  1. 1. Integration of filamentous fungi in ethanol dry-mill biorefinery

    University dissertation from Borås : Högskolan i Borås

    Author : Jorge Ferreira; Högskolan i Borås.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airlift bioreactors; ascomycetes; biomass; bubble column; ethanol; feed; Neurospora intermedia; thin stillage; zygomycetes; Resource Recovery; Resursåtervinning;

    Abstract : The industrial production of bioethanol as a replacement to gasoline is well-established worldwide, using starch- or sugar-rich substrates. Additionally, the bioethanol plants produce animal feeds derived from fermentation leftovers. The biorefinery character of bioethanol plants can be enhanced via process diversification. READ MORE

  2. 2. Conversion processes for biofuel production

    University dissertation from Borås : Högskolan i Borås

    Author : Jerry Luis Solis; Yohannes Kiros; Mohammad Taherzadeh; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Second-generation biofuels; biodiesel; heterogeneous catalysts; non-edible oils; ethanol; residual biomass; native yeast strains.; Andra generationens biobränslen; biodiesel; heterogena katalysatorer; oätliga oljor; etanol; rester av biomassa; naturliga jäststammar; Chemical Engineering; Kemiteknik; Energiteknik; Energy Technology;

    Abstract : Despite the global positive impacts of soybean-, maize- and sugarcane-based (first-generation) liquid biofuels, several drawbacks pertaining to increased use of agricultural land, causing deforestation in some countries and extensive practice of fertilizers have been observed. As a result, developing advanced (second- and third-generation) liquid biofuels have been identified as better alternatives and are considered to be of great importance in the future. READ MORE

  3. 3. Decentralised energy systems based on biomass

    University dissertation from Borås : Högskolan i Borås

    Author : Marie Kimming; Sveriges lantbruksuniversitet.; [2015]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Replacing fossil fuels with renewable energy sources is recognised as an important measure to mitigate climate change. Residual biomass from agriculture and forestry and short-rotation coppice grown on unused land can be converted to heat, power and fuel without directly compromising production of edible crops.

  4. 4. Forest biomass terminal properties and activities

    University dissertation from Borås : Högskolan i Borås

    Author : Kalvis Kons; Sveriges lantbruksuniversitet.; [2015]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Primary residual forest biomass is an important source of energy in Sweden. The fuel quality of this biomass depends on several factors including its moisture content, ash content, and particle size distribution. READ MORE

  5. 5. Towards Understanding the Pelletizing Process of Biomass Perspectives on Energy Efficiency and Pelletability of Pure Substances

    University dissertation from Karlstad : Karlstads universitet

    Author : Stefan Frodeson; Karlstads universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pelletability; wood pellets; densification; chemical composition; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : The use of fossil resources has to decrease and the use of renewable resources has to increase significantly to mitigate the climate change. In this change towards more renewable resources, biomasses will play an important role, both for energy use and for products. READ MORE
