7. 25. Alkali Release and Effects on Biomass Thermal Conversion Processes

   Författare :Yaxin Ge; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Co-conversion; Alkali; Biomass; bed material; thermal conversion; online measurements;

   Sammanfattning : High alkali content is an important feature of biomass, and it has a series of implications for thermal conversion processes. This thesis focuses on the release of alkali during various biomass thermal conversion processes, including biomass pyrolysis, char gasification, co-conversion of different types of biomass, and thermal conversion of biomass mixed with fresh and used bed materials.
