Study on the variation of chemical components with age in young Eucalyptus Camaldulensis for pulping industry

This research was aimed to study the effect of Eucalyptus Camaldulensis tree age (4, 6, 8 years old) on the chemical components for pulping industry. Chemical analyzes were performed for each age group three times and the results of chemical components were compared with each other. The percentages of cellulose, hemicellulose, lignin, extractives and ash for 4 year old trees were 37.9, 34.41,23.7,3.22 and 1.05 respectively and for 6 year old trees were 41.08, 30.7, 25.39, 4.62 and 0.81 respectively and for 8 year old trees were 41.9, 29.53, 26.86, 6.03 and 0.54 respectively. Finally because ofhaving more cellulose and less ash, the 8 year old trees could be better for pulping industry.
