Pilot Study on P-RC APMP Pulping of Poplar Treated by White-rot Fungi
(0) Poplar chips were treated by two white-rot fungi (Phanerochaete chrysosporium and Tranetes versicolor)separately,and then they were pulped by two P-RC APMP sequences (dosages of H2O2 3％ and 6％ respectively).Pulping energy consumption,pulp strength properties and optical properties were tested.The result showed that after the white-rot fungi treatments,the pulping energy consumptions were reduced(in the two sequences,energy savings for the Phanerochaete chrysosporium treatment were 31.62％ and 14.37％,and for the Tranetes versicolor treatment,11.00％and 14.37％ respectively),the strength properties of pulp was improved(at 350 CSF,Ph.c and T.v pretreatment improved the breaklength of pulp by 25％ in sequence 1; in sequence 2,Ph.c treatment improved the breaklength of pulp by 6.1％,T.v treatment improved the breaklength of pulp by 10.4％; in the two sequences,Ph.c treatment improved the burst index by 18.18％ and 20.00％,T.v treatment,10.91％ and 28.00％),and the brightness was lost a little,but the bleachability was improved.
