Colorimetric patterns of wood pellets and their relations with quality and energy parameters (2014, background): “The exposure of raw material to high temperatures during drying changes both its chemical properties and external appearance affecting also the resulting pellet color [18,19].”
Recent innovations in analytical methods for the qualitative and quantitative assessment of lignin (2015, methodology): “UVRR spectroscopy was also used to study how increases in temperature affected Scots pine samples [109].”
Control of wood thermal treatment and its effects on decay resistance: a review (2016, unknown): “2002, Nuopponen et al. 2004), leading to set up various industrial processes.”
Heat-induced colour changes of pine (Pinus pinaster) and eucalypt (Eucalyptus globulus) wood (2008, background): “The thermal degradation starts by deacetylation of hemicelluloses and the released acetic acid acts as a depolymerization catalysist which further increases polysaccharide decomposition (Tjeerdsma et al. 1998; Sivonen et al. 2002; Nuopponen et al. 2004).”
Effect of Heat Treatment on Color Changes, Dimensional Stability, and Mechanical Properties of Wood (2012, background): “[5,9] In the process of thermal modification, hemicelluloses are degraded, lignin condenses, and the hydrophilic nature of wood decreases.[10-12] Heat treatment of wood has been carried out mostly in non-oxidative conditions, viz.”
Chemical changes of heat treated pine and eucalypt wood monitored by FTIR (2013, background): “They start by deacetylation of hemicelluloses followed by depolymerization catalysed by the released acetic acid (Tjeerdsma et al. 1998, Sivonen et al. 2002, Nuopponen et al. 2004).”
Wood modification by heat treatment: a review. (2009, background): “374 Furfural and hydroxymethylfurfural are degradation products of pentoses and hexoses, respectively (Nuopponen et al. 2004).”
Extractive composition and summative chemical analysis of thermally treated eucalypt wood (2008, background): “Xylose and arabinose contents decreased with the treatment severity more than the other sugars and, accordingly, eucalypt xylans are more susceptible to thermal degradation than mannans as reported for softwoods (Alén et al. 1995; Nuopponen et al. 2004).”
