  1. 1. Hydrodemetallization of Petroleum - Reaction Kinetics, Activity Decay and Long-life Catalysts

    Author : Fei-Xiang Long; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catalyst deactivation; large pore catalyst; hydroprocessing; hydrodemetallization; fibrillar alumina support; hydrotreating; kinetics; metal porphyrin; multiresponse parameter estimation; HDM;

    Abstract : Hydrodemetallization (HDM) is an indispensable step in industrial catalytic hydroprocessing of residual oils. To develop improved HDM catalysts and reactors, a detailed knowledge of the reaction mechanisms and kinetics, and a good understanding of the mechanisms and process of the catalyst decaying are very important.

  2. 2. Batch Sorption Studies of Aqueous Cadmium and Lead from Contaminated Water onto Selected Biosorbents

    Author : Grace Kizito Bakyayita; Ann-Catrine Norrström; Robinah N. Kulabako; Maimuna Nalubega; Roger Thunvik; Ann-Margret Hvitt Strömvall; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biosorbents; cadmium; competitive uptake; Freundlich; pseudo-second-order kinetics; Langmuir; lead; remediation; risks; speciation; toxicity effects; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : Groundwater, wastewater, surface runoff and surface water samples from Lake Victoria basin, Uganda was assessed for trace metals contamination. Untreated, base-treated and peroxide-treated biosorbents from Albizia coriaria, Coffea canephora, Cyperus papyrus, Erythrina abyssinica and Musa spp were investigated for removal of selected trace metals from contaminated water in batch studies.

  3. 3. Nanoplasmonics for solar cells

    Author : Viktoria Gusak; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; enhanced near-field; adsorption; titanium dioxide; Localized Surface Plasmon Resonance; amorphous hydrogenated Silicon; diffusion; Langmuir kinetics; Dye-Sensitized Solar Cell; plasmonic nanoparticle; mesoporous material; diffusion-front model;

    Abstract : The main source of our energy system, the fossil fuels, will eventually be depleted and also pose environmental and climate hazards. There is thus a need for alternative, renewable energy sources. Solar (photovoltaic) cells will play an important role as one of them. READ MORE

  4. 4. Aspects of the Design of Preparative Chromatography for Purification of Antibodies

    Author : David Karlsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; ion-exchange chromatography; adsorption kinetics; gels; model calibration; robustness analysis; optimisation; ESPI; diffusion; steric mass action; Langmuir MPM; antibodies; design; Preparative chromatography; modelling; proteins; Chemical technology and engineering;

    Abstract : The development of biotechnological products is becoming more and more expensive. One type of protein attracting a great deal of attention in the biopharmaceutical industry is antibodies, which was used in this work. READ MORE

  5. 5. Equilibrium and Kinetic Batch Studies of Cadmium and Lead sorption using Low Cost Biosorbents

    Author : Grace Bakyayita Kizito; Ann-Catrine Norrström; Robinah Kulabako; Mai Nalubega; Dan Berggren Kleja; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biosorbents; cadmium; chemisorption; isotherms; kinetics; lead;

    Abstract : Agricultural wastes; Albizia coriaria, Coffea canephora, Cyperus papyrus, Erythrina abyssinica and Musa spp were evaluated for uptake of aqueous Cd2+ and Pb2+ ions in single- and binary-component solutions. Untreated, base-treated and peroxide-treated biomasses were employed in batch studies. READ MORE
