  1. 1. Pre-treatment of straw and forest residue for biogas production; Recycling and Reuse of NMMO

    Master-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Shahram Zareibezini; Ravi Sankar Reddy Yaparla; [2014]
    Nyckelord :NMMO pretreatment; biogas production; anaerobic digestion; barley straw; forest residues; NMMO recycling and reuse;

    Sammanfattning : N-methylmorpholine-N-oxide has shown a positive effect for the pretreatmentof lignocelluloses. Pretreatment by NMMO was developed to enhance thedigestibility of lignocellulosic biomass.Barely straw and forest residue were pretreated by N-methylmorpholine-Noxide(NMMO) prior to anaerobic digestion.

  3. 2. Enzymatic Pretreatment of Lignocellulose Rich Waste for Improved Biogas Production

    Master-uppsats, Tema vatten i natur och samhälle; Filosofiska fakulteten

    Författare :Carin Kvillborn; [2013]
    Nyckelord :Biogas; anaerobic digestion; lignin; laccase; versatile peroxidase; NMMO; Biogas; anaerob nedbrytning; lignin; laccase; versatile peroxidas; NMMO;

    Sammanfattning : The present study aimed to investigate the methane yield from anaerobic digestion of a lignocellulosic substrate subjected to different pretreatments. The lignocellulosic forest residues materials were milled and then pretreated with the organic solvent NMMO (N-Methylmorpholine N-oxide) and/or the lignolytic enzymes laccase and versatile peroxidase at a dosage of 60 U g-1 total solids (TS) substrate.

    Sammanfattning : Modern society depends on fossil fuels to fulfill the increasing energy demand, which could cause further damages in the environment. Therefore, it is mandatory to develop technologies for the production of efficient alternative renewable energy sources, like biofuels. LÄS MER

  5. 4. High rate biogas production from waste textiles

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Karthik Rajendran; Gopinath Balasubramanian; [2011]
    Nyckelord :biogas; waste textiles; nmmo-pretreatment; two-stage anaerobic digestion; UASB; CSTR;

    Sammanfattning : Textile is a global product used by all people in the world. These textiles after the use are thrown into the trash for incineration or land filling. However an efficient way that can be used to produce more energy, in an environmentally friendly process is anaerobic digestion. Waste textiles which contain cellulosic fibers (e. LÄS MER
