Chemical Compositions of Fast-growing Birch Wood Species from Different Provenances
An experiment was conducted to study the chemical compositions of six fast-growing birch wood species from different provenances at Maoershan Experimental Forestry Center of Northeast Forestry University in Shangzhi City by the conventional pulping and papermaking methods using natural secondary birch wood as a control. The chemical composition of different wood samples was compared, and the effect of chemical composition on pulping and papermaking was discussed. There was no significant difference in holocellulose content of wood samples between the fast-growing provenances and the natural provenance. The lignin content of fast growing wood samples was a little lower while the pentosan content was much lower than that of the reference samples, which was beneficial to increase the pulping yield. Wood samples from Liupan-shan and Maoershan are superior to other wood samples in pulping properties.
