7. 10. Biomass conversion through syngas-based biorefineries : thermochemical process integration opportunities

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

   Sammanfattning : 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. LÄS MER
