  1. 1. Modeling competitive adsorption of binary mixtures of volatile organic compounds

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Michelle Janus; [2023]
    Keywords : ;

    Abstract : Adsorption is a common technique for the removal of volatile organic compounds (VOCs) from industrial waste streams. The multi-component adsorption on zeolites, particularly the interactions between VOCs and water vapor is sparsely understood and is yet to be described by empiric and full-physical models.

  3. 2. Iron-catalyzed graphitization of biochar to produce graphitic carbon materials

    University essay from KTH/Materialvetenskap

    Author : Ziyi Shi; [2021]
    Keywords : graphite; biochar; catalyst; catalytic graphitization; grafit; biokol; katalysator; katalytisk grafitisering;

    Abstract : Demand for high-quality graphite is expected to experience an extraordinary growth rate, in large part due to its wide range of industrial applications such as adsorbents, lubricants, electrodes, etc. This thesis developed a novel sustainable approach to produce green-graphite materials by applying biochar, acarbon-rich valuable by-product obtained from biomass, as a carbon precursor.

  4. 3. Experimental testing of adsorbents for H2S removal in industrial applications : A comparative study on lifetime and cost effectiveness of different materials

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Fanny Boström; [2019]
    Keywords : ;

    Abstract : Harmful emissions are a global issue and cause trouble for human health and for the environment. There is a wide variety of pollutants and one pollutant is hydrogen sulfide, H2S, that is a member of the group Volatile Sulfur Compounds. READ MORE

  5. 4. Point source carbon capture by porous inorganic carbonates

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Jonas Hultberg; [2018]
    Keywords : Carbon capture; Gas separation; Adsorbent; Inorganic carbonates; Point source; Carbon dioxide; Kolavskiljning; Adsorbenter; Oorganiska karbonater; Punktkälla; Koldioxid;

    Abstract : Mesoporous inorganic carbonates (MIC) was synthesized and tested as adsorbents for CO2, using vacuum and temperature swing adsorption. Mesoporous magnesium carbonate (MMC), mesoporous calcium carbonate (MCC) and mesoporous calcium magnesium carbonate (MCMC), all included in MIC, are exceedingly porous with an amorphous structure.

  6. 5. Calibration and Application of Passive Sampling in Drinking Water for Perfluoroalkyl Substances

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Caroline Persson; [2015]
    Keywords : Perfluoroalkyl substances PFASs ; passive sampling; Polar organic compound integrative sampler POCIS ; sampling rate; calibration; application; drinking water; Perfluoroalkylsubstanser PFAS ; passiv provtagning; Polar organic compound integrative sampler POCIS ; provtagningsshastighet; kalibrering; tillämpning;

    Abstract : Perfluoroalkyl substances (PFASs) are global environmental contaminants and a need for monitoring levels has arisen due to their persistency and their ability to bioaccumulate. One relatively novel method of monitoring for both long and short time intervals and generating time-weighted average (TWA) concentrations is passive sampling for which no power, maintenance and supervision is required.
