  1. 16. Model studies on the effects of composition differences of direct reduction pellets and an adaptive addition of slag formers for the EAFprocess

    University essay from KTH/Materialvetenskap

    Author : Björn Keskitalo; [2015]
    Keywords : ;

    Abstract : This work has been conducted to study the effect of different types of iron ore pellets on an EAFbased steel production. The study has focused on how the chemical composition of the raw materialsinfluences the slag amount and as a result the EAF operation. It is also shown that the raw materialselection can be optimized for a better slag practice. READ MORE

Studien är främst begränsad till ämnena bipollen, kreatin, L-karnitin, solhatt (Echinacea spp.) och fjärilsranka (Schizandra chinensis). READ MORE

  4. 18. Rostfärgat slam i dränagesystem vid vattenkraftsanläggningar : orsaker och åtgärder

    University essay from SLU/Dept. of Energy and Technology

    Author : Anders Hamrén; [2013]
    Keywords : vattenkraft; dammar; järnbakterier; flödesmätning; dränagesystem;

    Abstract : From embankment dams is something that has long been noticed and given rise to different questions. The most serious question is if the sludge is a result of inner erosion through the dam, and thus consists of material transported from the dam. READ MORE

  5. 19. Observation of methanogenesis and potential iron-dependent anaerobic oxidation of methane in old lake sediments, a study of two boreal forest lakes.

    University essay from Institutionen för biologisk grundutbildning

    Author : Elias Broman; [2013]
    Keywords : Limnology; Lake; Sediment; Methane; Anaerobic oxidation;

    Abstract : Organic and inorganic carbon can enter inland waters in different ways, and often a considerable amount of this carbon is coming from terrestrial input. Once this terrestrial carbon enters a lake, the carbon may be degraded, mineralized or eventually buried in the sediment. READ MORE

  6. 20. In-situ remediation of benzene-contaminated groundwater – A bench-scale study.

    University essay from KTH/Mark- och vattenteknik

    Author : Sofia Billersjö; [2013]
    Keywords : ISCO; bioremediation; hydrogen peroxide; Fenton’s reagent; persulfate; calcium peroxide;

    Abstract : During the construction of the new urban area in the north-eastern part of Stockholm, Stockholm Royal Seaport, groundwater with extremely elevated levels of the carcinogenic aromatic hydrocarbon benzene was discovered in the area Hjorthagen. Such a contamination can be remediated in-situ by the use of chemical oxidation and biodegradation. READ MORE
