  1. 1. Modeling adsorption of organic compounds on activated carbon a multivariate approach

    University dissertation from Umeå : Kemi

    Author : Jufang Wu; Umeå universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; activated carbon; adsorption; adsorption capacity; adsorption rate; PCA; PLS; binary mixtures; Dubinin-Radushkevich; Wheeler-Jonas; Analytisk kemi; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Abstract : Activated carbon is an adsorbent that is commonly used for removing organic contaminants from air due to its abundant pores and large internal surface area. This thesis is concerned with the static adsorption capacity and adsorption kinetics for single and binary organic compounds on different types of activated carbon. READ MORE

  2. 2. Refining of hydrochars/ hydrothermally carbonized biomass into activated carbons and their applications

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Wenming Hao; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrothermally carbonized biomass; activated carbon; full factorial design; activated carbon disc; nanoparticles; iron oxide; CO2 separation; methylene blue; adsorption; materialkemi; Materials Chemistry;

    Abstract : Hydrothermally treated biomass could not only be used as a fuel or a fertilizer but it can also be refined into high-value products. Activated carbons are one of those. READ MORE

  3. 3. Tailoring residue-derived carbon materials for the removal of wastewater contaminants adsorption and surface properties

    University dissertation from Umeå : Umeå universitet

    Author : Mirva Niinipuu; Umeå universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Adsorption; hydrochar; HTC; chemical activation; wastewater; pharmaceuticals; metals; surface properties; biobased residues;

    Abstract : The availability of effective, low-cost wastewater treatment is necessary for increased water recycling and the prevention of environmental pollution on a global scale. Adsorption on activated carbons is commonly applied in wastewater treatment, but the high cost of conventional activated carbons limits the use of this technique. READ MORE

  4. 4. Towards application of activated carbon treatment for pharmaceutical removal in municipal wastewater

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Victor Kårelid; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; advanced wastewater treatment; granular activated carbon; powdered activated carbon; municipal wastewater treatment; pharmaceutical removal; Biotechnology; Bioteknologi;

    Abstract : Many pharmaceuticals are found in municipal wastewater effluents due to their persistence in the human body as well as in conventional wastewater treatment processes. This discharge to the environment can lead to adverse effects in aquatic species, such as feminization of male fish. READ MORE

  5. 5. Structuring porous adsorbents and composites for gas separation and odor removal

    University dissertation from Stockholm, Sweden : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Neda Keshavarzi; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Structure; pulsed current processing; zeolite; aluminophosphate; activated carbon; CO2 separation; adsorption; durability; cellulose; film; coating; materialkemi; Materials Chemistry;

    Abstract : Porous zeolite, carbon and aluminophosphate powders have been colloidally assembled and post-processed in the form of monoliths, flexible free standing films and coatings for gas separation and odor removal. Zeolite 13X monoliths with macroporosites up to 50 vol% and a high CO2 uptake were prepared by colloidal processing and sacrificial templating. READ MORE
