  3. 2. Bio-coal as an alternative reducing agent in the blast furnace

    Författare :Asmaa El-Tawil; Lena Sundqvist Öqvist; Bo Björkman; Henrik Saxen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Devolatilization; torrefied biomass; bio-coal; volatile matter; reduction; blast furnace; Process Metallurgy; Processmetallurgi;

    Sammanfattning : The steel industry is aiming to reduce CO2 emissions by different means; in the short-term, by replacing fossil coal with highly reactive carbonaceous material like bio-coal (pretreated biomass) and, in the longer term, by using hydrogen. The use of bio-coal as part of top charged briquettes also containing iron oxide has the potential to lower the thermal reserve zone temperature of the Blast furnace (BF) and, due to improved gas efficiency, thereby give a high replacement ratio to coke.

  4. 3. Influence of the properties of bio-coal as a substitute for fossil coal in carbon composite agglomerates and in coke

    Författare :Asmaa El-Tawil; Lena Sundqvist Ökvist; Bo Björkman; Timo Fabritius; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bio-coal; devolatilization; bio-agglomerates; bio-coke; Centrumbildning - Centrum för avancerad gruvteknik och metallurgi CAMM ; Centre - Centre for Advanced Mining Metallurgy CAMM ; Process Metallurgy; Processmetallurgi;

    Sammanfattning : The iron-ore-based blast furnace (BF) process is still the most dominant method for producing metallic iron units for steelmaking, and the BF is also the main contributor to the 7-9% of global CO2 emissions which, according to World Steel Association, originate from the steel industry.  The steel industry is aiming to reduce CO2 emissions by different means.

  5. 4. Long-term molecular epidemiology of extended-spectrum β-lactamase producing Escherichia coli in a low-endemic setting

    Författare :Anna Fagerström; Bo Söderquist; Paula Mölling; Martin Sundqvist; Katarina Persson; Linus Sandegren; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Escherichia coli; extended-spectrum β-lactamase; whole genome sequencing; plasmids; hybrid assembly; environment; IncI1; ST131;

    Sammanfattning : Escherichia coli is a commensal inhabitant in the gastro-intestinal tract of humans and animals but it is also the most common bacterial species causing urinary tract infection, which ranges in severity from distal cystitis to urosepsis and septic shock. During the past decades, the prevalence of antibiotic resistant E. LÄS MER
