1. 1. Fast pyrolysis of biomass : primary products and reaction pathways

   Författare :David Usino; Tobias Richards; Weihong Yang; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fast pyrolysis; Py-GC-MS FID; Primary reactions; Cellulose; Xylan; Lignin; Birch wood; Co-pyrolysis; Mahogany; Iroko; Palm kernel shell; Biomass blend; Biomass interaction; Pretreatment; Resource Recovery; Resursåtervinning;

   Sammanfattning : Pyrolysis of biomass to produce liquid fuel and chemicals has been considered as an alternativeto fossil fuel because biomass has a lower environmental impact; moreover, it is renewable andcould be sustainable. However, the process of bio-oil production involves a series of complexchemical reactions which are dependent on the biomass feedstock and composition,temperature, heating rate as well as residence time.

3. 2. Towards molecular weight-dependent uses of kraft lignin

   Författare :Ayumu Tagami; Mikael Lindström; Olena Sevastyanova; Anna Wistrand; Stefan Backa; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kraft lignin; successive solvent fractionation; molecular weight; structural analysis; thermal stability; heat capacity; antioxidant activity; methylene blue sorption; tunicate cellulose nanofiber-starch lignin composites films; film properties; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : There is growing demand for a more efficient use of polymers that originate from renewable feedstocks due to the depleting supply of fossil fuels, based on economic and environmental reasons. As a result, lignin has attracted renewed interest as a resource for various bioproducts. LÄS MER
