  1. 1. A new generation ofsmart food packaging : A combination of releasing anti-microbial and generation carbon dioxide inmeat packaging

    University essay from Karlstads universitet

    Author : samar salahieh; [2023]
    Keywords : adsorption isotherms; desorption kinetics; benzoic acid; thymol; modified calcium carbonate; silica gel; carbon dioxide; food pad.; adsorptionsisotermer; desorptionskinetiken; bensoesyra; tymol; modifierat kalciumkarbonat; kisel gel; koldioxid; food pad.;

    Abstract : Abstract Food sustainability depends significantly on packaging since it helps maintainfood safe and fresh throughout its shelf life, resulting in the least amount ofwaste and the least negative environmental impact. The main objective of thisstudy is to determine the adsorbed and released amount of antimicrobial agents(benzoic acid and thymol) on modified calcium carbonate (MCC) by investigating adsorption isotherm at 25°C and desorption kinetics at both 22°C and5°C of anti-microbial to identify potential solutions to enhance the long-termsustainability of fresh products such as meat.

  2. 2. Experimental characterization of a specific chemisorbent and a physisorbent for direct air capture application : Analyzing the effect of parameters such as desorption temperature, humidity and varying CO2 partial pressure on the performance of the adsorbent material. (Thesis work carried out at The Netherlands Organization for Applied Scientific Research (TNO), Delft, The Netherlands)

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

    Author : MIT RAKESH SURATI; [2022]
    Keywords : ;

    Abstract : Climate change has become an indisputable threat to the planet with global warming being at the forefront. With continuous usage and combustion of fossil fuels, the atmospheric CO2 concentration has kept on increasing leading to higher average temperatures globally. READ MORE

  3. 3. Biobased carbon aerogels incorporated with zeolite nanoplates for carbon dioxide adsorption

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Maria Harila; [2021]
    Keywords : biobased; carbon aerogel; lignin; cellulose nanofiber; adsorption; carbon dioxide; zeolite nanoplate;

    Abstract : Over the last 100 years there has been an increase of greenhouse gases (CO2, CH4 and N2O) in the atmosphere. These gases cause several problems with the climate on Earth, such as increasing problems with extreme weather. One way to decrease the outlet of carbon dioxide is by adsorption and capture of CO2.

  4. 4. A model for heterogenic catalytic conversion of carbon dioxide to methanol

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Elin Johannesson; [2020]
    Keywords : Carbon dioxide; methanol; heterogeneous catalysis; zinc oxide; computational chemistry; density functional theory;

    Abstract : Since our society became industrialised, the levels of carbon dioxide in our atmosphere have been steadily rising, to the point where it in early 2020 at is 413 ppm. The high concentration is causing several troubling effects worldwide because of the increase in mean temperature that it creates, which causes longer draughts, more severe floods, and rising seawater levels to name a few.

  5. 5. 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.
