Beschreibungen/Notizen

• [Display omitted] •Isolation of cellulose fibers was made from energycane using a combined NaOH and NaClO2 treatment.•Most lignin and hemicelluloses were removed from treatment.•The average width of fiber reduced to 12±5μm.•The significant changing in crystallinity occurred.•Isolated lignocellulose fibers had a one-step pyrolysis. Cellulose fibers were successfully extracted from energycane bagasse by using a combined NaOH and NaClO2 treatment. After the delignification process, most lignin and hemicelluloses were removed with a 27.4wt% yield of cellulose fibers, and the mean diameter of cellulose fibers decreased from 137±46 (raw fiber bundles) to 12±5μm (unpacked fibers). The crystallinity of cellulose fibers first decreased and then increased during the transformation from cellulose I to II, and it gradually decreased after a further NaClO2 treatment. The raw bagasse fibers showed a three-step pyrolysis process, while isolated cellulose fibers had a one-step pyrolysis process. NaClO2 treatment caused the reduction of cellulose thermal stability due to its acting on lignin and cellulose.
