  2. 1. Biomass conversion through syngas-based biorefineries : thermochemical process integration opportunities

    Author : Katarina Åberg; Anders Nordin; Linda Pommer; Erik Dahlquist; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; biorefinery; thermochemical conversion; torrefaction; slow pyrolysis; gasification; process integration; carbon negativity;

    Abstract : The replacement of fossil resources through renewable alternatives is one way to mitigate global climate change. Biomass is the only renewable source of carbon available for replacing oil as a refining feedstock. Therefore, it needs to be utilized not just as a fuel but for both biochemical and thermochemical conversion through biorefining. READ MORE

  4. 2. Syngas production by integrating thermal conversion processes in an existing biorefinery

    Author : Katarina Åberg; Anders Nordin; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; biofuels; syngas; gasification; torrefaction; methane reforming; H2 CO ratio; system analysis; CO2 negativity;

    Abstract : The use of carbon from fossil-based resources result in changes in the earth’s climate due to emissions of greenhouse gases. Biomass is the only renewable source of carbon that may be converted to transportation fuels and chemicals, markets now fully dominated by traditional oil supply. READ MORE
