  1. 1. Techno-economic analysis of large-scale production of e-methanol, via CO2- hydrogenation, in Power-to-X

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Jonathan Ahlbäck Ikonen; [2023]
    Nyckelord :Power-to-X; E-methanol; Hydrogen Production; CO2-hydrogenation; Methanol Synthesis; Decarbonisation; Chemical Engineering; Technology and Engineering;

    Sammanfattning : Global levels of carbon emissions are constantly rising causing irreversible damages to ecosystems. The heavy transport sector and the industrial sector are responsible for large amounts of the emissions on a yearly basis. LÄS MER

  3. 2. Tuning the composition of metallic nanoparticles for catalytic applications

    Master-uppsats, KTH/Kemi

    Författare :Anthony Ropp; [2021]
    Nyckelord :catalysis; nanoparticles; frustrated Lewis pairs; synthesis; core-shell;

    Sammanfattning : Industries’ interest in nanomaterials is tremendous and catalysis is one of their applications. Catalysts allow reactions to occur under milder conditions, avoiding committing excessive heat or pressure to foster reactions. LÄS MER

  4. 3. Conversion of CO2 to higher alcohols

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Joshua Higby; [2020]
    Nyckelord :CO2 hydrogenation; higher alcohols; modelling; process intensification;

    Sammanfattning : I rapporten framgår det en termodynamisk analys för reverse water gas shift med att sammanmata etanol för att undvika det långsammaste steget i reaktionen för att producera högre alkoholer. Ifrån ett termodynamiskt perspektiv, verkar det möjligt att utgå ifrån reverse water gas shift för att producera högre alkoholer vid 100 bar med en temperatur på 300C . LÄS MER

  5. 4. Techno-economic feasibility study of a methanol plant using carbon dioxide and hydrogen

    Master-uppsats, KTH/Energiteknik

    Författare :Judit Nyari; [2018]
    Nyckelord :methanol; CCU; CO2 hydrogenation; simulation; Aspen; economics; levelised cost;

    Sammanfattning : In 2015, more than 80% of energy consumption was based on fossil resources. Growing population especially in developing countries fuel the trend in global energy consumption. This constant increase however leads to climate change caused by anthropogenic greenhouse gas (GHG) emissions. LÄS MER

  7. 5. Preparation, characterization and testing of model catalysts for CO oxidation and CO2 hydrogenation

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Stefano Albertin; [2017]
    Nyckelord :Surface science; Rhodium; Nanoparticles; Catalysis; CO2; Physics and Astronomy;

    Sammanfattning : A joint research between Lund University and Chalmers Competence Centre for Catalysis have shown promising results for a Rh-based catalyst for CO2 hydrogenation catalytic applications. The original catalyst consisted of a dispersion of nanoparticles onto a porous 3D oxide network. LÄS MER
