TL;DR: In this paper, a slow pyrolysis of pine sawdust was conducted using a gas sweeping fixed-bed reactor for suppressing the secondary reactions of tar vapor, and the degradation of hemicellulose started at 200-300°C, forming many sorts of liquid products, such as saccharide, furan, carboxylic acid, ketone and aldehyde, with the occurrence of dehydration, decarboxylation and decarbonylation.

TL;DR: In this paper, a novel and facile synthetic method for fabricating graphitic carbon nanostructures (GCNs) from sawdust is presented, which is based on the use of catalysts (Fe or Ni) that allows the direct conversion of sawdust into highly graphitized carbon material.
Abstract: We present a novel and facile synthetic method for fabricating graphitic carbon nanostructures (GCNs) from sawdust. This method is based on the use of catalysts (Fe or Ni) that allows the direct conversion of sawdust into highly graphitized carbon material. The following procedure was used to obtain these graphitic nanoparticles: (a) impregnation of the sawdust particles with iron or nickel salts, (b) carbonization of the impregnated material at a temperature of 900 or 1000 °C, and (c) selective removal of the non-graphitized carbon (amorphous carbon) by an oxidant (KMnO4). The resulting carbon is made up of nanosized graphitic structures (i.e., nanocapsules, nanocoils, nanoribbons), which have a high crystallinity, as evidenced by TEM/SAED, XRD and Raman analysis. These GCNs were used as supports for platinum nanoparticles. Such prepared electrocatalysts show an electrocatalytical surface area close to 90 m2.g-1 Pt, and they present a similar or higher electrocatalytic activity toward methanol electroox...

TL;DR: In this paper, microwave pyrolysis of Douglas fir sawdust pellet was investigated to determine the effects of reaction temperature and time on the yields of bio-oil, syngas, and charcoal using a central composite design (CCD) and response surface analysis.

TL;DR: The decomposition of hemicelluloses was found to be responsible for the significant changes of chemical, physical and mechanical properties of the torrefied sawdust, including energy content, particle size distribution and moisture absorption capacity.
