Abstract Hemicellulose and lignin are not reasonably utilized during the dissolved pulp preparation process. This work
aimed to propose a process for the co-production of dissolving pulp, furfural, and lignin from eucalyptus.
High-grade dissolving pulp was prepared from eucalyptus using a combination of extremely low acid (ELA) pretreatment, Kraft cooking, and elementary chlorine-free (ECF) bleaching. The obtained pre-hydrolysate was catalytic conversion into furfural in a biphasic system, and lignin during Kraft cooking and ECF was recovered. The
process condition was discussed as well as the mass flow direction. The results showed that ELA pretreatment
could effectively remove 80.1% hemicellulose. Compared with… More >
