    University dissertation from Umeå : Umeå University

    Author : Zhao Wang; Leif Jönsson; Brett Pletschke; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recalcitrance; Pretreatment; Enzymatic saccharification; Ionic liquid; Steam explosion; Enzyme inhibition; Non-productive binding; Microbial inhibitors;

    Abstract : Lignocellulose is an inexpensive and abundant renewable resource that can be used to produce advanced biofuels, green chemicals, and other bio-based products. Pretreatment and efficient enzymatic saccharification are essential features of bioconversion of lignocellulosic biomass. READ MORE

  2. 2. Waste Textiles Bioprocessing to Ethanol and Biogas

    University dissertation from Umeå : Umeå University

    Author : Azam Jeihanipour; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzymatic hydrolysis; cotton-based cellulose; recycling; biorefinery; biogas; pretreatment; bioethanol; cellulose recalcitrance; waste textile.;

    Abstract : In the world today, the need for sustainable processes is increasing. The work of the present thesis has been focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. READ MORE

  4. 4. Pretreatment of cellulosic waste and high rate biogas production

    University dissertation from University of Borås, School of Engineering

    Author : Solmaz Aslanzadeh; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Two-stage anaerobic digestion; N-methylmorpholine N-oxide NMMO pretreatment; Lignocelluloses; Textile waste; Biofuels; Resursåtervinning; Resource Recovery;

    Abstract : The application of anaerobic digestion technology is growing worldwide, mainly because of its environmental benefits. Nevertheless, anaerobic degradation is a rather slow and sensitive process. One of the reasons is the recalcitrance nature of certain fractions of the substrate (e.g. READ MORE

  5. 5. Biochemical conversion of biomass to biofuels pretreatment–detoxification–hydrolysis–fermentation

    University dissertation from Umeå : Umeå universitet

    Author : Venkata Prabhakar Soudham; Jyri-Pekka Mikkola; Christer Larsson; Tom Birger Granström; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulosic materials; Ionic liquids; Pretreatment; Inhibitors; Detoxification; Ferrous sulfate and hydrogen peroxide; reducing agents; alkaline treatments; Hydrolysis; Fermentation; Biofuels; biokemi; Biochemistry;

    Abstract : The use of lignocellulosic materials to replace fossil resources for the industrial production of fuels, chemicals, and materials is increasing. The carbohydrate composition of lignocellulose (i.e. cellulose and hemicellulose) is an abundant source of sugars. READ MORE
