  1. 1. Exhaust system for hydrogen fuelled combustion engines: effect of high-water content on the SCR vanadium catalyst

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

    Författare :Cecilia Zambelli; [2023]
    Nyckelord :;

    Sammanfattning : Transportation represents a key secot in the journey towards a greener future, and alternative solutions are needed to meet the decarbonaisation need. Hydrogen internal combustion engines could represent a solution in the short-term, allowing for emission reduction with limited modification to the already existing traditional combustion engines.

  3. 2. Characterization of NOx sensor performance under oscillating pressure conditions

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

    Författare :Álvaro López Méndez; [2023]
    Nyckelord :NOx sensors; engine – out heavy duty vehicle conditions; oscillating pressure; test rig testing; NOx-sensorer; motor – ut tunga fordonsförhållanden; oscillerande tryck; testriggtestning;

    Sammanfattning : The NOx sensor is essential in the modern after-treatment system. Due to the introduction of regulations from the US, it is necessary to investigate how these sensors operate in conditions of pulsating pressures generated engine - out, after the turbocharger. LÄS MER

  4. 3. Integrating biomass gasification with electric arc furnace steel making

    Master-uppsats, KTH/Energiprocesser

    Författare :Filippa Andersson; [2023]
    Nyckelord :Electric arc furnace; EAF off-gas; gasification; CCU; process integration; Ljusbågsugn avgasrök; ljusbågsugn; förgasning; kolavskiljning; process integration;

    Sammanfattning : Utsläppen av växthusgaser ökar över hela världen och nya tekniker används för att minska utsläppen. 7% av utsläppen kommer från stålsektorn. 25% av världens stålproduktion görs via återvinningstekniken ljusbågsugn. Genom återvinningsprocessen släpps det ut 500kg CO2 per ton producerat flytande stål. LÄS MER

  5. 4. Investigation of acidic chemical recycling of poly(acetal-ester)s

    Magister-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Saga Vesterbacka; [2023]
    Nyckelord :Poly actetal-ester s; Chemical plastic recycling; Hydrolysis; Acidic degradation; Akestra; PHVT; Re-polymerization; Polymer technology; Chemistry;

    Sammanfattning : Plastic recycling is a very relevant topic from both environmental and economic viewpoints. Chemical plastic recycling is a logical solution to the plastic problems, which shows the potential to reduce plastic waste and carbon emissions from burning the plastics. LÄS MER

  7. 5. Carbon Capture for Biomass Combustion

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Anders Amundsson; [2023]
    Nyckelord :beccs; ccs; carbon capture; AMP DMSO; amine absorption; heat integration; chemical engineering; environmental engineering; Technology and Engineering;

    Sammanfattning : In order to limit global warming, bioenergy carbon capture and storage (BECCS) technologies are getting increased attention. To meet emission scenarios, an estimated 4000 carbon capture plants are expected to be required by 2030, indicating that progress in carbon capture and storage (CCS) deployment is currently lagging behind expectation.
