   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. Effectiveness and Evaluation of Wood Protection against Biological Deterioration Caused by Filamentous Fungi

   Författare :Olena Myronycheva; Olov Karlsson; Lone Ross; Luleå tekniska universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Träteknik; Wood Science and Engineering;

   Sammanfattning : Developing a holistic understanding of the biological deterioration of wooden material by fungi in the laboratory and outdoor conditions requires the development of new assessment procedures and tools that allow describing the process with maximum precision and accuracy. Environmental biodeterioration is a complex process including a combination of physical, chemical and biological changes, with many uncertainties limiting the predictability and effectiveness of selected preservatives after laboratory tests.
