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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE

  3. 2. Effects of stratospheric wildfire smoke on ozone depleting substances and ozone levels in the northern midlatitudes

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Christopher Grüner; [2023]
    Keywords : Physics and Astronomy;

    Abstract : The goal of this project was to examine whether there are correlations between recent wildfires in the northern hemisphere and stratospheric ozone anomalies in the midlatitudes following the creation of ozone depleting substances. To achieve this goal, data from the Aura satellite's Microwave Limb Sounder instrument was used and processed with self-written Python scripts. READ MORE

  4. 3. Hydrogen Absorption in Metal Hydrides : Transmission of light in relation to hydrogen concentration and site occupancy of ultrathin vanadium films

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : David Sörme; [2022]
    Keywords : metal hydrides; iron-vanadium superlattice; hydrogen; hydrogen site occupancy; hydrogen concentrationm; hydrogen storage;

    Abstract : In this study the effect of hydrogenation on the optical properties in the wavelength range 400-1023 nm of an ultrathin iron-vanadium superlattice is investigated. Specifically, mea- surements of transmission are performed under different states of hydrogenation, along with measurements of absolute hydrogen concentration and hydrogen site occupancy. READ MORE

  5. 4. Prospective Life Cycle Assessment of an Electrochemical Hydrogenation Process Over a Nickel Foam Cathode

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hanson Appiah-Twum; [2022]
    Keywords : Scale-up; early process design; catalysis; environmental impact; hotspot analysis; green chemistry;

    Abstract : The need for a safe and sustainable chemical industry has called for the development of emerging technologies with improved environmental performance. In this study, an emerging electrochemical hydrogenation process over Ni foam is being developed at the laboratory scale with an expectation of less environmental impacts than a conventional palladium on carbon hydrogenation process.

  6. 5. Tuning the composition of metallic nanoparticles for catalytic applications

    University essay from KTH/Kemi

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

    Abstract : 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. READ MORE
