Abstract:Thisstudyinvestigatedtheraftpulpingandelementalchlorie-free(ECF)bleachingofsevenimportedhardwoods(Vietamese acacia,Australianeucalyptusnitens,Australiablueeucalyptus,Chileaneucalyptusitens,Chileanblueeucalptus,UruguayanDuu calyptus,andThairedeucalyptus),systematicallevauatingthepulpingandbleachingperformancesofthesehardwoods.Theresults showed that blue eucalyptus performed exceptionally well in terms of pulping yield(over 55% )and oxygen bleaching efficiency(over 45% ).Eucalyptusnitens bleached pulp had longer fiber length(approximately 0.94mm )and finer fiber diameter(approximately (20 0.063mg/m ),resulting in prepared paper withgoodtensileindex,exceeding 99.ON·m/g.Therefore,both blue eucalyptus and eucalyptus nitens weridealrawmaterialsforbleachedkraftpulping.ThepulpingperformanceofUruguayan DuneucalyptusandThairedeucalyptus was poor,and process adjustments were needed to reduce costs and improve efficiency.
