    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

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

    Abstract : 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.

    Keywords : Biogas; anaerobic digestion; lignin; laccase; versatile peroxidase; NMMO; Biogas; anaerob nedbrytning; lignin; laccase; versatile peroxidas; NMMO;

    Abstract : 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.

    Abstract : 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. READ MORE

  5. 4. High rate biogas production from waste textiles

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

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

    Abstract : 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. READ MORE
