increase competition, reduce the risk of local shortages or oversupply and can also reduce price volatility. As demand for renewable energy is growing, bioenergy from solid biomass fuels is changing from its traditional role as a locally utilized form of energy into an internationally traded energy commodity.
