  1. 1. Lignocellulosic Ethanol Production: Studies on Sugarcane Bagasse, Paja Brava, Wheat Straw, Quinoa Stalks and Curupaú

    Författare :Cristhian Carrasco; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steam pretreatment; ethanol production; SSCF; arabinosylated aromatics; SO2; H2SO4; sugarcane bagasse; paja brava; wheat straw; quinoa stalks; Anadenanthera colubrina;

    Sammanfattning : Lignocellulosic biomass refers to plant material that is composed mainly of cellulose, hemicellulose and lignin. These materials are today of large interest to researchers in the field of biofuel and bioenergy. LÄS MER

  3. 2. Bioethanol Production from Lignocellulosic Materials: Some studies on Sugarcane Bagasse and Paja Brava

    Författare :Cristhian Carrasco; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paja Brava Sugarcane Bagasse Saccharomyces cerevisiae Pichia stipitis;

    Sammanfattning : The commercial feasibility of ethanol production from biomass is dependent on the availability of lignocellulose in large amounts at low cost. Various kinds of agricultural residues are of interest, due to the fact that these feedstocks have well-established cultivation procedures already in place, as well as technology for harvest and transportation.

  4. 3. Development of the Steam Pretreatment Process for Production of Ethanol from Lignocellulosic Biomass

    Författare :Sanam Monavari; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spruce; Ethanol production; Sugarcane bagasse; SSF; Fermentation; Enzymatic hydrolysis; SO2; Steam pretreatment; Acid catalyst;

    Sammanfattning : At a time when natural petroleum resources are on the verge of depletion, and concern about climate change is increasing, the potential of lignocellulosic material for the production of bioethanol is well recognized. Ethanol can be produced from biomass through enzymatic hydrolysis and fermentation. LÄS MER

  5. 4. Study on the structure and properties of xylan extracted from eucalyptus, sugarcane bagasse and sugarcane straw

    Författare :Danila Carvalho; Mikael Lindström; Åsa Emmer; Sverker Danielsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Lignocellulosic biomasses are an important source of chemical components such as cellulose, lignin and hemicelluloses, and can be used for a variety of purposes in both the pulp and paper and chemical conversion industries. Xylan, the main hemicellulose found in hardwood and grass plants, plays an important role during the pulping/pretreatment process reactions, including those used in 2nd generation bioethanol production.

  7. 5. Land and climate effects of bioenergy - Brazilian sugarcane ethanol and combined biofuel-district heating in Europe

    Författare :Andrea Egeskog; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sugarcane ethanol; bioenergy; Brazil; biofuels for transport; EU; district heating;

    Sammanfattning : According to the Intergovernmental Panel on Climate Change, use of fossil fuels is the largest source ofthe increase in atmospheric CO2. The second largest is land use change. To reach stringent climate targets,emissions from fossil fuel combustion and land use change will need to be reduced to near zerowithin a few decades. LÄS MER
