  1. 1. Increase of biogas production by incorporating residual streams from agriculture

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Stephanie Fjäll; [2022]
    Keywords : Anaerobic digestion; Agricultural residue; Lignocellulosic biomass; Mechanical pretreatment; Biogas production; Biorefinery; Chemical engineering; Agriculture and Food Sciences; Technology and Engineering;

    Abstract : To expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. READ MORE

  3. 2. Negative CO2 Emissions from Chemical Looping Combustion: Gas Cleaning for CO2 Storage

    University essay from KTH/Kemiteknik

    Author : Laura Raud Pettersson; [2022]
    Keywords : Chemical Looping Combustion; Flue Gas Treatment; Negative emissions; Biomass; CCS; Linde Hampson; Cryogenic Separation; Kemcyklisk Förbränning; Rökgasrening; Negativa Utsläpp; CCS; Biomassa; Linde Hampson; Kryogen Destillation;

    Abstract : Kemcyklisk förbränning (CLC) involverar en icke komplex separation av den bildade koldioxiden (CO2) efter förbränningen eftersom syret (O2) överförs till bränslet via en syrebärare som cirkulerar mellan luft- och bränslereaktorn. Eftersom O2 separeras effektivt från kvävgasen (N2) i luftreaktorn, erhålls en produkt gas som till majoriteten består av CO2 och vatten (H2O). READ MORE

  4. 3. Assessment of biochar potential as a land-based emission mitigation measure in Colombia

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Eileen Jimena Torres Morales; [2022]
    Keywords : agriculture; biochar; climate change mitigation; carbon sink; Colombia; land-based mitigation technologies LMT ; nature-based solutions NBS ; PESTEL Political; Economic; Social; Technological; Environmental Legal ; pyrolysis; residual biomass; soil adaptation; techno-economic analysis.; jordbruk; biokol; begränsningar av klimatförändringar; kolsänka; Colombia; land-baserad begränsningsteknik; Naturbaserade lösningar NBS ; PESTEL Political; Economic; Social; Technological; Environmental Legal ; pyrolys; restbiomassa; jordförbättring; Teknisk-ekonomisk analys;

    Abstract : There is an urgent need to mitigate carbon emissions to the atmosphere to reduce the negative effects of climate change. Countries have pledged national strategies to reach their climate change mitigation goals in their Nationally Determined Contributions (NDC). In the case of Colombia, the country envisions becoming carbon neutral by 2050. READ MORE

  5. 4. Design of a Polygeneration system in Filipinas ETCR, Colombia

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Germán Ropero Pérez; [2021]
    Keywords : ;

    Abstract : This project has addressed the design of a cost-effective Polygeneration system that guarantees a continuous, equitable and environmentally friendly energy supply for the rural settlement of Filipinas ETCR, (in Spanish, Espacios Territoriales de Capacitación y Reincorporación) Colombia, which is currently not achieved, due to a system that relies on the national electricity grid (with numerous outages) and on LPG (Liquefied Petroleum Gas) and wood to meet the thermal demand, mainly for cooking. For this purpose, in addition to the current energy supply situation, the energy demand according to type (electricity and heat) and sector (residential, commercial and agro-livestock) is characterized.

  6. 5. Alkaline wet oxidation of biorefinery lignin from wheat straw

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maja Lindblad; [2021]
    Keywords : alkaline wet oxidation; lignin oxidation; wheat straw; chemical pretreatment; biorefinery lignin; anaerobic digestion; response surface-modelling; chemical engineering; Technology and Engineering;

    Abstract : Climate change and depletion of fossil resources have generated a need for energy production based on renewable resources such as lignocellulosic biomass. Agricultural residues, like wheat straw, is lignocellulosic biomass that could contribute to the energy supply if it was used for biogas production. READ MORE
