  1. 1. Developments in Feedstock Analysis and Process Control for Biogas Production

    Författare :Sten Strömberg; Lunds universitet.; Lund University.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; Process control; Biochemical Methane Potential; Process analysis; Feedstock; Biogas;

    Sammanfattning : Popular Abstract in Swedish Med snabbare och pålitligare analysresultat finns stora möjligheter till ett ökat utnyttjande av avfallsresurser för produktion av förnybar energi. Resultat från min forskning gör det möjligt att analysera råvaror för biogasproduktion med större säkerhet och med möjligheten att få upp till nio gånger snabbare resultat. LÄS MER

  2. 2. Anaerobic digestion of horse manure renewable energy and plant nutrients in a systems perspective

    Detta är en avhandling från Gävle : Gävle University Press

    Författare :Åsa Hadin; Högskolan i Gävle.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Horse manure; horse keeping; anaerobic digestion; nutrient recycling; systems perspective; bedding; methane potential; feedstock; biogas; biofertilizer; Hästgödsel; hästhållning; rötning; näringsåterföring; systemperspektiv; strömaterial; metanpotential; biogassubstrat; biogas; biogödsel;

    Sammanfattning : In horse keeping horse manure is produced, which can be utilized as a fertilizer or considered a waste. Horse manure constitutes a resource in terms of both plant nutrients and energy. In addition energy policies and objectives aim at replacing fossil fuels with renewable energy sources. LÄS MER

  3. 3. Biomass to Biofuel : Syngas Cleaning and Biomass Feedstock

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Ramiar Sadegh-Vaziri; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas-Solid Reaction; ZnO Sul_dation; Outward Growth; Hollow Particles; Algae Flocculation; PBEs; Fractal Clusters; Restructuring of Clusters; Deposition of Clusters; Primary Particle Aggregation.;

    Sammanfattning : This thesis builds around the idea of a biofuel production process that is comprised of biomass production, biomass gasification, gas cleaning, and fuel production. In this work, we specifically looked into H2S removal as a part of cleaning the producer gas and flocculation of microalgae which is involved in the harvesting of microalgae after biomass production.

  4. 4. Recalcitrance of wood to biochemical conversion : feedstock properties, pretreatment, saccharification, and fermentability

    Detta är en avhandling från Umeå : Umeå University

    Författare :Zhao Wang; Umeå universitet.; [2018]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 5. From waste problem to renewable energy resource exploring horse manure as feedstock for anaerobic digestion

    Detta är en avhandling från Gävle : Gävle University Press

    Författare :Åsa Hadin; Högskolan i Gävle.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; horse manure; environmental systems analysis; energy systems; renewable energy; environmental impact; anaerobic digestion; biogas; biofertilizer; systems perspective; bedding; incineration; composting; horse manure utilization;

    Sammanfattning : A sustainable energy system requires, according to energy policies, reduced emissions of greenhouse gases, increased ratio of renewable sources of energy and more efficient use of energy. Horse manure could be regarded as waste, but also as a resource for renewable energy and plant nutrients. LÄS MER
