  1. 1. Chemical Kinetic Modeling of the Combustion of NH3/H2 and NH3/syngas Fuel Mixtures Using a Large Amount of Experimental Data

    University essay from Lunds universitet/Kemiska institutionen

    Author : Andras Szanthoffer; [2022]
    Keywords : Ammonia combustion; Detailed chemical kinetic mechanisms; Quantitative mechanism comparison; Local sensitivity analysis; Chemical Physics; Chemistry;

    Abstract : Nowadays, due to the global climate change, it is extremely important to find alternative fuels to reduce the utilization of fossil fuels and the emission of air pollutants such as carbon dioxide (CO2), hydrocarbon pollutants, and soot. Ammonia (NH3) is a promising carbon free fuel candidate that can store and transport renewable hydrogen (H2) energy. READ MORE

  2. 2. Modeling of Biomass Gasification with Adaptation to Biological Methanation Using Aspen Plus®

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Abdallah Almashharawi; [2022]
    Keywords : Biomass gasification; Cyclone gasifier; Aspen Plus; Syngas; Synthesis gas; Biogas; Biological methanation; Methane; CO2; RISE; Meva; Gas-cleaning; Gas cleaning; equilibrium; kinetic; pyrolysis; validation; Moisture content; Chemical engineering; Technology and Engineering;

    Abstract : With reduced resources of fossil fuels and increased environmental requirements, renewable substitutes have received greater attention. The production of renewable chemicals and fuels through biomass gasification presents a promising route to drive this energy transition. READ MORE

  3. 3. Magnetic Ionic Liquids in Solutions and Emulsions

    University essay from KTH/Materialvetenskap

    Author : Simon Bruno; [2022]
    Keywords : ionic liquids; microemulsion; magnetic response; surfactant; co-surfactant; imidazolium cation; polarity; chain length effect; joniska vätskor; mikroemulsion; magnetisk respons; surfaktant; co-surfaktant; imidazoliumkatjon; polaritet; kedjelängdseffekt;

    Abstract : This research thesis reports experimental work done to design a stable magneticmicroemulsion of ionic liquid in 2-ethylhexyl laurate with the help of an ionic surfactant andan alcohol co-surfactant. The ionic liquids tested were based on a 1,3-dialkylimidazoliumcation with different alkyl chain lengths and a tetrachloroferrate anion ([FeCl4]+) to ensure theemulsion is sensitive to applied magnetic fields.

  4. 4. BVOC emission variability for Norway spruce (Picea abies) in Hyltemossa, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alexandra Arnsteg; [2022]
    Keywords : BVOC; isoprene; monoterpenes; induced emission; light dependency; temperature; Norway spruce.; Earth and Environmental Sciences;

    Abstract : Biogenic volatile organic compounds (BVOC) are known as hydrocarbons emitted into the atmosphere from the biosphere. They have physiological and ecological functions such as communication within the plant and plant – plant, protection against environmental stress factors and defense against herbivores attack.

  5. 5. Analysis of Aircraft Emissions Based on Flight Trajectory : ATR 72-500 trajectory and emission study

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Gustav Forsberg; Carl-Michael Sundberg; [2022]
    Keywords : trajectory; emissions; Boeing Fuel Flow;

    Abstract : Emissions related to aviation have during the last decades become an important topic of discussion. Besides carbon dioxide ($CO_2$) which is the major pollutant from air travel, other gas emissions such as hydrocarbons ($HC$), nitrogen oxides ($NO_x$), carbon monoxide ($CO$) and sulfur oxides ($SO_x$) also need to be investigated.
