Abstract

This study investigated the chemical properties of Brutian pine (Pinus brutia Ten.) wood samples collected at altitudes of 800 m, 900 m, and 1000 m and the behaviors of the chemical components of the same materials during kraft pulping. Chemical component analysis indicated that the wood and pulp sample from 1000 m contained higher quantities of holocellulose and α-cellulose, and a lower quantity of lignin. For both wood and pulp samples, a continuous increase in holocellulose and α-cellulose contents and a continuous decrease in lignin content were observed with increasing altitude. Gas chromatography analysis of monosaccharides determined that the highest cellulose and hemicellulose contents were obtained from the wood and pulp sample from 1000 m. Quantity of these components increased with increasing altitude. Lastly, kraft pulping degraded 14.10-15.70% of cellulose, 56.49-61.35% of galactoglucomannan, 65.75-69.61% of arabinoglucoronoxylan, and 92.42-93.48% of lignin in the samples.

Özet

Bu çalışmada, 800 m, 900 m ve 1000 m’lik yükseltilerden elde edilen kızılçam (Pinus brutia Ten.) odun örneklerinin kimyasal özellikleri ve aynı materyallerin kimyasal bileşenlerinin kraft kağıt hamuru üretimi sırasındaki davranışları incelenmiştir. Kimyasal bileşen analizi, 1000 m'den alınan odun örneği ve üretilen kağıt hamurunun diğerlerine kıyasla daha yüksek miktarlarda holoselüloz ve α-selüloz, bununla birlikte daha düşük miktarlarda lignin içerdiğini göstermiştir. Hem odun hem de kağıt hamuru örnekleri için, artan yükselti ile birlikte holoselüloz ve α-selüloz içeriklerinde sürekli bir artış, lignin içeriğinde ise sürekli bir azalma gözlenmiştir. Monosakkaritlerin gaz kromatografisi analizi, en yüksek selüloz ve hemiselüloz içeriğinin 1000 m'den alınan odun örneği ve üretilen kağıt hamurunda bulunduğunu ortaya koymuştur. Bu bileşenlerin miktarları yükselti arttıkça örneklerde artış göstermiştir. Sonuç olarak, kraft kağıt hamuru üretimi sırasında, selülozun %14.10-15.70, galaktoglukomannanın %56.49-61.35, arabinoglukoronoksilanın %65.75-69.61 ve ligninin %92.42-93.48'inin çözündüğü görülmüştür.
