  1. 1. Utilization of Biomethane in Decarbonising India´s Energy Mix

    Master-uppsats, KTH/Energiteknik

    Författare :Niraj Ravindra Kunkulol; [2023]
    Nyckelord :Anaerobic digestion; biogas; biomethane; membrane filtration; pressure swing adsorption; Anaerob rötning; biogas; biometan; membranfiltrering; trycksvängadsorption;

    Sammanfattning : This thesis investigates the potential of biomethane production in India, the impact of its integration into the energy mix, and the corresponding Greenhouse Gases (GHG) emission and potential reduction. India, with its huge population and being an agriculturally rich country, produces gigantic amounts of biodegradable waste from various sources such as Municipal Solid Waste (MSW),agricultural waste, animal husbandry, sugar industry, etc. LÄS MER

  3. 2. Techno-economic Assessment of Carbon Capture from Low Concentration Streams

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Prithvi Kiran Joshi; [2023]
    Nyckelord :Carbon capture; industrial emissions; low concentration; MEA; Benfield; absorption; Immobilised Amine; adsorption; Kolavskiljning; industriella utsläpp; låg koncentration; MEA; Benfield; Absorption; Immobiliserad amin; Adsorption vi;

    Sammanfattning : Investments in carbon capture from industrial emissions have been on the rise in recent years, having reached over $200 million in 2021 as compared to 2015’s $13 million. The Paris Agreement, signed by 196 parties globally in 2015, is purported to be the primary driver for this, with its ambitious goal of limiting global surface temperature rise to 1. LÄS MER

  4. 3. A Quantum Chemical Investigation of Chemical Vapour Deposition of Fe using Ferrocene and Plasma Electrons

    Master-uppsats, Linköpings universitet/Kemi

    Författare :Felicia Andersson; [2023]
    Nyckelord :Quantum chemistry; Ferrocene; Silver; Ag 111 ; Plasma electrons; Surface chemistry; Electronic structure; DFT; Kvantkemi; Ferrocen; Silver; Ag 111 ; Plasmaelektroner; Ytkemi; Elektronstruktur; DFT;

    Sammanfattning : Thin films provide a remarkable asset, as depositing a thin surface layer can completely alter a material’s characteristics and provide new, inexpensive, and valuable properties. In 2020, a new Chemical Vapour Deposition (CVD) approach was developed at Linköping University, using plasma electrons as reducing agents for the deposition of metallic thin films. LÄS MER

  5. 4. Design and processing of metal-organic frameworks for greenhouse gas capture

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Evelina Wiksten; [2023]
    Nyckelord :Metal-organic frameworks; zeolitic imidazolate frameworks; carbon capture; gas adsorption; direct ink writing;

    Sammanfattning : Anthropogenic emission of greenhouse gases has long been suspected to contribute to global warming and climate change. Most greenhouse gases are emitted in a mixture, so efficient methods and materials to separate and capture the gases are in demand in order to reduce emissions. LÄS MER

  7. 5. Moisture Transport in PA6

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Emanuel Markström; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Polyamide 6 (PA6) is known to absorb water from its environment due to its chemical structure. The water absorption leads to changes in the mechanical properties as well as an increase in volume (swelling) of the polyamide. LÄS MER
