Properties of fiberboards produced from kermes oak (Quercuscoccifera L.) and brutian pine (Pinusbrutia Ten.) woods

Abstract

In this study the utilization of kermes oak (Quercus coccifera L.) wood, which could be used as an industrial raw material for the production of fiberboard, was investigated. In the experimental design, boards were produced from mixtures of kermes oak and brutian pine (Pinus brutia Ten.

Effect of altitude on polysaccharide and lignin contents of brutian pine (Pinus brutia Ten.) wood and kraft pulp

“…The main chemical components of Brutian pine wood and pulp samples are listed in Table 1. The holocellulose contents of wood samples were in agreement with the values of 70.8%, 72.57%, 72.07%, 72.64%, and 72.09% reported for Brutian pine wood by Kırcı (1991), Kılıç et al (2010), Güler and Yaşar (2018), Beram and Yasar (2020), and Güler and Yaşar (2020). Similarly, the α-cellulose contents of wood samples were consistent with the values of 48.56%, 46.5%, 48.16%, 48.23%, and 48.24% observed by Tutuş et al (2012), Taş (2017), Güler and Yaşar (2018), Beram and Yasar (2020), and Güler and Yaşar (2020).…”

Lignin contents of wood samples in this study were higher than the previously reported klason lignin contents of 27.4%, 27.34%, 27.60%, 27.16%, 27.98%, and 27.33% demonstrated by Kırcı (1991), Kılıç et al (2010), Tutuş et al (2012), Güler and Yaşar (2018), Beram and Yasar (2020), and Güler and Yaşar (2020).…”

However, klason lignin content reflects only the acid-insoluble part of the total lignin content of wood (Rodrigues et al, 1999).…”

“…GC chromatograms of Brutian pine wood (A) and pulp (B) samples Monosaccharide and uronic acid contents of Brutian pine wood and pulp samples are indicated in Table2. The monosaccharide composition of Brutian pine wood samples was in agreement with observations byYaşar (2014),Yaşar and Güler (2018), andGüler and Yaşar (2020). Glucuronic acid was not found in the pulp samples, as that this unit is more prone to decomposition in kraft pulping than other monosaccharide units(Fengel and Wegener, 1984).…”
