  1. 16. Feasibility Study of Production of Bio Methane from Bio Wastes in Sri Lanka and Develop Cost Model for the Production Process

    Magister-uppsats, Högskolan i Gävle/Energisystem

    Författare :Ambagaha Pathirage Thanushka Sandaruwan Peiris; [2016]
    Nyckelord :Renewable Energy; Anaerobic Digestion; Biogas; Biomethane; Cost Model; Investment Decision Tool; Feasibility Study; Sri Lanka;

    Sammanfattning : Generation of wastes as a result of expanding economic activities and change life styles of people is on the increase from recent times in Sri Lanka, especially in urban areas. The government authorities, both national and provincial, have no firm plans to manage the generation of wastes as well as safe disposal of unavoidable wastes. LÄS MER

  2. 17. Utvinning av metan genom membranseparering vid förgasning av biomassa : En litteraturstudie

    M1-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Emil Nilsson; [2015]
    Nyckelord :product gas upgrading; membrane separation; biomethane; glassy polymer; rubbery polymer; gasification biomass; bio-SNG production;

    Sammanfattning : The possibility to extract bio-SNG from the product gas obtained from gasification of biofuel with a pressurized, oxygen-blown CFB gasifier connected to a heat and power station using only membrane separation was theoretically investigated. Selling the methane, instead of feeding it to the plant’s turbine(s), might mean that overall profitability is increased. LÄS MER

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

    Master-uppsats, Linköpings universitet/Tema vatten i natur och samhälleLinköpings universitet/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.

  4. 19. Biomethane to Natural Gas Grid Injection : A Technological Innovation System Analysis

    Master-uppsats, KTH/Energi och klimatstudier, ECS

    Författare :Ankit Singhal; [2012]
    Nyckelord :Biomethane; Natural Gas; Grid Injection; policy; framework; European; biomethane market; Innovation system; Technological Innovation System Analysis;

    Sammanfattning : Biomethane (upgraded form of biogas) holds unlocked potential as a substitute to fossil natural gas, in terms of achieving climate reduction targets as well as developing a locally secured fuel supply. Biomethane is fully compatible with the existing natural gas grid infrastructure. LÄS MER

  5. 20. Biogas Production System as an "Upcycler" : Exergy Analysis and Economic Evaluation

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Aminabbas Parsapour; [2012]
    Nyckelord :biogas; exergy; entropy; economy; brewer s spent grain; BSG; upcycling; sustainability; economic; thermodynamics;

    Sammanfattning : Sustainable development is a growing concern for inhabitants of the planet earth. Consumption of fossil sources keeps up the depletion of nature’s capital and causes environmental impacts. One solution to have a sustainable society is to reduce the dependency on fossil fuels and substitute them by renewable energy sources. LÄS MER
